Hi

I have a Toshiba Satellite L850. My battery was wearing out so I purchased an original OEM replacement from PB Tech.

Plugged in, red light flashes, no charge. Try to boot while AC adaptor is plugged in. Wouldn't do it. Replace new battery at 0% with old battery at 0%. Plug in AC adaptor, computer boots.

Replace new battery at PB Tech, saying faulty.

New battery at home, try above steps, same result. 2 faulty new batteries?

3rd new battery. Same result. Currently plugged in with no battery, but as soon as I put any other new battery, other than my old worn out one, into the laptop it won't boot.

WTF is going on?

Many thanks

AJ
