I bought a used one-year old Panasonic cf-51 toughbook. When I try to run it unplugged, the battery will say how much power and how long it will run when I put the curser on the icon, but then the laptop shuts down after about 5 minutes. When I plug it back in, there's a message box saying the battery is critically low.
Please help, as this means I will not be able to use my laptop for business when no outlet is available.

you do not have to solder anything to the board if there are posts ic 61,63 on MAIN PCB then just put a jumper across them while you power up. if its just 2 SMD pads just use a needle probe to arc the connection.
Sue, it's not the inverter board. People who don't really know much
about laptops will often diagnose them incorrectly, especially computer
repair shops. The problem you're experiencing is most likely related
to your motherboard. Unfortunately the most expensive part to replace on most laptops.
Your best bet is to probably just have any important files from the laptop extracted by a repair shop and then selling the computer "As-IS" on ebay. Or you could try another local repair shop to take a look at it. I wouldn't pay any money for a diagnostics since it would take most techs about 5-10 minutes to confirm what I just typed.
