    My Toughbook cf-c2 has been working perfectly till one day while it was off and was plugged in and charging, I noticed a red light flashing, no other lights on, didn’t read what the light was for. So I tried to turn it on but no response. I unplugged it and took the battery out for 10 minutes and reinstalled and plugged in but now no lights at all and no response to the on switch. Tried the same thing again except while unplugged and battery out I held the power switch on for one minute, reinstalled and plugged in and still seems dead no charging light or anything. I replaced the charger adapter and still no lights and seems dead. I was going to try checking the CMOS battery but can’t find any information on where it is or if it even has one. Any advice would be appreciated!

    Thank you

    Red flashing light is usually the battery.

    Try plugging it in and starting it without the battery in.

    Check whether your charger's output is 16V.

    Yes it is 16v, and I also tried another Panasonic Toughbook 16V charger and no lights still dead.

    I took a look at my parts c2. check if ram is seated. check for damage to the charging port. take out the hard drive and see if it boots. If no results its prob motherboard failure. They are a challenge to change but these models are cheap enough tough to buy a whole unit.

    RAM removed and SSD drive removed , no indication of life after repowering. Where is the CMOS battery because in my experience disconnecting and reconnecting it in other computers works wonders, but I can't find out where it is in the model?

    CMOS battery change requires disassembly of the laptop.
    The C2 is a PITA to tear down.

    Does the red flash even without a battery?
    Try wiggling the plug / cable where the power cord enters the laptop. Bad power port will act erratic when you wiggle the cord / port.
