A while back there was a power outage at home and the original AC adapter of my Dell N4010 stopped working. I replaced it with a new generic power adapter (I couldn't find an original anywhere where I live). The power adapter worked for a while, and it still powers the laptop with no issue, but the battery is not charging to full. The battery is a replacement one I got about a year and a half ago to replace the original that shot after working for about 5 years. Here's my original post about this issue. I took the laptop to the IT shop that sold the adapter. They plugged it and the adapter worked fine and the battery seemed to charge as well. They checked the voltage issues and whatever and said everything is working fine. I had run a battery diagnostic, which showed the capacity at 44%. I asked them if I should replace the battery and the IT guy said there's no need. Back home the charging issue persisted even after I changed the power outlets. I thought it was an issue with the home outlets and have been meaning to call an electrician. The problem is, this morning the battery indicator LED started flashing orange. When the computer boots it says "battery not identified and is not charging." I went ahead with the boot up and the computer works fine. The battery is at about 60% and it says "plugged in, not charging." I'm not sure what the problem is. Is the A/C adapter not working as it should? It's a Chinese-made replacement one, the only kind I can find here. It powers the laptop, but doesn't charge the battery. Could it be an outlet issue? But it's the same when I changed the wall sockets (two different power lines). Or should I buy a new battery? I've been reading online some threads about this and some people say BIOS could be a problem too. I have a Dell A10 2010 BIOS. I'm so confused. Can someone please help?
