Having problems with your HP Compaq Presario F730US Notebook ?

Compaq Presario F700 turns off just a second after the start button is pressed... any ideas?


Answers :

Try holding the esc button when turning on the notebook the power button light should stay on if the hp logo doesnt come on then turn it off and unplug the notebook and unplug then remove the battery plug the notebook and hold down the esc button and start it let the notebook on for about 1/2hour then turn it off and unplug it put the battery back on and plug it press the power button and it should show the hp logo press f10 to go in to bios then change time and date to current and allso change the boot order
Not a solution (yet), but ample experience with a broad range of laptops suggest a normal order of checks on a non-functioning F700 on the bench in front of me (pressing the power button gives about 1 second of indication on the power LED). The LED ring around the power jack show OK, and checking w/ DVM verifies reasonable PS voltage.
1-Remove battery. No change. Battery is totally dead (checked w/ DVM), so I charged it external to the laptop. I'm a rocket surgeon brain scientist, so I know how to do stuff...
2-Remove HDD. No change.
3-Check RAM. No change.
4- Replace battery after getting close to full charge. No change.
5- Every step I have also attempted a hardware reset holding down ESC, then attempting to power-cycle w/ just the PS, without the battery installed, without success.
6- The problem requires a teardown. It is either the power switch (very unlikely), the power jack (unlikely, with a functioning.LED and the switch LED flashing), or on the motherboard. The only reasonably-practical MB repair being the solder reflow on the GPU, and the unlikelihood of that actually solving the problem relegates this to the scrap pile or the wild-guess project category.
