vista laptops, old.
was the PC parked for over a month (y/n) if yes the RTC batter must be charged first. with power on, run with big battery out, do the long reset in the manual, (power held button on for 10 +seconds)
the manual shows its now 11 years old. (2007 built)
that means the coin cell RTC battery is first thing to die. as they all do. replace that first. ever decade , but the book shows and odd duck RTC battery here.
why did you say video card on laptop.?
the manual, I am reading your manual
this pc has chargeable RTC battery, (odd that) and must be left turned on to charge it (odd duck 2 rules) never buy toshiba's
the laptop has no video card. like a desktop so your post is very very confusing, in that light .
I guess, long the built in LCD died, then you connected an regular desktop monitor to the VGA jack on the rear, and run this?>
be nice to know what you have before your eyes, and all connections stated ,no?
the Fn + F5 key lets you pick internal or external or both screens.
did you know that? its on page 68 in your manual.
laptops 101, white screens of deathh(sic)
1: push power on, no external screens now.(local LCD)
2: fan runs and blows air if not fix this first. clean the vents , and fan paths.
3: ok fan runs.(there is hope) if not remove that old useless 11 year old huge battery now, if shorted now, it overloads the regulators.
4: put in a new RTC battery or charge it some magical way, IDK.
5: now test BIOS, does the bios screens work>?
ill stop here, if BIOS is dead the PCI is dead or the CCFL lamps are dead.
for 11 long years BIOS put text on the screen at boot time.
it tells you the hot key for BIOS entry, if this is dead the PC is dead.
CCFL is the backlamps on old old PCs 2010 or older , after are LED
CCFL go dead on most by now, most are BLACK screen forever now. after 20k hours of usage.
So, I'd retire this old dog, why spend money on any CCFL laptop?
it has street value dead, of $20 or less as parts, as-is.
guy PC 2010 or newer. or with w10-64b loaded and running, big time better that.
the only easy fix here, is cleaning out , so it dont overheat.
and running with no huge big battery run on AC only,saving $20 on new battery,(the battery is worth more that the PC now) so.....
if the fan is dead , you must fix this first.
Sure wish you had told us why you have video cable there
an where it the world a video card fits in side any Laptop.
dont get me wrong , my HP highend Laptop has 4 video cards inside.but most others do not. 99% not,
here are your manuals.
