To resolve this issue you may need to open the chassis (the computer cabinet). You can call HP specialized support for help but they charge you for the support. You can call them at 866-211-5207.

OR - Follow the given steps.

Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure: CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.

  1. Disconnect everything from the computer, including the power cord.
  2. With the power cord disconnected , press the power button on the front of the computer for five seconds. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps. NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply
  3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America. Performing this step ensures that the voltage switch is engaged and set correctly for your country/region. Figure 4: Voltage selector switchMy hp pavilion a336n will not turn on. When I plug - c00517964.jpg Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
  4. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
  5. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it. NOTE: If you find the device that was causing the problem was a surge protector, resetting a breaker or fuse on the surge protector may fix the issue.
  6. Remove all attached devices except for keyboard, mouse, and monitor.
  7. Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating.
  8. Check the power switch:
    1. With the power cord disconnected, press the power button on the front of the PC. The button should release easily and not stick in the socket.
      • If the button sticks, it should be replaced or serviced.
      • If the power button does not stick and appears to be functioning, continue using these steps.
    2. With the power cord disconnected, remove the case or side panel.
    3. Follow the wires from the power button on the front of the computer to their connection on the motherboard.
    4. Look at the power switch cables connected to the motherboard. If the cable has become disconnected, connect the power switch cable connector to the connector on the motherboard. Figure 5: Power switch connector on Motherboardc00517968.jpg
    5. Replace the side panel, plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
  9. Find the defective part:
    1. With the power cord disconnected, remove the case or side panel.
    2. Disconnect all power cable connectors from their connectors on the motherboard and from the back of internal devices (the back of drives). Make sure to label or remember where each cable connects for future reference. Figure My hp pavilion a336n will not turn on. When I plug - c00540428.jpg common power connectionsc00540428.jpg
    3. Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:
      • If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.
      • If the LED is still flashing (it should not flash with all connectors removed), plug the power cable into a different power outlet that is known to be good. If the LED still flashes, the power supply should be replaced.
      • If the LED light is now off, plug the power cable into a different power outlet that is known to be good. If the LED stays off, the power supply should be replaced.
      NOTE: If an electrical storm or power surge has recently occurred, then it is more likely that the power supply, the modem, or motherboard is damaged and requires replacement.

Install power supply


No Power on an HP Pavilion PC Desktop b> Desktop computers are simultaneously more complex and easier than laptops when it comes to troubleshooting. There are more physical components on a desktop, so locating a specific troublesome part can be tricky, but working inside of a desktop computer is straightforward compared to opening and fiddling with a laptop. Power problems are always hardware problems. There are a few simple, preliminary steps to troubleshooting, but power problems often require opening your computer and having a look inside.

The Basics
Unplug everything from your PC except for the power cord. Try turning on the system and look for lights on the front, then on the back. When the power supply is on (receiving power), the small light beneath the plug turns green. If this light doesn't come on, the problem is either connected to the cord or the power supply. Try swapping power cords with the monitor cord to isolate the cord as the source of the problem. Look closely at the voltage selector and make sure it's set appropriately for your country -- 110 in North America and 220 for most other regions. b> The Socket b> Unplug the power cord and switch the voltage selector to the opposite setting. Wait five seconds, then flip it back. This ensures that the switch is engaged. Plug in the power cord again and try turning on the PC. Check the outlet to make sure it's working, and plug your computer direction into the wall socket (remove it from any surge protectors or power bars). Check the power button. If it sticks when you push it, it may not be making contact to engage the system power and will need to be replaced. If the button is going in and out freely, you've done about everything you can do from the outside of the computer. It's time to go inside. b> Open it Up b> Unplug the power cord and hold down the power button for five seconds. This clears all electrical charges from the circuitry and makes it safe to open the computer. Remove the side panel from your system. This process varies a bit from model to model -- some have one or two captive screws on the back of the system, some have an easy release button. Check your manual. b> Power Button b> Locate the power button from the inside and trace the cables to where they plug into the motherboard. Lift up on the connector and then push it firmly back down. Plug the PC back in to its power source and try to power it on. Unplug the computer immediately if the system doesn't power up, and continue troubleshooting. b> Hardware Components b> Disconnect each of the devices in your computer one at a time to locate a faulty piece of hardware. Power cables run from the power supply connect to your optical drive, hard drive, floppy drive (if one exists) and into several places on the system board. This step takes some trial and error detective work and a few minutes: unplug one device, reconnect the power, and try turning on the system. Then disconnect the AC power, plug the device back in and try the next one. If the system powers up at any stage, the device you are unhooking is shorting out the power and needs to be replaced.

The laptop wont turn on. i have unpluged it, taken out the battery then replace it after 60 sec. tried to turn it on and it didnt work. i plugged it back in waited about 5 min and it still wont turn on....


This sounds like a motherboard problem, unplug computer and remove main battery and leave it out. Now plug in power adapter, press power, if no! remove the hard drive, power up to see if you get a screen prompt, If no! remove one stick of ram, if no! remove the second stick and make sure you put back the first one, if yes! the stick in your hand is bad, if no! there is a motherboard issue. If all this fails put everything back except the battery and power supply, next hold down the power button for 40 seconds, after that time install battery and power adapter and press power "this is a last ditch effort"

Hello

Do a hard reset on the laptop by removing all cords and connections from the computer, including the power cord. Turn the computer over and slide the tab next to the battery, then lift the battery out of its compartment.

Eject any SD cards currently inserted in the SD card slot by pressing on them, then remove them from the slot completely. Hold the computer's "Power" button down for at least 15 seconds, then plug the power cord into the computer and turn it on.

Watch to see if the LED lights near the "Caps Lock" and "Num Lock" illuminate. If the lights do not turn on and the computer's screen remains blank, inspect the power cord and AC adapter for damage and replace them if necessary.

Leave the power cord plugged into the computer and snap the battery back into its slot. Allow the computer to sit for at least 30 minutes, then unplug the power cord and press the "Power" button again to see if the computer will turn on.

Plug the power cord back into the computer and try to turn it on again. If the computer turns on, replace the battery with a new one. If the computer still does not turn on, take the computer to a repair shop.

Start taking your laptop apart piece by piece and test it after each removed component:
1. Remove the hard drive and test the laptop.
2. Remove the DVD drive and test the laptop.
3. Remove the wireless card and test the laptop.
4. Unplug the display panel from the motherboard/video card and test the laptop.
etc....
Continue taking it apart until you have only three major components connected: motherboard (with video card), processor, and memory. If you still experience the same problem, most likely it's bad motherboard.
By the way, before you start, try reconnecting the memory module. If you have two modules installed, try removing them one by one and test the laptop with each one separately

HP Pavillion dv9700 won't power up


Try removing the battery and using only power cord to turn the laptop on. If that fails, try turning it on without power cord, just on battery.

If none of those work, then most probable cause of your problem is motherboard. Hopefuly you are either under manufacturer warranty or you have extended warranty with your vendor where you've purchased the laptop.

If your laptop turns on on power cord, but without battery, then battery is the problem. Also, if laptop turns on when it's only on battery but it doesn't when you plug ac cord in it, then the adapter is the problem.
