If you’re opening up the laptop for all these replacements, you should consider replacing your thermal paste as well. If the laptop is over 5 years old, it may benefit from the replacement.

I’d recommend trying to find an ifixit guide or a video of someone else opening up the laptop online and reading/watching that first. Getting to the cpu is usually a little harder than RAM/battery.

If you did all that, it would really feel brand new.

Ok, but did the Chinese scientists even once stop to think about what an excess of clean, drinkable water would do… to the economy?
