    Hi kirkmiller
    the green light comes on for a few seconds when I first power up the laptop then it changes to orange.Yes the light changes to green again when the laptop has been powered up for quite some time and the battery is fully charged,the laptop is working fine, however until I used a new power supply which I strongly suspect was faulty the green light was on permanently I had never seen the orange light before this

    Thanks Kirkmiller for your help,as I had not seen the orange light in the past I was concerned there was a problem that might damage the laptop

    if you leave the power supply plugged in, AND the battery installed will the orange light eventually turn green? Does the computer work fine with the orange light on? (It should).

On Mac iBooks the orange light comes on when it charges the battery. Once the battery is charged it turns green. Im guessing the other powersupply was aftermarket or broken. EIther way, if it starts out green - recognizes the battery isnt full - turns orange for a while - then turns green when the battery is full, then the computer and powersupply are working perfectly. Enjoy your iBook!

Hey my compaq labtop battery wont work i tried everything like charging all night -nothing please if you know how to fix this please e-mail me at jessezink@yahoo.com


The battery may have a failed protective device inside of it. If it new, the battery should be covered by warranty.

When the battery is installed in laptop and charger plugged in, there should be a light on laptop that lights up to show it is plugged into a charging source/ power source.

if the light does not light, see if it will light up with battery removed from laptop. If it does not light up, and you cannot power up the laptop- the power supply has failed.

My dell dccy will not power on. It was working fine and was powered off but will not power back on. I have checked the power cord. I have opened the case and reseated all connectors. Pushing the power on...


Yes, it's called bypassing the Power On switch. Has nothing to do with the switch itself, or it's wires.

You use a jumper wire on the 20 or 24-pin ATX main power cable's connector.
Touch the jumper wire from the Green wire (Soft Power On) to ANY Black wire. (Ground)
(Soft Power On is abbreviated as PS_ON)

If the Power Supply comes on, the problem is the Power On switch.
If the Power Supply does Not come on, the problem is the Power Supply.

1) 20-pin ATX main power cable,

2) 24-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Look at the photos of the ATX main power cable plugged into the motherboard.
Where the wires go down into the connector is the Back of the connector.

This is where the jumper wire goes down into.

The jumper wire goes down into the socket hole, in the Back of the connector, RIGHT NEXT to the wire IN the socket hole.
The jumper wire has to go pretty far down in the socket hole.

[ATX power cable plugged into the motherboard, Power Supply plugged into power ]

At the end of every wire in the ATX main power cable's connector, is a metal terminal.

A Female Molex Crimp Terminal connector,

http://www.alibaba.com/product-gs/336134982/molex_female_crimp_terminal_connector/showimage.html

[You can click on the Zoom In icon { + } at the top to enlarge the view]

The jumper wire Must touch that metal terminal.
The jumper wire is made from a straightened out paper clip, bent into a U shape.
The middle of the U is wrapped a few times with Black plastic electrical tape.
This where your fingers hold onto the jumper wire.

(One wrap of Black plastic electrical tape is good for 600 Volts DC)

One 'leg' of the U shaped jumper wire goes down into the socket hole with a Green wire.
The other 'leg' of the U shaped jumper wire goes down into ANY socket hole with a Black wire.
(ALL Black wires are Ground wires)

The contact period made is no longer than 2 seconds.

The Voltage is 5 Volts DC.
Two flashlight batteries produce 3 Volts DC.

This is one generic ATX power on switch that I have found fits many computers,

http://www.directron.com/atxswitch.html

NOTE*

WATCH IT when buying an aftermarket Power Supply for your computer, if it needs one.
For a time period Dell was strictly a Proprietary computer manufacturer.
Dell wanted THEIR parts used in THEIR computers only.

They had the motherboard manufacturer switch the pins around in the ATX main power cable connector, on the motherboard.
They also had the Power Supply manufacturer switch the power cables around in the Power Supply.

This means if you plug an ATX main power cable, from an aftermarket Power Supply, into one of these proprietary Dell motherboards, you WILL fry out the motherboard!

Can also fry out the Processor, Ram Memory, and Harddrive. (Plus a graphics card if you have one installed)

CHECK the color code of the aftermarket Power Supply's ATX main power cable, to the color code of the Dell power supply.

See that the color code of the wires matches the socket holes in the connector.

Gateway 500s power box when hitting test button powers both fans, but no power to hardrive, dvd, or monitor. I have replaced power supply, motherboard, and harddrive, I have nothing, but green power button...


Does the fan on the power supply run? As you say the power on switch lights up and so does the motherboard, means that the power supply is working. Monitor gets power from the socket on the power supply. Try plugging it in the wall socket. Try to unplug the main power cord from power supply to the motherboard. The one that has a broad plug at the motherboard end. Replug it and they power on the PC.

Dell computer was working and i turned it on next day and it was dead no lights or noyhing


If your computer is under warranty, I'd suggest you contact either the Vendor where you bought it, or the Dell support site. Either should be able to acquire a new power supply and install it for you free of charge (if under warranty).

Some other thoughts though, before you do that. If there are no indicators that your power supply has died (smell burnt electronics, any weird buzzing sound prior to the computer not working, etceteras), then you might want to check the connections to the wall socket, the connection to the PSU itself, and even test the circuit breaker for your socket (some wall sockets have test / reset buttons that cut the power during surges).

Asus ac adapter will not wrk green light on adapter


First check the wall socket make sure you are getting power, plug a lamp into it for instance. If there is no green light on the adapter then it is bad and you will need to order a new one from your computer manufactor.

Acer Aspire 7004 wmsi Will not start.


When you press the power button does anything happen? such as lights or LED's illuminate?

You could try the following -

1. Make sure there is nothing plugged into the computer (USB devices or memory cards etc etc).

2. Remove the power cable & the battery

3. Press the power button for 30 seconds

4. Insert the charger but not the battery and try and start it up.

If that doesnt work check the USB ports for damage and the port where the charger is plugged in aswell.

If they are damaged or it still wont start it will probably need repairing.

Orange light on instead of green light..also 3 and 4 number light up


When I first started repairing things a mentor said always unplug anything you are working on. I found this to be a number one rule. You just don't know what still has power even though it says it's off. I've made this mistake too by not checking.
Okay. So...
Hopefully the power supply is just shutting down due to a drain on it's voltage and will be okay. Take out whatever you tried to install. Try it again. Take out anything not necessary to boot your computer. You'll need the video card if not integrated. If you have a bootable floppy, Unplug the hard drive. See if you get to a screen where you can go into the bios setup mode. You also might want to write down where things go back. This is especially if doing this with little sleep. Let me know..'ask me.'
