I am upgrading a HP Pavilion ZE4900 notebook for a friend - I replaced the current 256MB stick of RAM with (2) 512MB sticks of ram and now there is no video.

I removed the new memory and put the old memory back in but there is still no video and I also connected an exteranl monitor witht the same results.

There was no beep to indicate that it did not like the new memory modules. I removed the battery and AC power -- held down the power button for about 45 seconds to reset the system, but there is still no video when I re-power the unit.

I noticed a "reset" button on the bottom of the unit and I pressed and held that down for about 45 seconds using a paperclip but I get the same results.

Has anyone had this same issue with a similar HP laptop and if so, what was the solution to get the video back.

Thanks in advance for any assistance in this matter.

No flashing cursor on either the LCD or external monitor - the LED's at the top of the keyboard all come on and remain lit.

If the video chip has indeed gone south - is there a fairly simple chip replacement or would we have to replace the entire motherboard?

Also, if the unit is turned on and I press the reset button the unit then powers off -- is that what it should be doing? If so, do I then need to remove the AC power and battery before attempting to power up again?

Thanks for your assistance.
