Every once in a while, someone comes to the TRS-80 Model 100 mailing
list asking how to recover a laptop they bought off ebay that is
unresponsive to the power button.

Although the Model T laptops use standard AA batteries, understand that there is an internal battery soldered to the motherboard.

Often with units that have sat unused for awhile these problems occur:

* the nicad is drained
* the RAM is in some random state
* the contrast knob is in some random state

You need to resolve all three, but you need to do it in the right
order. Almost always you can recover a Model T without resorting to
more serious troubleshooting.

# Leave the laptop plugged in to the wallcube overnight with Memory Power switch on, and the power off. I don't think it matters whether you have AA's in at this point.
# Let the unit sit with the Memory Power button off and no plug or other cables connected or batteries in the battery compartment for about 15 minutes in order to clear the RAM.
# With the power-button ON, hold down Ctrl-shift-break simultaneously, and hit reset button to clear the RAM

Now fiddle with the contrast knob. Hopefully you will see the normal Model 100 main menu.

== Tandy Disk Drive Emulators ==

TPDD emulators, in concert with a compatible disk clients like
TS-DOS, TEENY, POWR-DOS, FLOPPY.CO, the Booster Pak, or the
WP-2 built-in Diskette client are the most "advanced" way to
accurately and quickly transfer all file types including binary
files to and from your Model T laptop. There are different
options for the server side on modern operating systems and
devices:

[[LaddieCon]] is a TPDD emulator for Windows written in C#.Net.
