Sounds like a failing battery. Why not email Dell support and ask them.

When you plug in the power cord is there anylights whatsoever on the laptop, where the plug goes in or on the AC Adapter ofthe power cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

Hi,

The battery is discharged, you would need to charge the notebook. If the power is plugged in and still the issue is there. Remove the batter and connect the power cable without the battery and turn on the notebook (without battery). If it turns "On" the battery has gone bad.

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.

It has enough juice in the battery to light up the lcd lights but not enough to turn it on. Could be the power supply. Consult a reputable service center and have it checked out. Good luck.

ok, take the battery out and leave it unplugged for a few hours.  Only plug the ac adapter in after.  Press and hold the power button for 10 seconds.  Does it still do it?  If it does work, then chances are your mobo has bit the dust or you have knocked loose an internal charging part.

If it's blinking 9 times then it's likely telling you one or more of the RAM sticks are in need of replacement. To check these, remove the laptops power cord and battery, then locate and remove, the cover for the RAM. Remove one chip at a time and try booting the laptop.
