My intention to post weekly updates about the T1000LE PSU debugging hasn’t really worked out as “real life” got in the way a bit. Nevertheless, here is another, hopefully last update about the PSU as I’ve managed to repair all three machines. As I mentioned in my last post about these machine I started debugging, …
Today’s post is about debugging the T1000LE machines, specifically their power supplies.As I had to wait for some stuff to arrive for my mouldy Commodore 64 I had some time to dig deeper into the mystery that is the T1000LE’s PSU circuitry.And I went in, deep. I also posted to the Vintage Computer Federation forums …
IDE drives, also known as PATA drives are a dying breed.Being superseded by SATA and M.2 this long-standing standard for hard drive interfaces has been discontinued for years now. This poses a problem for vintage computer enthusiasts like myself as these drives are no longer being manufactured and the existing ones are starting to show …
After my post yesterday I did some further testing on both machines.My suspicions were confirmed by desoldering and testing Q502, it was shorted out on both machines. Stranger things As this 2SJ182 is a Power MOSFET capable of handling -600V drain-to-source, 15V gate-to-source and around 1 amp of peak current (as shown in the datasheet) something …
As anyone familiar with these older battery-powered Toshiba laptops knows, these things are finicky at best when it comes to their power supplies. Especially electrolytic capacitors and, apparently, MOSFETS are a problem. The good A year-and-a-half ago I posted about my T1000LE and that it was back to life.That, as it turns out, was a …
I thought it was time I posted another T1000LE update because (quite obviously) everything went not as planned.I really wanted to get the video done by now but editing is a lot of work and since the December festivities start early here in The Netherlands I didn’t have all the spare time I wanted.My aim …
The new capacitors for the Toshiba T1000LE I talked about in my last post were delivered this weekend. I really was hoping to make some good progress, but of course I ran in to some troubles. The first problem being that unfortunately two of the capacitors are in backorder. They will take two(!) weeks to …
