I have a Dell Inspiron 8200 laptop that I purchased on the secondary market last year. Recently it has begun having two problems:
1. It makes an annoying screechy whine on startup. It's not the fan or the power supply.
2. It identifies that the battery is low even when connected to outlet power and switches itself off. I've purchased a new battery to no avail. It won't recognize the new battery to charge it.
I'm thinking it's probably not worth it to try to get the thing repaired, but I thought I'd post this on the off chance that someone else is familiar with the problem and it's something relatively minor.
