Panasonic Toughbook CF-29: Laptop is Powered On but Screen is Black and Wont Turn On

Sun, 05 Apr 2026 15:14:36 -0700

The power light and MP are green lit, and when I plug in the power source the battery green light comes on, but the screen is not responding. Last time the device was used was in April and did not have a problem. It has been plugged into the battery source since and not opened. I have tried taking the battery out and running just off the power source, but same result. I have tried turning off and on a few times, same result. My next thought was to let the battery die and then plug back in and see if that makes a difference? Any advice?

Panasonic Toughbook CF-53: Battery Not Charging and Computer Won't Run on AC Power

Fri, 11 Jul 2025 14:37:46 -0700

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?

Panasonic CF-SZ6: fuse locations, won't turn on after I tried to use a usb hub

Fri, 25 Apr 2025 22:21:45 -0700

where are the fuses protecting this notebook? I found one 15Amp fuse on the main board next to the battery pins, it has continuity between it's 2 leads, so I guess it's OK. I can see no other fuses, and hesitate to take anything else apart. Is there a fuse protecting power inputs to the usb ports on another less accessible board?

I have an AX3 and a AX2. Some of the keys on the keyboard on my AX3 is not working. It happened after I connected an HDMI cable to the laptop then it started getting wonky. After I removed the cable and restarted the laptop multiple times, I still can’t get it to work.

The AX2 also has a problem. I can’t get it to charge despite replacing the removable battery.
