Lost Classmate Power Supply

[Mark McLeod]

It's interesting that the power we'll get this year at the Driver Stations will be 19v too.

According to the manufacturer (CTL) both Classmates are compatible with the 19V supply (and presumably the 20V supply).

Word of caution, and I may be a little paranoid here, but make sure the polarity of the substitute power supply matches that of the missing classmate supply. Off the top of my head I don't recall what the classmates is, but you should be able to see on the casing of the IBM what it is, or worst case take a DMM to it and check.

Just the other day I forgot to check this and put reverse power in to my USB/Serial Port hub and blew the power regulator in to two pieces. Oops. (This is why I own a soldering iron though...)

I was stuck the exact predicament and can say that it worked fine, and no harm was done.
Left the classmate charger in the shop, and found a portable dvd player charger around the house (19v, 2.4A), and was able to work away at home.

Excellent, I'm glad this worked out. I was just concerned about the polarity because it could be very bad for the classmate is connected to reverse power. I'm not sure it has reverse power protection built in.
