Since last week, I went to work on a Bondwell B310 laptop that I paid $30 for at a thrift store. The main issue was the display was acting weird, and I figured those LongLife capacitors took a piss.
So, I decided to recap the whole system since the other caps had probably thousands of hours, and they were 30+ years old. I also made a boot diskette with GSETUP so I can determine the correct HDD parameters so I can boot from it, I replaced the 3.6V clock battery with a 3V coin cell battery, and it's working without issues. Well, somewhat. The display is still acting a bit weird (the contrast goes down on its own), which makes me think the slider is failing and not capacitors since I replaced all of them.
It has a Conner CP-3044 43MiB/40MB HDD, 1.44MB Teac FDD, Harris 286-12 0WS, 1MB RAM, CGA video, mono 640x200 display (no backlight), and for $30, it's a keeper. I just need to install a better version of DOS, like FreeDOS and see if I can get my one device to work on it.
