y570 issue

[AndreiC]

Hello,

I have bought a new Y570 laptop last October to serve as my computer over the next few years, but i was very dissappointed by it just after several months. Besides working on it, ofcourse i have tried some gaming. At first i played Crysis 2 and Call of Duty MW with all options on high detail and they worked very well, just as expected. But then i tried NFS-HP and CoD MW2 and i started having problems (sudden stalls - 1-2 seconds -, colour distortion up to a point the computer froze and had to reboot or on several ocasions ctrl+alt+del worked). I tried "Star Wars: the old republic" and it only worked with the help of "throttle stop" programme... without it i would't have been able to play it even on lowest detail and it stalled anyway in some cases. It appears selecting low details on any game now, does not help anymore, as it starts stalling at some point and frame rate goes down. What is most interesting is that it starts behaving very bad as it heats up and graphics card is turned on. For instance, if I start CoD MW2 now on full detail, it runs smooth for about 5 minutes, then frame rate goes down. Once, it heated up so bad that it shut down itself only by working on AutoCAD. I have read a lot of threads about the Y570 on this forum and searched on the internet. Disabled core parking, put the energy management on optimizing battery runtime (yes it does have that glitch with plug-unplug. it seems it works a LITTLE better when it is unplugged), tried throttle stop (better results but problem not solved), installed drivers from the Lenovo site, installed latest graphics card driver... none did actually work. It seems like this laptop is somehow 'aging'.

Is this problem known by Lenovo or not? I saw a lot of people complaining..  but no actual help..

I am very dissappointed since I paid a considerable amount of money on something that does not deliver what it promissed or should have delivered. What is it to be done? Send it to service check-up?

Processor: Intel Core i7-2630 QM CPU @ 2.00GHz

4G RAM

64-bit operating system

Graph card: GeForce GT 555M

There is a post on the forums here, about how much thermal paste comes on the y570. Too much paste collects the heat and throttles down the cpu/gpu causing the stuttering, ive changed the upper thermal limit in bios to 90c insEad of the 85 it defaults to, and redid my own AS5 thermal paste. along with throttlestop, all my issues are gone. Hope that helps http://forums.lenovo.com/t5/IdeaPad-Y-U-V-and-Z-series/Y570-Thermal-compound-bath/m-p/671361

hi guys

nearly the same issues with overheating(with i5-4230 and rapidboottechnology) ...

luckily my pc never shut down til now, but still i think its just a matter of time until my laptop will be crashed due the high tempreatures ...

one big problem i discovered, is that my notebook even stays warm after i exited the game i played before - that means i had around 55 degrees (cpu)  after i closed every programm i could.

i bought my y570 christmas 2011, and there i think i played skyrim without any stuttering.

then i had hard lags while playing the witcher 2 and shogun 2  in march (2 games with high performance needed), so i read some threads in this forum and then simply cleaned my fan.

For about 3 days i got no issues with overheating, then it started again. so as the next step i elevated my notebook with some pcgame-boxes (cuz they have all the same size), it reduced the overheating problem, but unfortunally it didnt solved it.

then i installed the newest betadriver (301 or so) - as a result now my gpu dont get temperatures above 95 degrees - mostly around 87 while gaming.

before it hit the 100 degrees everytime after i played 2-3 minutes.

but still my cpu has high temperatures

- the one core max. 95 degrees - the other 98 max. 

my avs (norton) show that the cpu even hit the 100 degrees - no matter what - its way too high.

not using my cpu isnt a option, cuz i bought the y570 for playing games.

its german, but i think u still understand the crucial facts.

btw. it also shows a high ram-usuage - but there stands that just 1.4 gb is used. ( i should have 4gb - so atleast 3 usuable)

you know why?

i would rly aprpeciate some help!

muliphen, did you take out your fan for cleaning? what paste have you put on your CPU and GPU after you cleaned the fan?

[zitnikp]

Did either one of you guys clean the fan?

[muliphen]

thx for ur response!

yes i cleaned the fans - but actually i dont know how to take out the fan for cleaning.

i simply unscrewed the cover of the notebook and then blew on this cover.

finally i took a handkerchief and cleaned the fan as best as possible.

regards muliphen!

You should try to get a can of compressed air and then hold the fan in place and spray the air onto it from certain distance(like 20 centimeters) and that way, it would be properly cleaned. If that doesn't help, you should consider getting a thermal paste replaced(if it's in warranty, a lenovo service can do it for you, if it isn't though, you can do it by yourself).

Hi, some useful information regarding fan and heat-sink cleaning...

good Luck... Zehn

thanks for the link, going to try it out.

@zitnikp i didnt tried to clean my fan with compressed air, cos i was afraid of destroying it. 

do u think i could clean it with a hairdryer?

i bought the y570 4 months ago, so i think it is in warranty, but i read in some threads that the most y570 has problems with overheating - so almost nothing would probably change. also i have no idea how fast the lenovo support is.

do u know if it is useful to send the laptop back?

regards! muliphen.
