Panasonic Toughbook C51 - no power

cbstech1 · 05-26-2009, 08:01 AM

I have a C-51 and it will not power up. The only thing I did was take the battery out and put back in. I have taken it out and made sure it is going in correct and the connections are matching. Also it was working fine before I took the battery out.
Is there some sort of reset when you take battery out?

Test output voltage of AC adapter or test it in another (similar laptop).
Test battery in another (similar laptop)

.

Also Try to:

Startup on battery only (make sure battery is charged/working)
Startup on AC only

If symptoms persist or if this has been done...

Try the steps below:

Power OFF the computer
Remove the battery
Unplug AC
Press and hold Power ON button for 30 secs. at least
Put back the battery
Plug back AC
Power ON as normal

If the same thing happens...

Take it apart/Disassemble the laptop
Remove the rest, except RAM, mobo, LCD and power ON switch
Power ON using adapter
