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» Click to show Spoiler - click again to hide... «
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...

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).

Initially feeling lazy to post an update regarding this issue, but this may help to be a future reference for people who faced similiar problems and wanting to know feedback regarding this issue. So here it goes.
During the duration of repair, I have called the service centre approximately 5 times, each time asking for the status of progress regarding the repair. Here are the details regarding each call:
Call 1: Requested additional parts from Lenovo HQ after diagnosis of the problem, awaiting reply.
Call 2: Requested replacement of motherboard approved from HQ, pending arrival of parts, ETA the same week.
Call 3: Replacement motherboard unit is faulty, unable to turn on laptop, 2nd request from HQ for new motherboard, again ETA the same week.
Call 4: 2nd Replacement motherboard also faulty, causing BSOD for unknown reasons after certain period of time, request from HQ for new motherboard, no ETA.
Call 5: ETA of new motherboard by the same week. (Specifically requested it to be done by the following week as my old HP laptop is having issues)
A week after the fifth call, they called and notified me that my laptop is ready for collection (June 11), which makes the whole duration of repair 2 months, a month longer than expected (may be absurd for some as typical laptop repairs only take about a week or so). Went for collection, checked for any damages, and left after signage of documents. The staff there handled the situation well with a smile and explained everything patiently.
However, the 4 little lightbulbs which indicate Power, Battery, Disabled Mousepad, and Caps Lock seems to be dimmer than usual, although not an issue but deserves to be pointed out.
IMO, I dare not falsely accuse the Lenovo Service Centre for making up excuses for the delay of my laptop repair, but the reasons given in all 5 calls seem oddly suspicious to me as it sounded as if they are making up excuses for the delay of the laptop. Therefore, my advise to anyone whom is dealing with Lenovo Service Centres to strictly request the laptop to be done in the shortest time possible, thus making it seem urgent and they might provide you with a speedier service.
Anyways, thank you so much for everyone who has been helping me through this, and I already bought a Macbook during the wait, thus making it bearable for me.
