Awkward: Compaq Presario C700 Notebook fixing itself?

edited May 2012 in Hardware
Today, when my brother unplugged the charger to the laptop, it didn't shut off, which should've since the battery was acting up, however, the laptop didn't shut off.

I was puzzled until I plugged the charger back in and the external IBM 2115-001 15" CRT Monitor (since the laptop screen is not working as of now) to see what was going on. The battery charger indicator was solid blue instead of flashing (meaning the battery couldn't charge in my perspective; according to the laptop); the battery started to go charge again... In addition, I cleaned off the battery terminals with my old, broken toothbrush (both the laptop terminals and battery terminals), which probably supposedly fixed the problem or the laptop is fixing itself O.o

Do any of you know that the laptop might have bad phases, or am I lucky I fixed the battery problem? Before I cleaned the terminals, the laptop would shut off after 10 seconds (a year ago), and after that, would shut off after disconnecting the charger (January, 2012). Then, the indicator was flashing, and said 1% available, not charging on the laptop (a few weeks ago). Then, today, the battery is starting to charge again. I think I saved $40 for a new battery, but the screen is still acting up. Do any of you know if the cable between the inverter board and motherboard is going bad, the board itself (external monitor still works on the fly), or a bad screen?
Cause I know a simple laptop screen cable is $5, the screen is $90, and the motherboard is $150 ($40 on this one site I found).

  • The only way to know if the cable is bad is to open the laptop up and have a look yourself.
