Lappy is suddenly shutting off without warning- could be bad voltage on power supply- broken wire in it (though I don't think so- seems fine. and not moving it), bad OS (shouldn't happen w Linux- you ever hear of this problem in Ubuntu), over-heating in processor (have temp meters and should have warned), or motherboard/power regulatory system broken. But then it didn't turn on at all and thought it was dead. This is after $200 of parts- everything is new. I have 2nd similar one for netbook (also ACER), but it's 2 amps (40W) too small. Could that hurt it?
Running Ubuntu 10.4.1 on ACER 5003Wmli 2gb ram, 1800Mh Turion 64b processor, 333 Mh Fsb 400Mh Ram
In forcing the MAC address to change was getting this warning when it first connected to LAN internet- can this damage anything, or leave it open to attack?
NETWORK SERVICE DISCOVERY DISABLED: Your current network has a local domain, which is not recommended and incompatible with the Avahi network service discovery. The service has been disabled.
First, I guess what stupid software protocols can get turned on to force shut-off like that, and what can I run to test power system (if voltage OK or maybe some error report). I'm afraid to do anything till I test the lappy w another power supply- shut off 3 times (after 10 minutes, 10 seconds, 5 minutes.. I think)
