I have Toshiba Radius e45w-c4200x which I bought almost two years ago. Suddenly it can not be turned on, even if the battery has fully charged. I never put the battery overcharged and it works very fine with almost 6 hours life at the day before yesterday. But, the laptop is still on the best performance when connected to the electricity. The battery also indicated that it is 100%. Any suggestion would be very valuable for me. Thank you very much.
It could still be a bad battery. They can give false power readings when they are going bad. Also, another sign of a battery going bad is it not having enough power to turn on the device, but will run it once it is on. I would suggest a new battery.
