Question about Panasonic Toughbook 28 Notebook
> battery light turns RED
For Panasonic computers, that indicates that the battery is almost completely discharged (it's YELLOW while charging, and GREEN while fully-charged).
So, my guess is that your AC adapter has failed,
and that your battery needs recharging.
Or, the socket where the AC adapter connects into your computer is damaged, such that no power from the AC adapter is reaching the computer.
Take a "MultiMeter" and check the voltage & amperage output-level from your AC charger. If "zero", go onto eBay and search on the part-number, to find a compatible replacement part.
