Hello friends,

Yesterday, my laptop began displaying the message "plugged in, not charging" and behaving strangely. Most notably, it is indeed not charging the battery; it gradually declined until it reached 9% charge, and hasn't moved since in either direction. My laptop is mostly for school use, and so during the semester is unplugged and replugged frequently; since the summer started, it hadn't been unplugged for a few weeks, but the other night I removed it to do some work, and when I plugged it back in I got the error message. Upon startup, I receive a message telling me that the power adapter could not be identified, and this could cause problems. In BIOS, it lists the AC adapter as 'unknown.'

So, I've been trying to solve this problem for most of today, and I've tried quite a few things. I've tried:

- inspecting the AC jack and the computer's jack. There is no visible dust, bending, damage, or anything else obvious. It is not loose. It inserts fully. There is no obvious damage to any other part of the charger.

- Update BIOS. I did this before my computer fell below 10% charge. It did nothing.

- I've uninstalled the ACPI-Compliant Control Method Battery driver and reinstalled it. It did nothing.

- I've cycled through all of the different power settings, etc. It did nothing.

- I've powered my laptop down, removed the AC cord and all peripherals, and let it stand for around 10 minutes.  This did nothing.

The only obvious exception here is trying another charger - I have one on the way and should receive it by the end of the day. Hopefully it's as simple as that, but I have a feeling it isn't.

Ok, so, is there anything obvious I'm missing or haven't tried? Anyone have any experience with this sort of problem and have a fix? Most people online say that replacing the battery didn't help, so I'd rather not spend a bunch of money on one. I've heard it could be the mobo, but there was no electrical spike or event that could have caused this sort of damage; while it's possible it's a coincidence, what are the odds the part of the mobo that interfaces the charger and battery failed at the exact moment for no particular reason?

Lastly: currently my laptop works when plugged in. This is good! But it works slow to the point of being basically unusable. I think this is because it believes it is running on 9% battery, and conserving resources.  This **bleep**. Is there a way for me to bypass this and have it run directly off AC power, regardless of my ability to fix the rest of the problem?

For simplicity, I've attached my sysinfo.

Thank you for any possible help!
