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?

you maybe able to take the floppy out of the laptop and take it apart and clean it. It sounds like a bad floppy drive. But I would get the floppy drive working 1st, and id remove the harddisk totally. Get to the point that it will boot from a floppy. After that you can trouble shoot the HDD drive, or possibly ram failure. Baby steps.

Thanks, so I opened floppy drive, and looking pretty good and clean inside. Did a simple head cleaning and sightly oiled screw shaft, still not booting. Guess I should try to clean/reset a motherboard next

Ok, so while I have no options to boot, I ordered CF to laptop IDE 2.5 adapter, and PCMCIA to CF card too. Hope these will work on such an old machine, they are very cheap anyway.

Disassemble the whole laptop and check if the standby battery has leaked onto the motherboard.
Check for dried out caps in the power area of the motherboard. Sometimes leaving the system on the charger for a day does do wonders too.

I suspect your motherboard has some issues which makes this happen, find the problem, fix it and enjoy your system!
