Power Issue With Battery or Power Adaptor??
My Wife's employer gave her a notebook (Toshiba Satellite Pro A300) that needed a new O/S and HDD. For the price, we couldn't go wrong and I had a spare drive laying around.
When I initially turned the system on, everything appeared to work. Bios loaded ok and it booted up to the install disc. However, at the beginning of the installation, the system would shut off. I tried this a few times and used a different version of Windows to install with the same results. I then took the battery out, and was able to get a complete install with only the power adapter plugged in. Everything runs good, honky dory. Shut down, installed the battery. Started back up - pop, shuts off during the load up. Bad battery perhaps?
I thought I'd mess around just a bit, I decided to use the battery itself to run the system. It had some charge and I was able to login to Windows. I played around, connected to the internet, no problems. I then decided to plugin the power adapter to see what would happen. From what I can tell, the system switches back and forth between the power adapter and the battery. The screen constantly flickers as well as the power adapter LED (both flickering at the same time, the screen dims) as it switches between the power sources.
My question (finally) is it a bad battery, a bad power adapter or a bad motherboard? As stated above, the system runs fine on either the battery or power adapter, but flickers with both sources connected at once. Any help/thoughts in solving this issue would be appreciated, thanx =)
