How can I repair a toasted Palm m505?
Posted on 2004-09-24
I set an m505 in its cradle and plugged in its power supply, but the charging indicator stayed dark. I removed it from the cradle, and it lit up. Put it back in, went dark.
Then I noticed that instead of the 5v power supply that came with it, I had plugged in the power supply to a laptop and have the poor thing 16vdc. Well, I tried plugging in the normal supply and letting it sit a while, but it just got really warm.
Now it makes no sign that it works at all. Soft reset, hard reset and cradle reset all appear to have no effect. Palm wants $125 to fix the thing, which is crazy since I can buy a used one for $50 or so.
Since it's now a paperweight, and I'm pretty darned handy with a soldering iron, is there anything I can do to repair the thing if I should get some spare time? What parts would I need? How do I find out how to test what failed? I would plan on buying broken machines to get parts. What else should I consider?
