I have a Toshiba Satellite L775d-s7332 17.3" laptop. The old battery (Model: PA3817U-1BRS) is bad, but when plugged in, the laptop turns on but not charge. I bought a new battery same model (aftermarket) and tried it but the battery light flashes about every 5 second. I return the new battery and bought another 1 and same results. The laptop works fine with only charger and no battery or with charger and old bad battery. The latest BIOS on the laptop is installed version 1.50. I can't downgrade the BIOS because the laptop wouldn't allow me since it does not see the battery. Any suggestions?
