Windows 10: Issue with Laptop turning off after applying new thermal paste

Good Afternoon,


I decided to clean out my laptop of dust and install new thermal paste after several years of use. I've done this before with other PCs and laptops with no issue. I was able to reboot fine, then after about 10 minutes the laptop just turned off randomly. I was concerned, but upon turning the device back on I've run into my issues.

• The laptop will go to the Windows login screen and stay there with the custom background I picked. If I hit 'ctrl alt del' to get to where I enter the password, the password begins typing itself slowly one character at a time. My keyboard doesn't work at this point, I can't click backspace or if I hit a key nothing registers. After it types 4-5 characters the device shuts off
• I can't get into BIOS for the machine, as it will turn off either before BIOS loads or right as the BIOS comes up
• I get to the startup repair, however the device powers off when I go to start it where it asks for the account's password

I thought I may have mis-installed the cooler/fan and the thermal paste, however I've cleaned it now 3 different times and even bought new thermal paste in case the prior tube was old/expired, but still no luck. Is this a software issue? I am not sure if the device is broken or if it's a software issue. My thought is something is affecting the fan/heat sensor forcing the device to shut down, but I am not seeing anything on the board which looks fried/broken.

First time placing a thermal paste.

Agreed. Looks like the OP was looking for better temps with AS5 and applied:

• The cooler wrong
• and/or Tim wrong

Now the thread takes a turn Jester.

 

Best thermal paste

Most decent thermal paste is about all the same (1-2 degree difference). Without knowing the two listed, (I use MX-2), I would suggest going with the one that is non-conductive.

 

Thermal Paste Questions

For the Core i7, I suggest drawing a 7 with thermal paste. For the core i5, a 5.
