I recently purchased a Panasonic CF-41 and it came with its original AC adapter, I tried to test it and it turns on but nothing shows up on screen, I try to plug it into a external monitor but still nothing shows up , I opened it up and it turns out the battery was corroded so I cleaned it out and I removed it, I can hear noises from the computer but no lights except for power come on except for when I open the CD tray idk if this is a motherboard issue or what but I am hoping I can restore this computer
