[ltp] ThinkPad 770 suspend/shutdown at random

[linux-thinkpad@www.bm-soft.com]

As has been relayed, you do need a charged (nominally full) battery to
perform a SETUP upgrade.

Additionally I would confirm you have the correct charger/adapter for this
laptop (early 770, correct?). Using the incorrect power adapter is not
recommended. I also wouldn't recommend a non-IBM unit. I have yet to find
a universal unit that was any good. A sure way to ruin your power system.
My opinion of course.

I suspect you may have a power system problem. Switch(main), power unit or
DC-DC converter. I would lean toward a DC-DC converter. One check is to
see if it will charge a known working battery, which you lack. 

If you can locate a inexpensive battery (find a loaner?) then you could at
least try to update the SETUP util. There isn't a power test in SETUP
which would be nice.

You haven't setup any APM have you? I lean toward the power system problem
and that requires service center work or aces to parts and a schematic. 

ThankYouKindly!
