I have a power problem with a Toshiba A75-S209. It had been operating properly until a week ago. It suddenly won't run on AC power; it keeps defaulting to run off battery even when the AC power adapter is plugged in. The light on the AC power adapter comes on, and the left light on the front of the laptop comes on (signifies that the laptop is plugged in), so it is "seeing" the AC power connection.
When plugged into AC power with the battery installed, the battery will charge when the computer is turned off, but when the computer is turned on, it runs on the battery until the battery dies and the laptop shuts off.
With the AC power plugged in and the battery removed, the laptop won't even turn on. It sometimes runs for as much as 40 seconds, but as soon as it tries to turn on the screen, the light signifying it's trying to access the battery will flash orange then the laptop will turn off. Sometimes it only takes a couple seconds before this sequence happens & it turns off.
Have tried booting it completely then shutting down normally, but that doesn't change anything.
Have used a compressor to blow the dust out, but no luck.
Almost 2 years ago, I took it to a service shop to have them repair/solder the connections to the power jack, so am already familar with that problem. These symptoms are different. Yet, if that connection has become partially compromised, I guess the laptop might be accessing the battery to compensate for the limited power?
I don't know. Maybe my ex-wife is right & God just doesn't like me. ;-> I sure would appreciate any insight into the problem or suggestions on resolving it. I'm about one step away from using this laptop to play frisbee golf with my trash can. Thanks much in advance for your time.

Hi,
Your laptop:-"Toshiba Satellite A75-S209" is compatible with the Windows 7 operating system.Thank you for your time and best wishes for your effort.
Take out the battery and try booting the machine on AC power only. If the machine boots up then let the operating system load up, the shut it down. Remove the AC jack and put the battery back in again, then power it up.
If it boots all is well if it doesn't then there could be a problem with the battery.
If the laptop won't start on AC power, what you could do is remove the system memory, clean the brass pins and the slots and then re-seat them/it.
