Installed replacement battery. Unit turns on for a few seconds to a few minutes and then shuts down. Unit continues to turn itself on and off (with no action by me) for a few seconds to a few minutes until battery runs out.

Hp pavillion lighitng bolt led on front keeps flashing and will not power on


I see that you said that you "powering on the AC adapter only".
Does that mean you tried booting with the battery removed?
If not, completely remove the battery and try to boot.
If that fails too, it will be a switch or board issue

My hp 2100 presario laptop in not booting


Startup problems
If the notebook doesn’t respond when you turn it on
• Connect the AC adapter.
• Reset the notebook by inserting the tip of a paper clip into the reset button on the
bottom of the notebook. Then press the power button to turn it on.
• If the notebook still doesn’t respond, remove the battery and AC adapter, remove
any PC cards, and undock the notebook if docked. Then plug in the AC adapter
again, and reset the notebook using the reset button.
If the notebook won’t boot from battery power
• Make sure the battery is properly inserted and fully charged. Check the battery
charge by removing it and pressing the pad on the side of the battery. The lights
show the charge level.
• If available, try another battery.
If the notebook won’t boot from the floppy disk drive
• Make sure the floppy disk drive is selected as the boot device.
• If you’re using a USB floppy drive, use the BIOS Setup utility to make sure
Legacy USB Support is enabled. If your notebook also has a built-in floppy
drive, use the BIOS Setup utility Boot menu to make sure the USB floppy drive
is the first device under Removable Drive.
If the notebook stops responding after booting
Check whether you are connected to a TCP/IP network with no DHCP server. This
can cause a long delay at startup because DHCP is enabled. Contact your network
administrator to determine the proper TCP/IP configuration

***IF THE NOTEBOOK HAS POWER BUT WONT BOOT INTO OPERATING SYSTEM-
Press F2 when you start it to enter BIOS to check your BOOT ORDER to make sure your HD is listed first on the list.
If it is not listed remove it and reinsert it and then try again.. GREAT LUCK!! Please Rate Me, K? Thanks- Lucky4lynn2

remove external peripherals. remove battery. use ac adapter alone. check if ac adapter has sufficient power or check if ac adapter led is solid green or blue. if not then ac adapter might not giving laptop enough power to power up.
if ac adapter led stays on but some problem check the ac adapter - laptop pin socket if loose or damage. if not then replace mobo.

HP DV2036ea i have a blank screen on the computer


Hello there

Description.

When pressing the notebook power button nothing is displayed on the screen or display. The cause of this problem may be a failed AC adapter, the memory modules (RAM) need to be reseated or a failed notebook system board component which will require an HP certified repair.

Below steps will assist in identifying the cause of the problem and suggest the best solution. Test the AC adapter Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board.
  1. Remove the battery and disconnect all external devices from the computer.
  2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
  3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
  4. Press the Power button to start the notebook PC.
If the notebook does not start or the display is blank then check the power indicator light or power socket LED. Check the power indicator light or power socket LED On newer models of notebook PCs, there is an LED or indicator light around the power socket on the notebook. Check to see if this light is on or off, when the notebook is plugged into AC power.The power indicator light or power socket light should turn on when the AC adapter is connected.

  • If the light does not turn on then the problem is most likely related to the AC adapter or the electrical source in your home or office. Go to the Light does not turn on section on this page.
  • If the light does turn on but the notebook does not start or the there is a blank screen then continue to the Light does turn on but the notebook does not start section on this page

The light does not turn on when the AC adapter is connected If the power indicator LED is off, the AC power adapter may need to be replaced. To determine if the AC power adapter needs to be replaced follow the steps below:
  1. Ensure that the AC adapter is plugged directly into a known working wall outlet.
    NOTE: To check the wall outlet, plug in a different known working device like a light, radio etc.
  2. Check all of the following connections:
    • The connection from the power cord to the wall outlet.
    • The connection into the power adapter from the power cord.
    • The connection from the AC adapter to the notebook power socket.
  3. Press the power button again to test the notebook PC.
If the power indicator light still does not turn on, then the AC Adapter needs to be replaced. Contact HP Service and Support for further assistance. Power socket LED or power indicator light is on but the notebook does not start If notebook power indicator light (LED) is on, the AC adapter is working correctly. The problem is a result of a hardware failure in the notebook itself. In some cases, reseating the memory module (RAM) may solve the problem.
