So I got the lenovo ideapad gaming and it's been around 2 yrs so the fans are clogged and thermal paste has dried. Where can I get it cleaned and get the paste reapplied? I am looking for someone with good knowledge and experience not those illiterate mfs who will mess it up more. Pls tell me.

So I bought the 20k mah variant today, it's been like 5 hrs since it's on charge but only one led is blinking. I am using a oneplus 80 watt charger.

I tried charging my phone and it charged as expected.

But the Powerbank itself is not charging.

What to do? Should I replace it or its the optimal speed?
