G510 Overheating - How Do I Reseat the Heatsink?

2015-04-01, 23:13 PM

It's been four months since I got my Lenovo G510 and I recently noticed it's running hot. Idle core temperatures are around 49C and any kind of load on the system brings it up to 90-100C within a minute. Room temp is around 23C.

 

I'm pretty sure I need to reseat the heatsink. Any advice? I looked for a tutorial and couldn't find one.

Solved! See the solution

Good day.

 

Have a look at your hardware manual: http://download.lenovo.com/consumer/mobiles_pub/lenovo_g400g500g405g505g410g510_hmm.pdf

Removal and installation of the fan/heatsink assembly starts on manual page 64. It looks like a complete tear-down job to me as the system board needs to come all the way out to access the parts.

 

You may wish to try blowing out any accumulated dust from in and around the assembly to see if that makes a difference, first. It looks like you can do that by removing the lower cover. Best to hold the fan blades stationary while doing that so as to not potentially damage the fan bearings. If that doesn't help you could do the more extensive work required to apply new thermal compound.

 

Edit to add: If you're under warranty, a call to Service may be best, as a start.

 

Hope this helps a bit.

Regards.

Oh wow. That is a lot more intense than I thought it would be. Thanks for the link.

 

I am within the 1 year limited warranty window. Is this sort of thing covered? Is Lenovo good about their warranty service or should I try to do it myself?

 

EDIT: Ok I just saw your edit to call support. I'll try that.

The intensity of the job largely depends on how comfortable you are working on small electronics. These newer machines have smaller/thinner wires and connectors, which take due care not to damage. Since your machine is under warranty, the complete tear-down scenario may be best left to Service.

 

Blowing dust out of the fan area, though, should be pretty easy and since pulling the lower cover looks like it would give adequate access, I think I'd try that first. You might be surprised how much dust accumulates. As I mentioned, just keep the blades stationary and blow the dust outward through the exhaust vents.

 

If that doesn't help much, a discussion with Service (info below) can be the next step.

 

Regards.

I just got off the phone and I think I'm going to try sending it in. There's a secondary issue of wifi connectivity I'd like to have looked at anyway.

 

I was told it'd take 7 business days and the service center is in Texas so that's not too bad. I just have to pay for shipping.

 

Thanks for all your help!

Update: I got my laptop back from the service center and the fan is a lot more quiet but the high temperatures remain. I'm not really looking forward to paying another 20 bucks to ship to the service center again but I don't know what else I can do.
