Nice to see another Toshiba fan. Yours packs a fair bit of power, especially the tft panel can do 16bit color. But I have to ask, why did you change from CCFL to LED? My T4400C's CCFL does need a little 2 minute "warm up time," but after that it's crisp and bright. Whites are also, surprisingly, …

Completed the recelling of my T4400C battery. Sadly didn't take photos of the job. Used nimh cells to replace the ancient nicd cells, and the charge circuitry does "too good" of a job of charging them. If you fully charge the batteries, then don't drain them enough, it won't charge. Similar to …

The modems were fairly proprietary. While being obviously standard (with typical components). However, there are two ways. You can take the board out and flip it over to look at the main IC, which may shed some light. However, the modem on my T3100SX had even more sparse info. Just dead links for …

~snip Yeah, the T4800 I have suffered the same fate (resume batter leak), and it was clear the previous (not the seller) found out and removed it. There wasn't much damage, would need a serious cleaning. Just powder everywhere. But I do agree, the proper glass covering just makes it look different …

~snip~ Nice, always love seeing another classic Toshiba see the light of day. My T4400 has a nice display, though it takes a little to "warm up." Once it does the colors are nice, sharp and the viewing angle is nice. BA908BFA-B936-4C9A-8249-1E000DB24BCF.jpeg The floppy drive also works, but if I …

Yeah, pretty much a form of delamination, but not the one that makes it non-functional. Pretty much, if you can see the pixels underneath it's fine. It just looks like Toshiba made a poor design choice with plastic cover on this panel, because the older TFT panels used glass over the panel.

Next project arrived today. This is probably going to be the most difficult laptop to restore. The seller wanted 250USD, however I talked them down much less than that.

Repaired a T4400C power supply board. Unit powered up, and I get a nice whopping 20 minutes off the battery. Also swapped the drive with a 340mb microdrive and it worked well. t4400c.jpg For 3 days. Then the LCD started acting funny so I looked in there too. Turns out some SMD electrolytics blew out …

With this machine it is best to dismantle it and air out and dry the metal components asap. There are steel parts that will rust and leave rust dust everywhere and make it ugly. Not to mention the solders will oxidize. And then screws and threads will rust up too, pain to remove later if they're not …

Along the lines of the reaction image detection, I noticed if you have a line break between content and an in-body image (from anywhere), it also classifies as a "reaction" image. In addition, I attempted to upload an image of a motherboard and apparently that's a reaction image too. Not even placed …

Without seeing the machine, it's hard to say. Dry joints are a bit on the lower chance. These units used leaded solder and through-holes, with a few plcc and qfp chips. That said, not impossible, but not very likely. Also, one that I've found examining the panels is that the ribbons that connect to …

Thanks for the suggestion, however: The maintenance manual is incorrect. Notably it labels pins 33 and 34 on machine side connector as ground, when they are actually +5v supply lines. Verified with probing and testing. But I already have figured out the addressing scheme, I just needed pictures of …
