It may be the cable that attaches behind the screen is loose. If you type in your model# and "lcd replacement" in Google you will often find a tutorial on how to take it apart. Patience though our you will break something!

White Screen Compaq Presario CQ60

Regarding ; White screen , I flipped my notebook over and removed the power source(s) , power cord and battery. I then removed the three screws in the battery cavity and the two outside corner screws to gain access to the connection for the LCD and found a loose connection. It seems that the wire that connects to the screen was being moved every time I opened and closed my computer. So very glad to find that bulb and inverter board was not bad. Prior to this , I did try external monitor and found that all was okay as far as operation of start-up.

Compaq Presario f700 NOTEBOOK.
first off im amazed it can even blink bark or glow at all
laptop are scaled in DOG YEARs.
my first guess is the not tried yet, exernal VGA jack works
so only your screen is bad.
as all are now with CCFL lamps dead or its power pack.
called "inverter"
the lamps go dim, yellow ,flicker then die, all do if CCFL
best is upgrade top LED laptop and w7 and newer OS.
the BIOS pages must work or the screen is bad
seems power is ok, to me. and you.
it came with VISTA.
year 2007?
im reading your service manual now.
and see this?

that is CCFL lamp not LED>
this is bad or the inverter card that drives is is bad if BIOS FAILs
to show in the screen, My best guess, no tests by me,
testing is the only sure way to fix problems not guessing.
why not get tech to fix it?

When I turn on my presario f700 I get a black screen, been told it is the bios chip??

If the laptop appear to boot up (ie the hard disk LED flashes) but you cannot see an image on the screen, then you could have a backlight problem.
To determine the actual fault, please follow my instructions which are on this link :-

Compaq F700 Battery live very less

Its normal, generally it comes with 80-90 min. You can use HP Power management to optimize the use of battery. Making screen less bright will increase the power backup.
