SOURCE: Acer travelmate 4650, after bios flashing, no display.thanks.
HI there
Sounds like the bios flash has failed, the only thing you can do now is try to flash again, make sure you have the right bios update for that model machine, suggest you get a USB floppy drive so you are able to re-flash the bios, if it still doesn't work then the machine is rendered useless.
Good luck and thanks for using Fixya!!!

you have got an older model, try this:
follow the instructions:
you will need:
a slim x-screw-driver
a sharp knife with a slim blade and
a cup or else for the screws, don't loose them!
a new c-mos bios battery model: CR-1220 (exchange it while your in there!)
you find c-mos battery and hdd under the keyboard!
- turn off the power, remove accu and charger cable, for static electricity is friendly fire
to your laptop now !
- open your screen to max. fold (angle of 180 degrees)
- look for removable plastic part near to left holder of screen
- carefully remove it
- also remove plastic panel right to it in the section between display holders
metal should be visible now
- carefully! remove keyboard, starting at the left side, continuing topside
as you won't be able to fully remove it, simply turn it over
- unscrew any screws holding the metal plate, remove it
- now you see: left the CPU plus cooler, top right middle the hdd still in an adapter attached
to the mainboard, at it's lower right the C-MOS battery (g
- turn loos these screws
- carefully remove the frame/adaptor holding the hdd
- unscrew again the adaptor
- seperate hd fram adaptor
... and gotcha!
be careful to get a proper notebook hd (samsung or such)
exchange CMOS-battery by chance
reattach new hd to frame, again carefully!
to reassamble: rewind the procedures
put everything back in place
replug, pray and turn on the lappie.
wish you luck.....

most times the battery is located under the ram chips
there is also 2 pins that can be shorted together that will reset the bios password if you cannot see the battery when opening the ram door.
