I had to replace a old cable it had a short.! Got a new one nothing happen.!it not charging period.!

Please tell us the make and model number so we can help. Normally a charger does not have a replaceable cable to the laptop - only the AC cord to the power plug can be replaced. I've purchased replacement adapters and the AC power cord doesn't work correctly in the adapter unless I push it in very hard or wiggle it to make a connection. Some replacement adapter also have a plug to the laptop that is not sized like the original and also needs to be wiggled to make a connection. Please provide the information if you still are having problems.

HP Pavillion dv6700 - won't power up

Hello.The most common reasons for power issues are the battery, power jack and power adapter/cord.Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.If you move/wiggle the hp pavilion dv6700 power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.If no change, the power adapter is probably faulty and needs replacement.Hope this helps.

Advent N270 netbook will not charge. Orange light comes on initially then goes off. Also when I wiggle the plug into the laptop the light flashes on and intermittently.

It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

Bought a new power cord because I had to keep moving cord around to get battery to charge, move and would lose charge received new power cord and still have to move cord around to keep getting a charge...

First thing you need to do is STOP trying to wiggle the cord to make it work. You could damage the motherboard.

The power jack needs to be replaced. It's a pretty standard repair. You can try finding a local laptop tech from Craigslist or visit your local shop.

This type of repair usually runs 70-100 out the door (depending on where you live)

I don't recommend you trying to fix it yourself.

ZV5120 pavilion notebook powercord not connecting

You can get an exact adapter from eBay link below, they are quite cheap. Sometimes the break is close to the end of the plug, and sometimes, the actual solder on the socket inside the unit is fractured, causing intermittent connections. Often we are able to use the old cord Plug, and graft on the new power Lead. However it is wired and regardless of how many wires are inside, the is only One - Negative, the OUTER contact. The INNER Contact is Always + Positive, sometimes there are three wire inside, TWO are Plus, and ONE, the shield, is negative.

No connection with the DC Jack on Gateway 3550GZ

It's time to take the computer to a qualified technician, for proper trouble-shooting & repair, because there are very-few "user-repairable" parts inside a laptop/notebook computer.

Won't charge sometimes

I have that exact same model Laptop.

By the sound of your problem I am guessing that the socket for the charger could be worn and not making contact.

Try and ask them just to make sure.

My power cord is loose. It plugs in and charges,

Hello !

If I'm understanding you correctly, the wiggle is from the laptop. Sounds like a problem is about to happen. Your Presario has a loose power jack (connector inside the laptop). It is a part that can be replaced.

If you need further info, let us know.

Hope this helps.

Inspiron E1505 - ac power not always on when plugged in outlet

I've had both the battery and the cord die in my old Dell laptop. Assuming it's like mine and the light is on while the battery's charging and turns off when the it's full....

Dell batteries don't last more than a year or two, so my first question would be how old is the battery you are currently using? When a battery is dying, it essentially isn't able to use its full capacity. So in addition to lasting less than an hour or so, it will try to charge for 6-12 hours trying to get a full charge even though it can't. So the light will stay on until it gives up. It will start charging again if you unplug it and plug it in again. If this is the case, you can either replace the battery ($100+ bucks) or ignore it and don't use the battery.

If the power cord is going, it will only work at certain angles. Play around with wiggling and bending the cord (not TOO far though!!) to see if you can get the battery light to shut off when you move the cord in a certain direction. A new power cord/adapter will cost you around $50 I think, if that's the problem. Let me know if your problem doesn't seem like either of these.

Hope this helps and best of luck!

Screen blackout when using AC cord

I think you're goin to have to replace your" dc-jack" as it's called. This is where your AC cord plugs into your laptop.DC-jack problems are very common in laptops.Over time they wiggle loose just enough to mess up the solder connection on the motherboard.Try gently wiggling your AC cord where it plugs into your computer ,if you screen returns to normal when you wiggle the plug a certain way,then you've most likely got a bad dc-jack.
