IdeaPad Y560 shuts down in a few seconds during startup

[mvk94]

Hello,

IdeaPad Y560, Core i5,  Win 7 Home.

Since a couple of days I am running into this issues where my y560 shuts down while booting, within a few seconds.  It boots completely only when the air conditioner is on and the room temperature is around 21 Degrees C / 70 F.  

I saw this blog - http://www.lenovo-laptop-reviews.com/lenovo-y560-heat-problems-solved.html  and cleaned the clog.  Now that area is clog free.  

Yet it won't boot unless the room temperature is 21C / 70F.  I have my exam next Friday and need the laptop desparately.  Can somebody help me.  Please. . . . .   

Madhu.

i used to have this prob too, and i think it somehow related to the cooling system and graphic card, i tried everything from unistalling prog and reinstalling windows but got nothing then my laptop was broken

anyway i u shld return it 2 the factory or try to buy a cooler

Thanks man for your quick response.  I will get a cooling fan and see if it makes a difference.

Hi Madhu,

your problem seems to be related to heat, please have a look at this thread...

Thanks Zehn. Tht was my thought too and it is a heating problem. What i don't understand is can temp be an issue with in 10 secs from the time i press the power on button?  Laptop shuts down with 10secs.

Last night i cleaned the fan and the fins. 

With the room temp at 21C - 

CPU - 54

ATI    - 65C

Power management is already at  Optimize for battery Runtime

Hi Madhu,

hmm... temp would be a wee bit on the high side for idle but OK for light use,

but if dissipation of heat is interrupted components get hot in no time..

the heat-pipes are mounted with 4 screws to CPU and 2 screws to GPU,

check if these may have come loose, but please be gentle and don't over-tighten them...

is the fan running, do you feel air being blown out thru the heat-exchanger vent?

As a last resort may need to apply fresh thermal paste...

Thanks Zehn.  I really apreciate you responding so promptly.  I presently live in India, so will need to dig a lenovo shop out but I will do the thermal paste.  This afternoon i started my y560 without the airconditioner running and it booted.  The temperature readings are about the same as i reported earlier.  This time i have a laptop cooler fan blowing right below the laptop fan.  

I will let you know once i reapply the thermal paste.  

Thanks again.

MAdhu.

Yesterday I got in touch with Lenovo Support in India.  He made me update my SMBIOS and that resolved this issue.  You can get the update from - http://consumersupport.lenovo.com/ot/en/driversdownloads/Drivers_Show_3446.html

Thanks for your support and help.
