windows 8.1 - Lenovo Ideapad z510 crashes when connected to AC power but works fine with the battery

I use a Lenovo Ideapad z510 running Windows 8 x64 and earlier today, during a snowstorm, power went out. Later, power came back and I got on my computer. As I was using it, I — idiotically — lightly smashed my hands on the keyboard and my computer crashed.

I could only turn it on when running off of battery power only. Trying to turn it on with the plug in would either:

1. Not let it turn on.


2. Crash the computer a few seconds after turning on.

I have tried draining the battery then turning it on with the plug but it doesn’t seem to help. Running from battery works fine, however, I am having issues charging said battery. One of two things is happening right now:

1. The battery is not charging at all, even when plugged into computer that is turned off


2. The battery is charging very slowly when plugged into computer that is turned off

Any ideas?

Answer

Edit: Careful with this. I think it's only a short-term fix...

I fixed it and wanted to post the answer for others. Here is what I did:

This may not work if your laptop cannot run without a battery. If that is the case, you may try to follow the steps but skip step two. I do not know what this will produce, however, as I have not tried it.

1. Open up your laptop and unseat the battery. This simply means to disconnect it from the laptop, not necessarily to take it out of the case itself.


2. Start up the laptop plugged in but without the battery. Wait for it to finish booting up; make sure nothing unusual happens.


3. Shut it down and then reseat, or re-connect the battery


4. Start up the laptop.
