So I got this IBM Thinkpad 765d in a pretty good condition overall. Only thing was slightly bothering me is a barely noticeable "moss" smell, like it was stored in damp environment.
Got it without AC adapter, so I connected my spare Lenovo 90w 20V to 2 pins and it's working fine. Even original Li-ion battery still alive and showing 44% on LCD screen.
Thing is, I still can't boot it to OS, with any bootable diskette it showing that screen "Insert floppy, press F1", after second try I get 19990305 error. Floppy drive sounds are normal, seeking and everything, is there a chance it still broken somehow?
Or maybe I should prepare some special disk for it, idk. It's really hard to google any reliable info on this machine.
Also looks like F1 button is not working:
No reaction to F1, and I only hear seeking FDD after I press PgUp/PgDown buttons, not anything else on keyboard. Also can't get to BIOS via standard F1 hold while powering up. Only when I hold PgUp, maybe it's replaced somehow?
After some button pressing and tries I got 301 keyboard error and then able to get into tests. Everything seems to work from there, MB, memory, FDD, screen etc. But no HDD1/HDD2 and I hear no sounds from it too.
On closer inspection I noticed HDD was definitely replaced, it's small 400mb drive instead of original 3Gb, and after reseating connectors several times I finally hear it's spinning and calibrating. Even got to "Starting MS-DOS.." message and then suddenly laptop shuts down. When I try to slide power button, I hear only 2 short beeps and that's all.
Luckily, MB wasn't fried or anything, it still booting fine to BIOS with HDD disconnected and I got only black screen when it's connected (and can hear it spinning/calibrating, but no beeps). After some tries I got "Starting MS-DOS.." and shutting down again, so I guess HDD is not dead, just maybe taking too much power?
Anyway, I'm kinda stuck now, don't have any spare small IDE HDD drives or compatible FDD, so what's next should I try with this machine?
