Having problems with your HP Compaq Presario F730US Notebook ?

Presario F700 ... Wont boot up, Turns on & then off ... That's it ... Anybody got any ideas on why it does it ...

Answers :

Had the same problem. In my situation it was related to the Graphics processor. Remove the memory access cover and apply firm pressure on the corner of the simm socket and see if it starts / boots. Also try downward pressure from the top side left of the touchpad. If it works then you need to put a shim on top of the GPU chip (between the plastic base and the GPU). I used an old rubber foot from an old case. Reassembled... so far so good. Note: if you look at the GPU you'll see that it's glued in addition to being soldered. A manufacturing "fix"... obviously a known problem.
My daughters F700 was working OK and the next time she went to wake it up it wouldn't boot!
\015\012The HD light would flash once and I'd hear it grunt twice. The fan would start and almost immediately stop. The screen was absolutely BLACK.
\015\012I tried all of the remove the battery and power adapter hold down the power button tricks to no avail. Including taking out the RAM and also disco the BIOS battery.
\015\012Nothing worked. What saved me was a comment by one responder, that he just left it on. The trick is to get it to stay on. I did by putting a restore disk in and it seemd to stay powered up.
\015\012I went away for about 20 minutes or so and was sitting at my desktop and heard things happening with the laptop.
\015\012When I checked I found it still with a black screen, but the fan was now running constantly. I took out the startup disk and tried doing a keyboard reboot. NO DICE!
\015\012I then held the power switch until the laptop shut down. I waited a respectable 3 to 4 seconds and powered it up. Lo and behold there was the BIOS setup screen. I hit F1 to proceed and was sent to the SAFE MODE select screen. I chose Normal Startup and the laptop booted up and worked.
\015\012I chose to go into the control panel and disable sleep mode for both battery and powered modes. Naturally I will never select sleep or hibernate when I shut down either.
\015\012The trouble with this situation is for all intents and purposes, you would consider trashing the computer.
\015\012Hope this helps. JOHNNYBOY
