My customer was attempting to use her latitude d600 to drive a external
projector for a seminar. Somehow she managed to lose video on both the
internal lcd and the external display. Upon booting you have video
until Windows XP
loads (and presumably the point where the video driver loads) then the
screen goes blank while the system continues to boot up. The Fn + F8
keys DO switch activity between the two monitors but there is no
display. Also, in safe mode it will boot just past MUP to AGP440.SYS
and there it hangs. Tried switching modes in BIOS but it's PW locked. The customer says she dissabled something in the monitor settings but can't remember what it was!!

The "melted" IC - this has shorted out, and something has cause this to happen, even if you replaced it, it could short out the new IC unless you identify the cause. The D600 is an old laptop, it would be better to put your money towards a new laptop. You could remove the hard drive and put it into an USB hard drive adapter case and use it as an USB external hard drive..
the d600 has a 8 pins chip,like the c600 where the pasword/faxtory setting is stored.. it's located under the tape where the pcicma socket is..close to edge of the board it sais:UPW1 I think you can use the paperclip methode like the c600 wich means short two pins ( 3& 6) while you power the lap

The flickering may not be caused by a corrupt driver, it could be the impending failure of the fluorescent back light of the display or its high voltage supply.
Trying driver replacement though is the first thing to try.
If the original driver is corrupt, you can try the following;
- Right-click on My Computer - Left-click on Properties - Click on Hardware tab - Click on Device Manager - Locate and open Display Adaptors
- Locate the video listing for your
- Highlight and delete this - Reboot the computer
If Windows does what it should (no guarantee on this!), it will 'find' a 'new device' and install the driver for it.
