I have a Toshiba Satellite L25-S121, after about one year, my battery started to really lose it's longevity. If it ran about 15 minutes, the battery indicator would beep and a minute later, shut down the computer. As nfox513 mentioned in a post 3 days ago, I did the same thing and bought a new battery. It charged one time I think, ran for about 2 hours. I was so thrilled. Next, I plugged everything back in, and now it will not hold a charge. The battery charge (far left amber light) indicator light will blink the entire time computer is turned on and plugged in. When I click on the battery charge meter on task bar of screen, it reads "0% remaining (charging)" as the progress. If I unplug power cord, computer shuts off immediately. I searched Toshiba site and cannot locate any kind of update BIOS for this problem, nor anything other than "step-charging" instructions. That does not help, because the computer shuts off right after being unplugged, within a second. What do I do? please reply here or feel free to email me at rob noell 3 at yahoo dot com with any tips you might have. Thanks very much!
