Only a few buttons are defective and the USB plugs are a bit loose, so that contact is quickly lost in the event of small vibrations. Otherwise everything fits. The new price was 220 euro 3 years ago.
I don't even know what to do with it. What is the most profitable way to get rid of the notebook? Sell defective? Or would it be more lucrative to have it repaired before selling it? Or a completely different suggestion?
Sell as defective… If the thing only cost 220 euro 3 years ago, then it wasn't a premium part and is now generally worn out. When it comes to having it repaired, you're easily so busy that you can buy a new one.
I expect that with a lot of luck you will find someone who will give you 50 more for it. But rather no… These should only be hobbyists who believe that they can fix it themselves cheaply or need certain parts of it as spare parts…
for such a shabby low budget device, I would maybe make a zwanni loose. But no more.
