Good evening all.

I'm currently replacing the thermal paste on my partners laptop CPU. The laptop is a Toshiba Satellite c55-a-5100. It comes with integrated laptop graphics? (Mobile Intel® HM76 Express Chipset / Mobile Intel® HD graphics with shared graphics memory) but I noticed that the GPU does not have any thermal paste on it. GPU is circled bottom right of the image. The casing doesn't have any sort of heatsink/pad on it either for the GPU.

Is it okay to apply thermal paste to the GPU or best to leave it alone? Thanks.

If the heatsink doesn't cover it, there is no point. Are you sure that's the GPU? iGPU is part of the CPU die, and a dedicated GPU will definitely have some form of cooling. I suspect that is probably the 'chipset' chip.

True. Yeah I have no idea to be honest. Looking under the hood of a laptop is relatively new to me.

A lot of heat comes out from that area when the computer is under heavy load and when I saw another chip, I just guessed thatit may be the graphics. But considering the fact that it's integrated, your comment makes sense.

Google the numbers on that chip, you'll soon find out what it is.

Chipset that provides the following for the system:
A second generation DMI link between it and the CPU
8 PCI-E 2.0 lanes
2 SATA 6gbps ports
4 SATA 3gbps ports
4 USB 3.0 ports
8 USB 2.0 ports

Looks like I'll just do the CPU.

Thanks for your help
