I just bought and installed a new HP Pavillion computer. I had a HP Deskjet D1341 connected to my old computer that was working fine, After installing the new Pavillion and conecting the printer to the USB...

disconnect all the cabled from the printer and leaving behind only the power cable.
Then try turning on the Printer. If it still doesn't turn ON then it means that its a hardware fault. Please consult HP for it. But if in case it does turn ON (the chances of which is very less) then it could be a software issue with the computer. Let me know what happened.

Hp pavillion screen on laptop is a white out

Have you dismantled this recently? If so, check that the video cable from the screen to the motherboard is firmly in its socket.

If you have not, then try to connect it to an external monitor and see if the problem goes away, that will eliminate the graphics chip if it does. You then need to look at the screen itself, checking all connections are tight. Normally with a white screen, the backlight is working and I would think the inverter is too (although not definate), and it would apppear to be the connection between the mobo and screen.

If it still persists, there is a much deeper issue with the motherboard

This is a common problem for many HP DV series laptops. The problem is caused by the faulty Nvidia chip. You will need to replace the motherboard. The other option is to reflow the motherboard youself. You can check out the DIY guide on . You can not connect the monitor via the connector port underneath the keyboard.

  • Check your power cord & adapter.
    If its working then check the battery, reseat the battery & check.
    If available then check with another battery
    If no, then remove the battery & switch on the PC in AC mode.
    Check if battery charging indication or AC power on indication is glowing. if not then need to change ur motherboard.
    If indication is OK, but could not power ON then check ur RAM for any loose connection or dust. clean & reinstall.
    If still no display, connect an external monitor, check if display is comming.
    If Display is coming then your LCD need to replace.

SATA cables are not brand specific and can be purchased at any computer store or on eBay where you save a lot of money and have endless selection. Measure the length you would need and buy the proper length cables. You want to check the length of the power cables too.

HP Pavillion dv6110us Speakers not working

The sound power comes through a ribbon cable to the power button,along with the power supply switch wiring. This "power ribbon cable"( part # 431437-001) has frayed where it connects to the motherboard.
The new cable will cost you about $5 with free shipping on ebay and takes about 10 minutes to replace.
You can find step by step instruction on the repair by searching "dv6000 power ribbon removal".

Monitor on HP Pavillion a656x---blew up the power supply--had an extra and installed it--when machine was turned back on--monitor displays "VIDEO CABLE CONNECTED?---what am I going to do----help!!!---

First thing I would do is try the monitor on another system to see if it's in the monitor or computer. Next would be to fire it up and see if you hear a beep from the motherboard. Most consumer pc's will come with a small speaker that sounds on startup. If you don't hear this beep it could be indicitave of a fried motherboard.

But it sounds to me like your video card or onboard video was messed up when the power supply conked out. If it's onboard video you may be able to switch to a video card. If it's a video card you may need to replace it.

Also check to make sure there are no loose wires, that your video card is seated firmly, and that your connectors are all snug. If none of this works then you're most likely looking at a motherboard replacement.
