i have a tulip nb486sx laptop...
it was working when i used it two months before.
now when i boot it...it boots fine and shuts the display off after a few secods...it still responds to commands and hence just the display is off.
the display comes back fine if i reboot using keyboard or power switch. but same story repeats.
if i close the lid, it gives three beeps and display comes back again just for 2-3 seconds.
i am using external power...if i use it without the external power, it still behaves same...this means battery seems ok...or is it not???
if i remove the battery and just connect ac power,, it still behaves the same...
the laptop has external monitor connection...and that gives proper display when the lcd panel is not disaplying anything..
what to do???
