Chosen Solution
just bought a refurbished Panasonic Toughbook CF-53 a while ago, and while it’s working well enough so far, as a couple hours ago the battery has mysteriously stopped charging. When I plug the adapter in, the battery light turns yellow, then starts flashing red about thirty seconds later. I have no clue why it does this, the most intuitive answer I can think of is that the battery died, but I have no idea why it would die so suddenly. It was on something like 14% charge and charging while plugged in last I checked, but now ot just won’t work, and since the computer can’t seem to run on AC power alone that means it’s bricked until I can figure out how to fix it. The only thing of note that I can think of that happened before the battery failed is that I was playing AdventureQuest that seemed to cause the computer’s fan to start running really hard. The game isn’t particularly graphically intensive though so I can’t see why that would do this to the battery Any advice?
@zennistrad “Refurbished” by who??? I wonder how thorough? Amber light indicates charging and flashing red is either the battery itself or the charging circuit is defective. During “With the battery inside it will boot briefly but then immediately shut down” does the fan come on at all? Change speed? If the fan speeds up you could try checking the heat paste on the CPU - too much, too little or too old paste could cause heat problems.
