I have actually made a purchase from him about 2 years ago. At that time his prices were a bit lower, but still way to high. I was looking at a sytem he had up for a couple of month already, so that seemed long enough for a very low offer of less than 1/4th the listing price. and to my surprise...

Sorry for the delay, Don't worry, no offence taken. Just wanted to make sure nobody tries to replicate this and risks the chanse of starting a fire when leaving it charging overnight. I think what I would do, (to be clear I am definitely not an expert in any of this) Is to add a diode coming...

Well if you could try and read out the IC that would be great. :) I'll have to check. It has been disassembled in a box for a year or so until I could take the time to do some more repairs. But I'll check if I can beep out the connections.

Still not safe at all IMHO, the voltage drops to the voltage of the battery pack but the T1200 PSU is still trying to charge the battery up to 11.7v, it is still pumping current into the pack. Now depending on what BMS you are using it might cut off the charge at around 4.3v as a safety measure...

I have been doing some research on the battery replacement. Mainly because it is a fun project and because it would be really cool to have one of the T1200 unique features up and running, that is it was the first portable computer to have a "sleep" function. It could be unplugged from the wall...

Don't rally have one to to open now. but I will try and see if I can revive one of those 20MB drives now that I know there is more on the inside. I've done many repairs on 20 and 40MB Connor IDE drives so I have some experience with what not to do. like, don't blow them out with compressed air...

you should take a ook at this thread, we were just discussing these hard drives. it might be worth trying to repair it. Absolutely no guarantee that will work with this 20mb drive but it's certainly worth a try if it's dead anyway...

Very interesting I haven't disassembled any of these to that point. I wonder if this is the same on both the 10mb and 20mb models My success rate for recapping (outside) and unsticking/lubricating spindle are: 10MB: 9/10 working reliably, last one doesn't spin up all the time, still has a...

strange, I haven't seen that yet. please post back when you have tested with another drive :) That's totally normal, the T1200 wasn't originally developed for a backlight, it only was available without one at the start, and then later they offered the backlight as an option or upgrade. at the...

that's strange first time i've seen one that doesn't spin up at all. have you tried "starting" it when the T1200 tries accessing it, when the drive indicator led is lid. maybe a stupid questing but have you checked that the HDD switch on the PSU is on? If the drive access led comes on and the...

Of course. :) The spindle is on the bottom of the drive. Use needle pliers to turn the inner nut clockwise (be careful not to damage the grounding tab). Don't have to turn it a lot, just break it free and then power it up. Best to keep it running for a while to make sure it doesn't get stuck...

No problem, just let me know when you retire it, or want to trade for something else :) The MCU is a PLCC 8742AH. so a bit annoying to desolder. It has the ability to enable a security bit, no idea if they locked it.

Awesome, thanks for the info. I would love to try making one and do some testing. I wonder if the BMS is enough protection with a weird charging setup like this. Will have to do some more research. :)

I'm afraid that won't work. These expansion cards are more like ISA cards than direct HDD replacements. They connect to the Toshiba expansion slot which exposes an ISA compatible bus. They don't work with the internal HDD controller but contain the XTide bios.

Awesome, looks great. Happy to see another T1200 restored and running with it's original PSU, often these get so destroyed by capacitors leaking that they require mayor rework. The whine from the backlight inverter is normal on these, nothing to be worried about. I think they always were like...

It has been a while since I had mine apart, but if I remember correctly I think you have to unscrew the display hinges to take the top off.

Ohh that display looks like it had a rough time. Thanks for the pictures, mine is missing the label on the bottom, I actually started looking for one after seeing it on the computer chronicles; worth watching to see one in operation. From what I read it looks like the company had a lot of...

Very cool. I have one of these but unfortunately many of the components are shorted as the previous owner hooked up a 12v to the 5v input. I've been trying to restore mine, it is complete but obviously needs a lot of work. Would you mind sharing a couple of pictures of yours? Also what serial...

No problem, if you want I can make some better pics from mine. If you end up making labels or a template. Please share them here. :) tnx

If you want I can take some pictures from my Gridcase roms here are some pictures I found digging trough my files, some are from the web, some are from my own collection.
