Hi
I have an R31. It came with a dead battery. I bought a genuine IBM one from ebay and it works, but if you pull the lead out while it is charging it locks the laptop up.
Two of the lights under the screen - caps lock and the screen one - flash.
It does it in Ubuntu, but works fine in XP.
Any ideas?
I have the same problem with one of my laptops.
If I remove the audio-out lead while it is switched on it crashes with two flashing lights. (Num lock and cap lock I think).
I suspect it is caused by a (static?) discharge as I have been able to measure a potential of about 150 volts between the two devices (laptop & TV set) although there is no current available to do any (much) damage.
I just fall back on the old hardware adage of "don't plug or unplug under power".
