Re: overheating and dancing pixels in new mainboard

@yigit, is it confirmed that problem is because of overheating, because in that case i will call customer care and take my laptop to service center again tomorrow for checking heatsink etc.

 

Also, i was reading,  http://forums.lenovo.com/t5/IdeaPad-Y-U-B-V-and-Z-series/IdeaPad-Y560-heat-issues-with-BIOS-71/td-p/... , and found that BIOS v 71 is causing a lot of heating problem and downgrading to v 59 is much better. Is it so?

Re: overheating and dancing pixels in new mainboard

not for bios 71 issue, but for overheat issue, i was thinking of taking it to service center.
Also, yes, i did a clean windows installation from my recovery disks.

Re: overheating and dancing pixels in new mainboard

@yigit, i took my laptop to the service center. They did some repairing to the laptop and here is my result!

 

Well, i bought a cooling pad for my laptop. Played game for around an hour, laptop didnt shut down. Also, what i notice is that, upon light usage, GPU and CPU temps ~50 * celsius. Upon playing game, GPU temp is ~75-80* celsius, which is very satisfactory. But, CPU temp shows ~ 90-95* celsius( even 100+!!), which worries me a lot. Also, as soon as i close the game, temp plunges to ~65-75* celsius in a second!

 

How is it possible that CPU temp plunges by 20-25* celsius in a second? Is it normal? Is it even possible?

 

Reply soon!

 

Regards

Pranav

Re: overheating and dancing pixels in new mainboard

run task manager and check processes tab for high cpu usage.
which application/software causes?

also, check your bios version.

Re: overheating and dancing pixels in new mainboard

@yigit, i checked for processes and found that the game, James Bond or GTA 4, which i play takes up lots of memory(570k), and thereby increasing CPU uasge to 70-80% and causing overheat.................

 

Regarding BIOS, I have made a surprising discovery! Recently, i had dancing pixel issue on BIOS 54, so i upgraded to 71, and the problem solved. BIOS was successully upgraded and was stable. But, today again this dancing pixel problem showed up and i was shocked to find that my BIOS downgraded to 54 by itself! Hows that even possible?

 

Please help me!
