Hello. I have a problem with an COMPAQ R3000h 242705-002 :( . When it is plugged in
to the electricity it turns itself off after a few seconds after manual
switching on and than turns itself on again for a couple of seconds. When
it works on battery it works just fine. What may be the cause of such a
malfunction? Thank you very much in advance for any help you can give me. :(
