Compaq notebook evo n1020v won't power up. Battery charger is brand new.


Remove the main battery, now try power on, if okay the battery needs to be replaced. Sub out ram one at a time to see if you can start it.

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.
  1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
  3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
  4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
    • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
    • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
    • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
    • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
      • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
      • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
      • If LEDs glow and PC boots, the AC adapter may need to be replaced.
      • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

I have a Compaq N1020v with a 14.1 display. The LCD was cracked and I plan to replace it. I would like to replace it with the 15 inch display for the Compaq N1020v. Will that work, or is the 15.0 to big?


It depends on how "adaptable" the mounts on the "surround" of the LCD screen, i.e., whether the one "surround" was used by COMPAQ for both 14" and 15" LCD screens, or whether the part-numbers were different.

My laptop will not turn on


Try another AC Adapter with the battery taken out of the laptop. If the light still blinks then that means the motherboard is bad and would need to be replaced.

BLANK SCREEN ON MY hp compaq nx9420. my laptop was working fine and then when restarted I got a blank screen. The power LED and cahrging LED both light up but screen remains blank. have changed the video...


Did it display any video at all with boot options or HP logo? Any POST test or beeps after you started the laptop?
Try removing the power ac adapter and battery. then only boot it up with just the AC adapter (no battery).
Good Luck, JAJ

My compaq evo n1020v freezes,on restarting blank screen


First conclusion: This is not a software fixable problem. If your notebook is still in warranty, I suggest you to RMA it. No doubt somethings broken.
