It sounds like the backlight or an inverter board on the television may have failed. Check your warranty status on the television to see if you can get it repaired by the manufacturer for free.

This is usually caused by a bad battery. Sounds like both batteries are not working properly. They may still hold some charge, but they are wearing out. After all, they are batteries, and bateries wear out. Keep in mind that some batteries are better than others, even though they may be the same brand, some will hold a charge longer, and some wear out faster. I'm on my second new battery in a year and a half on my Dell, the first held a great charge but wore out after approx 8 months, the one I'm using now still charges fine but only last about an hour and 15 mins.

Hey,

there is a 3 volt flat battery inside the computer, it in most cases clearly visible.


Replace it with the same type of battery, then adjust the clock in the system setup.

All done, all fine.


Let me know if you need anything else.

Thanks,
Ekse

This is a common problem with the Acer Aspire one. Apparently, the BIOS needs to be flashed using a flash disk with the required files.

Unfortunately, the files are not available at any website but you can take the Aspire one to any Acer service center and they should be able to flash the BIOS for you free of cost.

Take the battery and power supply out and hold down the power button for 30 seconds. This will reset your hardware settings. Your backup battery isnt your problem. Does your battery light turn on when charging? Does your keyboard lights light up when it runs for a second (try pressing caps lock)?
