Laptop will not turn on

Regarding your question you could try a power discharge for your device:
- disconnect the AC adapter
- unplug the battery (if detachable)
- press and hold down the power button for 30 seconds (to discharge the components)
- plug the AC adapter only (without the battery if it is detachable)
- turn on the unit

If the battery is not detachable, please follow the procedure with the battery attatched.

- turn off the unit
- disconnect the AC adapter
- press and hold down the power button for 30 seconds (to discharge the components)
- plug the AC adapter
- turn on the unit

If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.

1. Disconnect all peripheral devices and remove all USB devices and 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 .
3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
4. if still there no sign of life then send it to nearest service centre

Disconnect all peripheral devices, 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. Then reconnect the AC power adapter (but do not insert the battery), press the Power button, look for glowing Light Emitting Diodes (LEDs) near the caps lock and num lock keys, and listen for sounds of a fan or other moving parts turning.

Could be the Ac -DC adapter is faulty .
Suggest taking laptop to where you bought it and asking if they can check it with a different Ac-DC power adapter .

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.
     • If LEDS do not glow and the fan or hard drive do not spin, AC adapter may need to be replaced.
     • If LEDs glow and PC boots, the battery 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.
   • 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.

There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.
To verify this, unplug your laptop & try to run it on battery only. Watch out how long it will stay on (if at all). If it didn't work on battery alone, or worked but for a very short time, then your battery is defective.

Hi, Shutdown the system , and disconnect the battery from the laptop.Also disconnect the Ac adapter. There is a button the battery , press and check if there are any light the glow on the battery. If there are no lights that glow the battery is dead.
Press and hold down the power button for 10 sec. after removing the battery and the Ac adapter Reinsert the battery and connect the Ac adapter 1.Power on the system and tap on f2key slowly five to six times on the Dell logo screen 2. You would enter the blue screen 3. Using your down arrow key, go to the option that says battery info or battery health . Check if there are any error messages on the same. If the battery is not detected you would have to replace the battery
** Note ** normal life expectancy of the battery is one year.

Hi,
Verify the AC power adapter displays a solid green or blue light. Older Latitude™ C Series laptop computer AC adapters may not have a light.
Run the diagnostics on the system as follows , connect both the battery and the Ac adapter before running the diagnostics

1. Ensure the system is powered off.
   
2. Remove all external peripherals.
   
3. Press and hold the <Fn> key on the keyboard.
   
4. Continue to hold the <Fn> key while pressing the power button.
   
5. Release both buttons.
   
6. Note which lock LEDs are lit (lock LEDS are next to the power button)
   

And proceed with the troubleshooting steps listed below

Hi,

This usually occurs when the AC adapter is failed.

Look at the port where it plugs in, if it's glowing blue the adapter is working, no light, it's dead.

If it is dead, you will need to buy a replacement. If it's working then the problem is elsewhere in the laptop. Being you have tried resetting it already it's likely a hardware issue and may need to go to a pro.

Let me know if the AC plug has the blue light on and I'll see what other help I can offer.


Hope this helps FixYa,

Chris
