In my last post about the Toshiba T1600 I took a first look at the machine and explained my first troubleshooting steps towards fixing the power supply (PSU) board.This post will go a bit further in-depth on the PSU, in on of the next posts I’ll explain a bit on how it works. This series …
And more PSU debugging Back in October I acquired a Toshiba T1600 for very little money.It didn’t look all that great from the advertisers pictures and was, as most of these late 80’s/early 90’s Toshiba laptops, sold as not working but I thought I’d take my chances with it.I really like the funky nature of …
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 …
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 …
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 …
This is just a quick post as I haven’t made one in quite a while, and for a change it’s not about OBD2 or ELM327 stuff, but rather about some of my Vintage Toshiba laptops. I recently acquired a vintage Toshiba T1000LE laptop which has, as the seller told me, “possibly power supply issues”. Basically, …
