My refurbished laptop is about 1 month old. It is Lenovo ThinkPad T480s. Recently, the laptop base at the top side will get hot easily. I need to shut down and wait maybe 20 minutes for it to cool down.

May I know how can I solve the overheat problem? I am afraid it will burn the motherboard.

Thank you.

Thermal paste hardened. Need to replace it.

Also, clean the CPU fan too. Thin laptops usually have very thin fan but lousy at thermals and will fail overtime.

I tried to open all the screws at the base of the laptop and unable to take it out, although can turn the screws. Then, I opened the cover to take a look. All the screws have a thin layer thing blocked me unscrew. In this case I cannot clean the fan and apply thermal paste.

The problem is I cannot take out the screws. There is a tiny layer locked the screw. I can turn the screws using the screwdriver but cannot took it out.

Go to youtube search your laptop model and watch those video and learn how to open the case.

If you're so inexperience on computer DIY, take to shop and pay money.

Open the casing is the first step, next you need to uninstall the fan, heatsink, correct way to apply thermal paste, you need to watch a lot of videos.

Or take it back to the shop you bought it 2nd hand and ask them to fix it. you pay for the thermal paste.

I assume your refurbished laptop purchased should comes with warranty with the dealer at least one month.

Advise return to the dealer or ask the dealer top-up for you to send to service center for service.

If you're not confident in doing it yourself, I suggest you go to any computer repair shop to get it done for you by the professional.

Replacing or reapplying thermal paste sometimes won't solve the issue if your fan motor spinning is weakening. Get a new fan replacement and reapply new thermal paste for your laptop probably will fix the issue more effectively. Parts are available at Plaza Imbi (DS Notebook, Faith IT, Rascotec or Laptop Depot).

I suggest you to replace the thermal paste, clean the CPU fan from dust and buy a USB laptop vacuum fan, this will help maintain your CPU temperature.
