Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

Alright, not sure if this will help, by my understanding is that you are saying that when you power the computer using the power supply adapter, nothing comes on? Then when you have your battery installed on, then there are lights blinking from your battery charger LED amount of times. In this case there are no promblem with your laptop and it is your power supply adapter that is damaged and will need to be replaced. It is not charging the battery. The battery is still good, but does not have enought charge to power up your system. You can find a charger on ebay for a good reasonable price compare to getting it from Hp. I hope this can help you.

Laptop will not turn on when i press the on


Normally, if the LCDs light momentarily and go off, then the system is not getting power from the AC adapter (Even if the light is on on the brick)
  1. If another Dell D-Series AC adapter is available, try it. if not check the output for the plug to the system for 19 volts DC, if no voltage, replace the adapter.
  2. Check the connection on the system for cracks or loose connection to the motherboard. If the connector is damaged, then the jack or the motherboard will need replacement
  3. If the system will not power on with a known good battery or AC adapter, then try these steps.

It will not turn on even when plugged into mains


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.
