Hello everyone! I can report that the standard 1.44 3.5" floppy drive works well with the controller of the T1200 (and T1100Plus as well). To test the setup I used Dupont connectors (ordered a 26-pin ribbon cable and connectors for the permanent solution). I used this pinout (source here)...

I'm not trying to prove something, I need a better solution to my problem with this laptop, and as am I judge by the quality of your 3inOneEnder you're the right guy to ask. Edited: If my messages sound wrong please consider there's a possibility that because of my bad english

Thank you very much for your time. Please can you elaborate on this? Is it possible to make this setup safer?

Hello, everyone. Hi @Conventional Memories so what we have RN: 1. The discharge is OK (I can report that the laptop beeps and the "low battery" LED is turning on when the battery is low) 2. Charging current is kind of okayish (though slow) 3. Now the charging voltage - it's higher than it...

Hi! Thank you for such a detailed answer! I will read it tomorrow thoroughly and reply. For now - yes, I understand how dangerous these elements could be. And to make things worse look what I did :) 14500 with an AA cradle + BMS for the hard RAM

Thanks for the video - that's exactly the my case. Now I'm almost sure that problem is in the hdd itself.

Oh, that was the way how they did it at the factory back then! Thanks for the explanation! I thought it was some kind of jump wire that was made during the life of the machine. ICE oooooh that's what it stands for in cirtuit emulator! Anyway, that's not the power issue - I checked all 3 voltages...

Yes, I tried to start it manually, and no reaction - looks like it even not trying to start at all. HDD LED only blinks shortly. The reading head is trying to move but the spindle is silent. I double-checked all voltages from the PSU, and at the HDD controller board everything is fine - there...

I replaced all leaked capacitors (don't have an SMD capacitor in stock, temp solution) and oiled the spinner bearing, moved it clockwise but no luck - the drive doesn't want to start the spindle. Maybe some electronic issue. I bought another T1200, will see if that drive will be OK. Anyway -...

Got it! Thank you for the detailed explanation! Appreciate. I'll let you know how it turns out.

Can you please elaborate this method? Not sure how to turn the spindle manually

You're very welcome! Please share the results with us if you'll do so!

It turned out well - now I can take T1200 to the pub, show it to friends, and play some games. It works from the battery for at least two-three hours, so I don't know if a "low battery" LED works as it should. But what I do know is that when the batteries are charged that indicator near the DC...

There are questions left - Is the high-pitch noise from the display inverter inevitable? It's not that loud but noticeable. Or it's my exemplar problem? BTW You can activate composite Video Out by pressing Fn+PgDwn and it works very well!

T1200's main battery is 7.2V so I decided to use four 18650 elements in 2s2p (two serial + two parallel) with 2s BMS board and it works well. I replaced a built-in 2.4 rechargeable battery with a CR2032 with a plastic cradle connected via a diode to prevent charging voltage from the motherboard...
