SOURCE: computer wont start
I ran into the same problem with my Armada E500. In my case, it was a faulty RAM module. What I would suggest is start by removing the battery, and the charger. Then continue by removing the plastic section above your keyboard (there is a single screw holding it in place on the rear end of the laptop. This plastic covers the right-hand hindge) from there, there are four plastic tabs that you slide down to remove the keyboard. This will give you clear access to the ram. Remove the module(s) and, using a soft eraser, gently clean the contacts. If your laptop has two sticks of ram, I would also recommend putting them in opposite ram slots. After that, replace the keyboard and plastic bezzel, reconnect the battery and charger, and try to boot it up again
SOURCE: Nextar MA 166 MP3 Won't Charge
You have to install the software for the mp3 player BEFORE connecting the mp3 player to the computer, or else Windows XP will override the native drivers. That particular Nextar is not compatible with Windows Vista, so you may have a problem if you have a newer computer.

Make sure the hold/lock is not engaged first.
Triple Reset for Philips’ GoGear:
Disconnect the Go Gear from computer. Press the reset pinhole until the player turns off. Hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard. If this pop-up does not appear, reset the player again WHILE connected to the computer. Open the Philips Device Manager, and go to Repair Tab. Reset the player one more time while connected to computer. Follow the repair instructions.
After repair is complete, upgrade the firmware for this player. Will erase all the songs, but you should be good to go again.

This happens when the battery will not hold a charge. You will need a replacement battery if you want that light to go away.
If the battery has not been like that too long
put in a plastic bag and freeze overnight
let thaw until room temp
insert battery
plug in jack
do not power on laptop
let charge for1 hour
then try

I would bypass the Power On switch with a jumper wire on the 24-pin ATX main power cable's connector, and see if the problem is a $5 Power On switch, or the Power Supply.
Ready?
This diagnostic test does Not involve the Power On switch, or it's wires. There is no cutting of the insulation of ANY wires.
You need a paperclip.
Follow Anti-Static Precautions.
Anti-Static Precautions;
Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static BEFORE reaching inside your computer.
Computer on a table, computer unplugged from power, computer case open;
TOUCH an unpainted surface, of the metal frame of the open computer case.
This action will relieve your body of Static.
IF, you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.
Top View of the motherboard, no power cables attached, no hardware attached,
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01324212&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3692730
The 24-pin ATX main power cable connector for the motherboard, is on the right side of the Ram Memory slots, and next to the outside edge of the motherboard.
Whitish in color, two columns of 12 socket holes.
This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,
http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24
Viewing the photo all the way to the right, note that the 24-pin ATX main power cable is plugged into the motherboard. This is the way you want it when testing.
(NOTE* Color of connectors does NOT matter)
Note the Green wire.
The Green wire is the Soft Power On wire. Abbreviated as PS_ON.
Note the Black wires. -> ALL Black wires are Ground wires.
A paperclip is used to Temporarily, touch the Green wire to ANY Black wire.
(The Power On switch is a Momentary Contact Switch)
The paperclip is bent into a U-shape. The top of the U is wrapped a few times with black plastic electrical tape.
This taped area is for your fingers, and thumb to hold onto.
Turn the U-shape over, and it is the 'legs' that you are going to use.
One 'leg' of the U-shaped jumper wire, is inserted down into the socket hole with the Green wire.
The Back of the 24-pin ATX main power cable's connector, is where the wires go in.
This is the side the jumper wire leg goes in.
Goes RIGHT NEXT TO the insulation of the Green wire, slides down into the socket hole, and touches a metal terminal at the end of the wire.
The leg of the U-shaped jumper wire, has to go down in the socket hole pretty far. (3/8ths of an Inch?)
It MUST touch that metal terminal at the end of the wire.
[ This is an example of the female metal terminal I am referring to,
http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US
The left side has tangs (2), that are crimped around the insulation of the wire. The Right side is the front, and you can see the front tip of them in the center photo of the Playtool link ]
The other 'leg' of the U-shaped jumper wire, goes down into ANY socket hole, that has a Black wire in it.
Bend the paperclip, attach tape, then try it in the two socket holes.
(Green wire / Black wire)
Once you have it bent to fit, and have tried using it, remove, and plug the Power Supply into power.
Now use the U-shaped jumper wire.
The contact time is no more than 2 seconds.
Concerned about getting shocked?
The Soft Power On circuit uses 5 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.
NOT saying there may be a small spark!
You may wish to use a glove on the 'jumper wire hand'.
Power Supply comes on? You have a bad Power On switch,

Power Supply does NOT come on? You have a bad Power Supply.
