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

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

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

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 

[attachmentid=4426241]

gpu max 98'c 

edit: note the max temp

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 

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.

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

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.

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

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)

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.

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.

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

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...

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

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

Wah.. Full utilization of warranty   

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