Your average laptop comes with a 300 cycle battery or about 18 months. Not only do cycles matter but age. If the battery is uses daily I see such failures in all of two places. (Battery and motherboard.)
But here's the real problem. Owners don't want it to be any of those issues. They always hope for it not to be that even when you present them with the life span of the battery. Many didn't grasp this until the next year or two after they use the battery all the time. After they get to buy a battery that's when I find most to have learned to keep it on AC as much as possible.
Beyond that, no shop I know will let you use a battery for a test to see if that's it. If you need to know why it's simple. 1. If you did let them test with it, they would not want that battery but a new one. So the shop would have to have 2 batteries. 2. It happened at a friend's shop that the customer claimed the new battery was theirs and threatened to call the cops or sue. Sadly this meant the end to stocking batteries or letting folk try out batteries.
This morning as my laptop was plugged in and charging, I noticed my battery power seemed to be draining, but it showed it was charging. I unplugged the AC adapter and plugged it back in, and then it didn't show it was charging and the lights weren't on.
I tried unplugging and plugging it in, checking connections, and using different outlets but I just couldn't get it to work.
I brought it to Radio Shack and they tested my AC adapter for me and told me there isn't a problem with it. I plugged it into my laptop then and the charging lights were on.
I went home and plugged it in, and the charging lights were on again. I turned the computer on and noticed that the battery power was draining, even though it said it was charging.
So what I've got is an AC adapter that apparently works, but won't get the laptop to hold a charge, PC Health Monitor told me that my battery was fine, and my laptop runs on its own without the AC adapter plugged in.
The lights only show that the laptop is charging sometimes (most of the time it doesn't) and even when it shows it's charging, it appears only to drain more. Is this a problem with the soldering for the pin coming lose? What could it be?
I'd really really appreciate any help, as I use the laptop for full time school and I need it repaired as soon as possible, but I don't have a lot of cash to go trying out new parts (but from what I understand, it doesn't seem to be the battery itself or the charger itself that's causing the issue).
By the way, it's a Toshiba L505, not under warranty anymore, and the laptop itself works perfectly fine when on (just a charging issue I'm having).
