There realy is nothing you can do with that short of buying a cable end and reterminating it yourself. The keyboard is still under store warranty. Turn it back in and get a replacement.

My desktop computer loses power when I plug the 4 prong power connector into the motherboard. I have tried a new power supply but it does the same thing


Maybe we need more information. The motherboard needs that connector. Is it disconnecting physically? Check the plastic clasp that hold it in place. Be sure the large ATX connector is connected properly. Unplug then plug it back in.
What do you mean by it loses power? Are the fans running when it is plugged in? Do the fans run when it is not plugged in? Try unplugging everything except your video card, CPU, RAM, and keyboard. Plug the ATX connectors in including the 4 prong one. If it still doesn't work check your capacitors. They are the cylinder looking cans soldered on the motherboard. Are they bulging or leaking? Might be time for a new motherboard. Good luck.

I purchased an emachines a few years ago but continued to use the keyboard that I was familiar with. It is now worn. I have installed the new emachines keyboard and nothing happens...no lights come...


Did the old keyboard plug into a PS2 keyboard socket (round purple connector) or into a USB port (flat rectangular connector)? Similarly, what type of connector is the new keyboard?
If it is the round PS2 connector you may have connected into the green PS2 mouse socket instead of the purple keyboard socket. Although the sockets are similar, they work differently.
If it is USB, then try moving it to a different USB port.
Try the keyboard on another PC.
If you cannot get it to work then replacement keyboards are very cheap.

Keyboardbroken..must hold keys down ,makes clickynoise,after 2nd click,letterappears,or functionoccurs


I recommended that you connect either a known good keyboard or a new one to your computer and see if that fixes the problem. Keyboards are not at all expensive and they are not worth fixing.

If the problem continues after you replace the keyboard, the keyboard controller on the motherboard is bad and you are faced with replacing the motherboard.

HP G60-458DX shutsdown when display is moved.


To me a direct indication that the Display Panel Cable connector is loose, or damaged pbthomas.

The connector on the Inverter side most likely. Or again, the cable could be damaged.

The Display Panel Cable could have been pinched, or the wires inside the cable could have been stretched causing them to break, and touch each other. If stretched the sheath of the cable may, or may not, show visual signs of damage.

Since the Display Panel Cable leads from the motherboard, (Under the Keyboard), up along the left Display Panel Hinge, and into the Display Panel Assembly, then connects to the Inverter, it would be feasible for this damage to occur.

Probably right at the Left Hinge area.

The HP G60-458DX is one of the HP G60 series of Notebook PC's.
Allow me to show you the Display Panel Cable, it's location, and how to access it,

This link takes you to a website where you can download the Service Manual, for the HP G60 series of Notebook PC's, for free,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-compaqhp

On this page go down to the 13th line. The one that starts with G50.
Scroll across, and click on > G60

This is a PDF file. Allow time for it to download. Average time is usually around 5 seconds to see the first page come up, and an additional 40 to 50+ seconds for the file to fully download.


Ignore the following if you are aware;

The Page Number box is at the top of the PDF file to the right of the blue Down Arrow.
If you know the page number you want you can use one of two methods to go to that page.

1) Use the blue Down Arrow to go page by page,

OR

2) Put your mouse cursor in the page number box.
Left-click once
Type the page number
Press the Enter key

Go to Page 63.
Item 3 points to the Display Panel Cable.
(You can enlarge the view size by clicking on the Zoom In icon at the top of the PDF file.
It's the circle with the Positive symbol in it ( + )

Go to Page 66.
The second illustration down, again shows the Display Panel Cable, in Number 13.
The Display Panel Cable is indicated by item 2.


To access the Display Panel Cable:

A) To just access the Display Panel Cable on the motherboard side:

1) Remove ALL power to the laptop. Remove the AC adapter (Charger) and Battery
2) Observe Anti-Static Precautions. (Page 41. Grounding Guidelines)

3) Remove the Keyboard. Page 56
4) Remove the Keyboard Cover. Page 59

[NOTE on removing the Keyboard, and the connector AT THE END of it's flat cable.

The Keyboard cable is an FFC. Flat Flex Cable. It does Not have a connector attached to it.
The connector is mounted to the motherboard.

The Flat Flex Cable comes out of the connector on the motherboard.
Just a flat cable made of a flat plastic sheath, with copper wires going through it.

Only one side of the plastic sheath is exposed, for the bare copper wire endings to make a contact.
The flat flex cable must be reinstalled in the direction it came out.

The connector on the motherboard is a Zero Insertion Force connector. (ZIF) It may be thought of as a plastic rectangular block, that is two separate pieces, however it Does Not come apart in two pieces.

One of the two pieces slides away from the other one.
The larger piece stays attached to the motherboard, while the upper smaller piece that faces the LCD screen, moves.
The upper piece only slides so far.

When the two pieces are squeezed together, they pinch the flat flex cable, and lock it into position.
When the connector is opened, or the upper piece is slid away from the larger stationary piece, the flat flex cable is released.


B) To access the Display Panel Cable on the Display Panel side:

Follow 1 and 2 above.

The Display Panel must be removed, and opened.
The Display Bezel is removed to access the other end of the Display Cable, which is attached to the Inverter.
Page 62

If it isn't obvious that the connector is loose on either end of the Display Cable, then the Display Cable should be tested with a multimeter set to OHMs.

{An economical multimeter can be purchased for around $10 to $12. Most auto parts stores carry them, as well as a multitude of other stores.

The multimeter function knob is set to OHMs.
The Positive (Red) probe lead goes into a socket hole, in the connector at one end of the Display Cable.
The Negative (Black) probe lead goes into a socket hole, in the connector at the other end of the Display Cable}

You should get continuity from one socket hole at the end of the cable, to the socket hole at the other end of the cable. (Needle on meter face of multimeter will move)

If it isn't obvious as to which socket hole on one end, matches up to a socket hole on the other end, hold the probe in one socket hole of one end of the cable, then test each socket hole on the other end of the cable, with the other probe.

Note*
Only one socket hole at the other end of the cable should show continuity.

If more than one socket hole at the other end of the cable shows continuity, you have two broken wires touching each other.

Check the continuity of each wire in the Display Cable.
Wiggle the Display Cable when checking for continuity to see if there is a break.

No continuity through a wire, or an intermediate continuity, (By wiggling the cable), means the Display Cable is bad. Replace.

This pictorial guide should also help you in removing the Display Panel,

The Display Cable comes with the Webcam Cable as a kit.
HP part number > 496841-001

This is an example of the kit,

My keyboard stopped working


What kind of keyboard connector does it have?

If the end of the connector is round with pins (serial connection), just plug the keyboard back in and reboot the computer. With that style of connector, if they get knocked out or come loose while the computer is running, they will not always work again until you reboot.

If the keyboard uses the flat plug (USB) connector, the computer should be able to pick it up again without a reboot when you reconnect it. Also note that if the keyboard is USB and it stops working; if you have any other USB items hooked up as well (IPod, webcam, external drive,etc), check to see if any of those devices are still working either before rebooting your system. Sometimes, another unrelated USB device may crash causing ALL USB devices to fail simultaneously. If this is the case, unplug all USB devices except your keyboard and reboot. If the keyboard works again, reinstall all of your other devices one at a time until you locate the one that crashed all of them (if that was the case).

Hope this helps.

USB Keyboard and mouse wont work with PS2 KVM with adapter


Have you tried rebooting once it is connected? Not sure if it makes a difference, but I know you can not hook up PS2 peripherals without rebooting.

Can't hook up mouse and keyboard


Okay, setting up the mouse and keyboard is very simple. The mouse should have a green end, and the keyboard has a purple end. They fit into the corresponding places in the back of the computer. Also both the mouse and the keyboard have flat sides. Try attaching them in the four different directions (e.g; up, down left, right). If that still doesn't work have them look at the wires to confirm that the wires are not bent, that could explain the problem, because the twisting could have caused bends in the PS2 Connector.

Keyboard failure and diskette drive 0 seek failure


How old is the computer, could it still have warranty? USB ports are often protected with fuses. Some latest stuff has resetable fuses, but many are one-time that do not heal. Did you try the keyboard in the front USB's The thing of biggest concern though is that this happened in coincidence, meaning you may have a motherboard hardware failure. (the reason I mentioned warranty)

I have an ACER Travelmate 230 notebook. The system is working but the monitor does not display anything. I can use the laptop with an external monitor successfully. Is this the end for my laptop?


So after a power up we can deduct that its not a hard drive problem because you have managed to successfully attach an external LCD screen to the system.

It may not nessacarily be the end , laptops are mobile machines and time to time plugs and sockets don't hold their devices in place and in your case most probably one of the two connectors on your laptops LCD screen.

It could possibly be one of these 3 things

1. The ribbon connector which carry's the video signal to your LCD screen has become dislodged you will need to open up your laptop and check this and make sure its seated in its interface properly. This is usually located in the spine of the laptop

2. The power connector on the LCD screen itself which is a small black 3 pronged plug has become loose also open up your laptop and check this

3. when the computer has had time to boot press the fn + F6 on your keyboard , you may have to press this a few times but this is the manual LCD screen off and on button

Tell me how this goes

Cheers
