Hey guys,

My 2yr old Lenovo Y400 has been serving me well but since January it's been experiencing random crashes especially while gaming.

I'm a casual gamer and the games I played the most are usually Dota2 and GTA4. Before any of these crashes happen, I experience a stuttering/lag gameplay (even when minimized to desktop, sounds also stutter when this happens) for a few times, then the crashes start happening.

Initially it only crashes when I'm in the 2nd or 3rd game of Dota2, but it started to happen more frequently to the extend of only 30 seconds into the game. Currently I'm also experiencing random crashes while doing normal web browsing and surfing /k.

I have run a stress test on it and this is the result of the maximum temperature:
Intel i7 Quad-core: Reaches average maximum temperature of 85C
Nvidia GT 750M: Reaches maximum temperature of 95C

It achieves this temperature without crashing, I stopped the test to prevent frying the hardware lol.

This is the reading from HWMonitor prior to the crash:
Intel i7 Quad-core: Average temperature of 75C
Nvidia GT 750M: Average temperature of 68C

and it crashes without any warning?

Now it's starting to crash while normal web browsing (rarely) with a reading of:
Intel i7 Quad-core: Average temperature of 58C
Nvidia GT 750M: Average temperature of 42C

The problem is these crashes occur randomly and there's no way to routinely recreate it. I've sent it to my retailer for checkup but he said he can't find the issue?

Anyways I've called Lenovo Support regarding this issue and they asked me to send it to an Authorized Lenovo Service Centre and its a possible thermal/ motherboard issue. Just wondering if anyone else faced this issue before? It's so frustrating that it's driving me crazy Makes me wanna toss this so called "budget gaming laptop" out the window and get a macbook because #AppleMasterRace

UPDATE 1


UPDATE 2

Thermal paste finish

Trade in for xps 15.. add 4000 only..

clean your heatsink, reapply thermal paste.
go youtube search for guide.

the stuttering/lag that you experience is mainly due to overheat and your cpu/gc throttle down the speed

i recently got an very old dell laptop, just youtubing can reach 90c. after clean it now max 50c

got buyer wan xps 15?

Where to buy?

But is dell leh..

Thanks! does the service centre do this for me? Cuz my laptop still under warranty better let them do

yes they do

wat wrong wif dell? no.1 after sales service in malaysia.. n i get u special discount.. haha

my y400 temperature more worst than urs..

even though i send to clean the whole laptop and replace thermal paste on both gpu and cpu..

the temp of gta v 3 hours



gpu max 98'c

edit: note the max temp

Try wear latex jeans then u know ur laptop feel.. haha

lol-ed
trade in + 4000 for a laptop which is having the same GPU as his current laptop.
might as well add in 300 more without trade-in to get a new Illegear with GTX 960M instead of that XPS's 750m

does princeJ wan to take trade in....

why would you want to trade-in?

trade-in + 4000 = a xps with gt750m
vs
no trade-in + 4300 = illegear with gtx 960m

in other words, who in the right mind would trade-in a laptop for just 300 bucks to get another laptop of roughly the same spec (gt750m) after adding another 4000?
good luck in finding a fool like that.

double posted somehow

then ask princeJ how much he would likely to take y400 in... tat unit around 900... tat ts wasnt even interested to trade in...

once again, why would you want to take a trade-in for a totally inferior product?
http://gpuboss.com/gpus/GeForce-GTX-960M-vs-GeForce-GT-750M
comparing GT750M (not even a GTX) which is already in his 2year old Lenovo Y400 and also the XPS vs a totally superior GTX960M from Illegear (3.6k for 960M in Y50 etc).
he can get better products without even needing to trade-in (which is a net-loss for him). no idea how you would think trade-in as a net-gain from the way you are selling it

if you still can't comprehend the logic behind this, then I got nothing to say

double psoted again

He wasn't interest in any trade in...he just wan to solve the heat...if he wan to trade in tat a different discussion...

Tat is nothing to talk bout trade in or which is superior when t's dun even bother looking at... solve his heat problem tat the main 1

Alright thanks! Shall notify them when I'm at the service centre

Yea but they are known to be not so good quality.. haha it's okay I'm not interested in it

Wahh GTA V use so much resource? I never pass 85C with the games I played but dunno why still spoilt

P.S: Thanks @evofantasy for the heads up haha. But I'm not interested in new laptops just wanna get my laptop fixed thats all.. Jgnlah gaduh2 @evofantasy @myway1985 kita semua kan kawan2 kat lyn...

Do inform after send for warranty claim. Cos im using y500.

Just wanna know the outcome. If still hve problem, i can do for you. No charge 😀

I think the problem is.. Since you already know TS is not going for trade in option, why do you offer him in the first place and why do you offer him a bad trade-in option. I think evo is not arguing whether TS should trade in or not, he is arguing why you offer a bad trade in option to TS initially.

lets put thing in perspective...when i offer him i doesnt know he dun wan to trade in... pls read the sequence... evo always jump the gun whenever he found fault in me

y dun u all go check out the machine wif all those cards 1st b4 u all say... wat i found from 700 series to 900 series (750m to 960m) the most significant is the FPS.. picture quality not huge different... n yes dell is OP.. i do agree wiif evo tat xps r expensive than illegear.. tat true... but i dun agree on the card differences.. HP omen wif gtx 860m fhd play dota 2 no different wif xps15 gt 750m QHD+... mid range is mid range la....

This post has been edited by myway1985: Apr 27 2015, 02:04 PM

No.. That is not the point. He is arguing WHY YOU OFFER A BAD TRADE IN DEAL in the first place. The problem doesn't lies in "TS want to trade in or not" or "I offer him trade in cause I dono TS don't want" etc.
It lies in "why you offer a bad trade in option to TS".
But if you still don't get it, I also quite speechless already.

P.S: 750m is obviously not a choice in here IMO, will you spend so much to get an old gpu ? Obviously you will get the new one right ? 750m can play dota 2, but can it play GTA V or BF4 at a decent rate like 960m ? Dota 2 is more on cpu side tho

Y a bad trade..xps15 priced rm6399 by dell

N i quote him a trade valued rm5000.. Qhd+ touch screen bro... Not the fhd.. I7-4712hq, 16gb ram.. Not the lowly 8gb n fhd spec

U know the different wif fhd n qhd rite

This post has been edited by myway1985: Apr 27 2015, 02:16 PM

I assume now you get what evo is arguing about right ? So shouldn't you told/justify to him why you offer that in the first place ? From your previous argument you're "avoiding" the direct and straight forward question. I'm not here to argue whether it is worth the price or not, I'm just clarifying to you what evo asked you since you can't get what he meant after 3 posts

P.S: I think MSI GE62 4k screen is still cheaper tho (but non touch)

This post has been edited by miong93: Apr 27 2015, 02:30 PM

Firstly. I told ts tat his unit thermal paste gg.. Then i ask him wan to trade in or not... I see him not interested then i stopped... Qhd+ bro... U know how nice the screen... U cant feel it from reading a review

Ge62 problem need repeat meh... Touch n none touch big different lo

Let me metaphor for u
Hd display is like 32B , fhd like 34D , qhd like 36D, wif touch screen is like perky 36D.

4k i think like 36E de... Haha but sagging coz non touch

To be honest I lol-ed at your metaphor. lol
I think sometime you tend to avoid the direct yet simple question. I still don't get why you don't want to clarify to evo on why you offer the trade in, Eg: it is a qhd 16gb laptop etc etc. You just keep arguing the TS is not interested. If it is me, I would reply like : "Why I offer 4k + trade in is because it is a qhd touch screen + 16gb ram laptop etc etc, but since the TS is not interested so no point to go any further."

2k is not much different leap from fhd, 4k is the one which have significant different.

from.. go test a qhd+ then u know the real different.. 4k of coz huge different lo... until i dare not take the xps15 4k screen (price). haha

i dun wan answer stupid question...he hit only on the gpu make feel stupid to clarify to him... ppl who read review alot confuses themself

Please do remember, not all people have money power especially current economy condition..

either its 4k UHD, QHD or what so ever IPS or gpu and so on... first of all, is this they really want? if no, dont keep suggest buy this, trade this or that... look to the problem. he is asking how to solve the randomly crash while gaming... and PLEASE SHUT UP at least if dont know how to SOLVE and DONT SPAM.. i really cant stand see this argument. looks stupid. and here is mobile computing section. not GARAGE SALES.

dear NetGi do you send ur notebook to the service center? besides that... sometimes, need to see bios update.. new bios sometimes solve this issue

Already got PPL tell netgi send to Lenovo service center de... case close Jor.. just got PPL stir it up... I shut up till somebody atk me

just ignore it...

well, actually can try repaste the thermal compound. would help alot. cause most probably ur thermal compound become cookies d

TS, best solution is repaste the thermal paste. It saves you bucks instead of a new laptop. Why change something that is not broken?

He already sending to claim warranty...

actually how long is your warranty? if under warranty, and you dont need it on a daily basis, send it, have them fix it for you.I suspect this might also have something to do with your GPU driver, or even anything that you have recently installed( excluding games, but might be some software that comes with games though ) clashing with any background running app. Whenever stuffs like this happen, try using driver sweep and install back the driver that you first ran your laptop with. Secondly, about repasting the laptop, it also depends on what thermal paste you will be replacing them with. If you are replacing them with some random budget cooler master paste, I dont think it would help a lot. Try using diamond IC if u really want to have your laptop last longer. It helps a lot.

alternatively, instead of throwing your money into #AppleMasterRace, try what other forumer already recommended, illegear. Even with 860M i think the GPU is also better than your current one, and the cooling is way better than most the laptops out there as well.

Will update you on this thread yea Initially wanted y500 too but no stock and no patience so yea..

Yea just sent it. I have already updated my bios and drivers but still got issue..

But my laptop never run above 85C leh, still possible for it to be a thermal issue? And I don't dare to open the laptop as it is still under warranty scared kena void..

Ending next month but the service center say can extend according to purchase date if provide proof of purchase so gonna ask my retailer to check records and re-issue receipt cuz my receipt already throw together with the box.. This is my only laptop/pc so its quite important to me..

I updated all drivers and bios already.. and used Lenovo Recovery to reformat but still got problem..

Any shop to recommend to buy a thermal paste? But currently don't dare to apply it myself cuz scared void warranty..

I usually use my laptop to edit videos, microsoft office, surf web and some casual gaming, so don't really need a gaming rig.. I prefer Macbook cuz of their OSX and priority on entertainment software (GarageBand and iMovie).

UPDATE: So I sent my laptop to a Lenovo Service Center already. The technician told me that this model is facing alot of issue due to bad engineering of cooling system He told me that laptops generally should be around 50C but my laptop heats up to 60C even when left idle so it might be a thermal issue after all.. He said my laptop's problem is under warranty but it will take minimum 3 weeks to a month due to the warranty claim procedure of Lenovo with no ETA He promised to update me weekly regarding the status so hope everything goes well (not going to expect him to do so anyway )

But an important thing to take note, he notified me that my laptop hinge on both side is damaged, with both screws missing, 1 gear missing and another gear dislocated. I asked my retailer and they said they have not tampered with the laptop nor damaged the laptop in any way while it was with them as it was under warranty.. So i suspect it was damaged before it was even purchased by me.. The technician said that external damage will not be covered under warranty.. It's not a big issue but I'm worried with extended use it might damage my screen cable and Lenovo OneKey recovery button located near it, causing my laptop to have a malfunction screen and OneKey button.. I have uploaded the pictures for any Lyn forumners reference.. Anyone that has the same model as me please do check your laptop now to see if the screws on both side are intact and tightly screwed (loosely screwed but intact is an indication of it being broken). This kind of defect might not be caused by you but it is not covered under warranty.. so any dispute will have to be with your retailer or Lenovo itself if you purchase it directly from them..

A brief google search about this issue turns up with alot of similar problems from Lenovo forums itself.. I left some links here for reference regarding this hinge problem...

https://forums.lenovo.com/t5/Lenovo-P-Y-and...en/td-p/1587738
https://forums.lenovo.com/t5/Lenovo-P-Y-and...ty/td-p/1761609

Not only that, he said my laptop might be tempered by someone and therefore caused the hinge screw hole to be broken. He showed me the Lenovo sticker is still intact which means my laptop has not been tempered with, but it was poorly paste and exposed the screw so it can be unscrewed without damaging the warranty sticker. I told him it's not my problem that Lenovo itself paste the sticker poorly that is making my warranty claim difficult but he told me there is nothing he can do about it.. and my warranty might be void if there is proof that my laptop has indeed been tampered with causing my crashing issue to be void of warranty and subject to a fixing fee (nothing to worry about unless my retailer lied to me about not touching the hardware, which I will bring this dispute to them).

Will update you guys on my status and trying my best to reply everyone promptly on a side note can anyone recommend any laptop service center that does thermal paste reapplying and cleaning of the heat sink around Klang Valley? Currently using an old HP Compaq Presario CQ40 and it warms up to around 75C even when left idle.. and goes up to 105C before throttling down performance to cool it back to 95C while playing Dota2 at the most minimum graphic settings..

good feedback.. which model is this? y400 bla3.... so that, this model can be avoid at the moment.. else will be same issue in the future. and where you buy this notebook? it could be someone tempered the notebook.. like third parties supplier.. jz like.. the model shud come with 8gb ram (4gb x 2) but they remove 1 ram... then.. it will b 4gb ram only.. want upgrade... spend extra money.. some people.. will did this...

3 weeeks to 1 month... wtf.. tat is so long...

i mean good feedback is.. his good explanation.. feedback to this thread.

I know la... just shock by the period it takes to repair... dell make 2nd trip I already jump the gun Jor..

3 weeks to a month? wish you luck bro... Y400 is known for heating issue and im surprise that the technician being that honest and tell you "due to bad engineering of cooling system"

btw i recalled there is one thread about lenovo quote for 1k+ to fix the hinge

Hi TS, can I know which SC u sent your laptop? Yes this model indeed had bad cooling system since lenovo release this model and a lot of bad reviews of the cooling system. Even u go to reapply thermal paste and cleaning up the whole laptop, its still unable to solve your problems, when compared your laptop with mine, your max temperature still under "safe" level. I've assume the root isn't from your thermal issue but since you had sent your laptop to SC, you can just request them to reapply. Keep in mind SC only will use some budget normal thermal paste, it not really have any significant temperature reduces. IMO, your laptop 60'c at idle is quite normal for this model, mine went to 70'c still working well.

IMO, the SC claimed to take minimum 3 weeks to a month to repairs/services is really ridiculous for me. I had sent my laptop(y400) to 2 SCs in a month. First time is unable to power on, sent to Plaza Berjaya SC, take 7 days repair. Second time due to the RAM slot problem cause the laptop unexpected shutdowns, sent to Seremban SC, take only 5 days to repair. Even when i asked the stuff at Plaza Berjaya about ETA he claimed only need around 5 working days to done the work, he said I can always call the SC ask about the progress if I want to push them.

About the hinge issues and screws missing I think is DOA. Did u had checked the laptop completely when u purchase the laptop? BTW last time there is a forumer also said about his hinge cracked issues. You can find it out at Lenovo related thread I can't remember which thread and how long ago.

if you main reason is video editing, then indeed there's a point for going MAC, but problem is how much would u be paying for it? As I recall a MAC with a decent graphic card would easily cost 5k


Some technicians are honest about the flaws etc when u send in to service. If you service gonna take 3 weeks to a month, normally it means you're sending in to a smaller SC, and they send your laptop to their main SC to repair. Best to just ask them for the main SC near your area, go there yourself and repair it. Last time my Asus tablet took only 3 days to fix a main board problem, when the sunway pyramid branch says 2-3 weeks time.

Honestly cleaning heatsink and repasting is something u can easily do, just google the disassemble video of your laptop, be very careful and follow exact instructions and you'll be safe. just research around what's the best thermal paste, have 4 hours to just slowly do everything, and enjoy your laptop with much cooler temp

last time I claimed warranty on y400 faulty mobo, it took a week or so.

btw, replacing the palm rest + mid bottom case coz rm8xx pre-GST and it took weeks since the parts are coming from China.

y400? that was me.

Thanks! I only know is Lenovo y400 This model is replaced by the Y50/70 already and no longer in production.. Generally I think Lenovo laptops might face this issue.. Bought it in Lowyat Plaza.. Omg you said something similiar to my experience.. I bought this laptop with only 4gb ram and I paid an additional RM200 to upgrade to 8GB..

Yea but according to him is standard procedure due to claiming warranty and it seems normal.. I also shocked by how long it's gonna take.. was expecting 2 weeks..

Haha thank you Just wanna share my experience here so that other Lyn forumners won't have to go through what I'm going through now.. or at least know how to handle the situation better

Haha why you keep on promoting Dell.. you're a sales agent for them is it

Yea it's gonna be Hell on Earth for me.. Yeah he's actually quite honest and when another customer asked him about which laptop is the best in terms of quality (he was entertaining another customer at the same time about her faulty Thinkpad screen) and he said Apple Macbook Walao so exp..

I sent to the one in Puchong.. I should have did some research before buying.. I only bought it cause it was a great bargain.. regret now They say they will do it as a standard procedure Wah seems that my laptop's thermal issue is still okay.. Wah so fast? He said the same to me too about calling to ask about the progress.. and that it takes 3 weeks to a month because they don't know what's causing the crash and need time to determine what's the issue, and then submit a warranty claim to Lenovo HQ, and waiting for the specific part to be delivered to them and so on...

DOA = Damaged on Arrival? I was excited that time and didn't bother much as it seems new.. so didn't really expect 2 small screws to be missing.. Is he the one that commented below?

Yea budget is currently tight so I guess I will have to deal with this y400 for now.. Yup their service centre seems small as it is a small office area on the upper floor of the shop lots. But I already submit it to them, so I guess all I can do now is wait..

Okay but currently don't dare to do anything with this old laptop as it is my only laptop left with me that is working.. If this one dies I'm gonna live a barbarian life for at least a month..

Wah so fast? What was your problem?

So expensive.. Its like spending almost half of the laptop price to just fix that 2 stupid screw hole

Do you still remember the title of your topic? Or can you link me to it? If not I can just search it up myself.. Thanks

I do sell dell n I do angry when they hv to come 2 times to fix 1 error... we pay extra for the service dude.... I did wrote a 1 full page complaint when they send wrong parts for my m17... totally not wat I request... claim max after tat... my m17 every parts claimed other than casing... hehe

sometimes... need check at the broshure/website.. cz the package shud be similar.. so if something lack... there is must be suspicious specs provide by the shop. usually lowyat have a lot of 3rd parties seller.

appreciate that...

unable to turn on.

dey, nowadays can find laptop with on par y400 performance @ rm2499?

Wah.. Full utilization of warranty

Yea.. learn lesson d Then should go to official retailer to buy? But they are more expensive right..

Wah, caused by heat issue? What laptop?

some are cheap... some like garage sales seller offer better deal

If not y I buy dell. I am paying extra 15% for this OK... every 6 month ask them come overhaul n clean for u.. hehe

We have the same issue of y400.. Hehe..

7447 is currently the budget gaming laptop on par with y400.

unstable power source + using w/o battery caused some short circuit.


7447 dell? gtx 850m but similar performance?
price is higher than rm2499 lorr.

But I prefer physical store cuz if got any problem can easily refer back to them first..

Extra 15%? Wah got such service as overhaul and clean the laptop when needed? so good de meh

The power brick faulty? Wah like that also can short circuit, I usually use without battery to keep it in pristine condition de.. but if I play Dota2 on battery without power source it will lag like crazy until I set all graphics to minimum.. I suspect is underpower cuz using battery

Dell Inspiron 7000 series? If want on par or better then is RM 3k+ d leh...

power source = power outlet lor.
we still have 3rd world quality electric supply here.

p/s: that's why I paid for the casing replacement.

Wah is power supply issue then how to use laptop Haha chill brother GST will move us to 1st world country faster than 2020 But still the casing itself is still too exp... rather use till spoil and then change laptop since 2 loose screw won't really affect much if handled with care..

Dell price 15% extra compare to other brand. No such service 1... but if u know how to use the onsite warranty service... anything is possible

400 for me hinge last 6 years.... Now my next 2 laptop only acer forever.

Rosak straight dump rite... good choice.. haha.. I did tat when I was single too... throw Acer really not much pain... most of them spoil after warranty...

PC got 2 before..
