    just to clarify, what is the power supply that you are using?
    I thought I had a dodgy socket, went thru the trouble of replacing said socket on a different model laptop. It turned out that the 3rd part psu I was using had a design fault in that the adaptor, after a while lost contact with the power cable on the psu, causing laptop to shut down.

Hi, the charging connector is broken, can it be replaced easily? If so , how do i get to it? the lap top is a TJ74-RB-050UK. Cheers


the dc jack (charging connector) can usually be bought for about 5 pounds or less from ebay. As far as fitting it goes it depends how confident you are. You will need to disassembel your laptop and remove the broken jack from the motherboard and then solder the new one on.

WOW, not such a easy fix. Lots of screws, tricky to open.
HP Laptop Power Jack eBay Make sure you get the HP model number off of the Jack socket - It will be labled. Good luck and have a great day. Jack shown may not be the same to your model of laptop.

My laptop power cord had a broken/bare wire problem while plugged into laptop. The laptop made a popping noise and blacked out. No power through the unit. Doesn't respond to powering up. I have a new...


Hello scorp,
Wish i could give you better news, but more then likely the entire main board will have to be replaced. It is possible that the power jack may just need replaced, or re-soldered. If you are lucky enough to have a model of laptop that has a separate board for the power jack then can go for around $60, the jacks them selves a few dollars. That said assuming that the battery had somewhat of a charge it should have powered up regardless.
Best advice I can give you is to replace the main board, and keep in mind that there is a reason most of us avoid refurbished hardware.
Good luck

Only getting intermittent power supply when AC adaptor plug in,power can be ma to come on by gentle movement of the connector in the laptop socket?


You need to replace the DC Power Jack on the motherboard, of the LAPTOP.

What is the LAPTOP manufacturer name, and Model Number?

Acer power supply problem


Yes but it is expensive. The motherboard has to be removed from the laptop. This is a common problem in that the jack comes loose from the motherboard.

Power cord cuts in and out


There are two places the trouble can be happening, at the adapter plug or at the power jack in the laptop. To determine which one is causing the power loss, hold the plug in the computer steady with your fingers while you wiggle the adapter cable. (If you have access to a voltmeter you can measure the voltage at the plug while you wiggle the cable to see if remains steady.)

If the charge light flickers it's the adapter cord that's bad. Because the wire flexes so much at the plug, it can break inside the insulation and cause the power loss. You either need to replace the adapter or repair it by cutting off the bad end and installing a new plug.

If the charge light remains on with the plug held steady but flickers when you wiggle the plug itself, the trouble is on the main board in the computer. The solder connections at the power jack have broken from the plug flexing and need to be repaired. This involves opening up the computer and getting at the solder side of the main board. It's tedious but relatively simple. If you are not experienced with soldering on small electronics, leave this to a professional shop.
