Question about HP Pavilion dv7-1129wm Notebook

1 Answer

HP DV7 laptop turns off after about 45 seconds.

I just replaced a motherboard in an HP DV7 laptop. the unit comes on for about 30-45 seconds (plugged in or on battery) during which time I am able to go into BIOS and look at some settings OR let it try to start windows. After at most 45 seconds the unit powers off. I am not sure whether this is a heating problem although I did put thermal grease on the heatsink and can hear the fan turning. Any ideas folks? I am 89% sure it is not a battery or charger problem.

It is graphic card problem, its very common in dv7, the display chipset fail to render properly and system turn off, if system under warranty ask them to replace bec its very common and if warranty is near to end then definately go for extended warranty.

After pressing the power button, my HP dv7-1129 laptop only stays on for about 2 seconds and then shuts off. I completely replaced the DC cable and now it receives power, but it does not boot up. What is...


try taking the battery out, unplug the DC cable and hold down the power button for 30 seconds this will get rid of the static on the motherboard which could cause the problem.
After you have done this put the battery back in, then the DC cable then try to turn it on.

If not it could be your battery because you are getting an indication that you are receiving power, try taking the battery out and just plugging in the power cable.

Hope this solves the problem.

Was using my Hp Pavilion dv7 laptop, suddenly turned off while the charger was plugged in. Turned back on then shut off again. Now my laptop wont even turn on, and there are no lights that even come on,...

1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.
