Compaq Presario Laptop AC Adapter Plug

The silver part with yellow ring on the plug that goes into the laptop has come off. I can put it back on yet it won't have a silid connection into the back of the laptop.

Is there a way to fix this without having to buy a new AC Adapter?

Please 1. unplug the ac adapter, detach the main battery, press the power button for 15 seconds, plug in the ac adapter, and restart your laptop. If the problem persist: 2.unplug the ac adapter, detach the main battery, press the power button for 15 seconds, take out the hard drive, plug in the ac adapter, and restart your laptop. If the problem persist, then it means that the laptop motherboard is dying. Please read your laptop's service manual before you open the laptop's case/body.

Just got cq56-115dx laptop this morning. turned it off after setting it up. Turned it back on and only have blank screen. Power shows lit up.


Hi.

Remove the AC power (charger) and then take the battery out. Plug in just the AC power supply and turn the laptop on, see if it boots up and shows a display on-screen. If it boots let it boot up and then shut it down as normal. Reinsert the battery and try as normal.
If you still get a blank screen can you then tell me if you get any post (splash) information like the Compaq Presario logo before it goes blank.


Good luck.

Hello The mandatory requirements before you try anything else are the main battery must be installed, it must work correctly, and there must be nothing wrong with the AC adapter or it's connection to the laptop. -Your model is recent enough the main battery must be installed - it won't start up on the AC adapter alone. - The main battery must be capable of being charged up to at least a minimal capacity. - The main battery does not last forever. Typically it works as it should for a year or so then begins to deteriorate - by the second year it can't be charged to anywhere near it's rated capacity. It gets worse as time goes by. Older batteries often develop internal shorts that makes it impossible for them to produce the voltage they're supposed to produce (you can test for that with a volt meter), and they may get HOT when you attempt to charge them for a while, rather than a little warm, or they may never get warm at all. - If you haven't replaced it since the computer was new, this model is old enough the main battery should be replaced! There must be nothing wrong with the AC adapter or it's connection to the laptop - if there is, the main battery cannot be charged properly. A common thing people do when they unplug the AC adapter is to pull on the cord rather than the plug on the end of the cord as they are supposed to do. Doing that eventually damages the plug and/or the wiring near the plug, and over a longer period of time, doing that damages the jack in the laptop the plug plugs into. The jack in the laptop should move when you wiggle the plug in the jack. Most laptops have an led that lights up only when the AC adapter is plugged in, there's nothing wrong with the AC adapter or it's connection to the laptop, and the AC adapter is charging the battery. That led should come on at least briefly when you unplug the plug from the AC adapter, then plug it back into the laptop jack, even if the main battery is fully charged. The led should not blink on and off randomlyIwhen you wiggle the plug in the jack. If that led never comes on, there is something wrong with the AC adapter or it's connection to the laptop, or the main battery is shorted (check it's voltage). If that led never goes out even after a long time, the main battery is probably no good - replace the main battery. The plug on the AC adapter cord can be replaced, but if you damaged it by pulling on the cord you will probably continue to do that at least part of the time, so since a plug molded onto the cord stands up to abuse a lot longer than a replacement plug, it's often a better idea to replace the cord from the AC adapter to the laptop if it can be unplugged at the AC adapter (a laptop repair place may stock that), or if that can't be done or you can't find that part, replace the AC adapter. The jack on the laptop can usually be replaced but that requires taking apart the laptop and careful removal and replacement of the jack. A laptop repair place does that sort of thing frequently, and often have the more common jacks in stock, though they may have to order one. Hope this helps, if so do appreciate my effort by rating the solution Good Luck, Cmptrlink

Windows failed to start.


Try a hardware reset: remove the battery and unplug the AC adapter, press and hold the power-on button for at least 20 seconds (it will discharge the internal capacitors), then put the battery and plug in the AC adapter. Try to press the power-on button again.

My Compaq Pres V2000 laptop does not get on with power on switch


Take out the battery and only hook up the AC Adapter to see if the laptop turns on. If it does then you know the battery is shorting out the laptop and either has very little power to turn on the laptop or is shorting out the laptop cause its bad.

If you don't get the laptop to turn on, make sure your using a well known working wall outlet to plug the laptop to and only use the AC Adapter. If you AC Adapter is hooked up and the Green Led turns on then you know the adapter is good.

After those two steps, you can also try taking out the dvd drive and the hard drive. Then try turning on the laptop and if the laptop still doesn't turn on then the motherboard is bad in the laptop.

Will not work with ac power adaptor but does with


Did you wiggle it a bit when plugged in? You can't tell from looking on the outside if the plug is fine because it goes bad inside where it is soldered. This is a very common problem, and have fixed many laptops with the same problem. All of them had a bad solder connection inside. Did you dtermine the plug was fine by plugging another ac adapter to your laptop or you just checked it visually? Hit me up I will solve this one for you.

Computer shut down


The sparking has probably caused your circuit protection inside the AC adapter to turn off the current.
Also, when you are plugging an adapter in,,do not have it plugged into the wall power outlet when plugging into the laptop,,,plug into the laptop first and then plug into the wall.

Compaq Presario 1200 won't charge battery


dear N9YK

you can follow this

If you have a loose connection where you plug in the power on your laptop, or it works intermittently, you could have a bad dc jack. Symptoms
  • Move the power plug and the laptop loses connection
  • Broken or cracked dc jack
  • Laptop won't charge but worked on battery
  • Power LED and battery LED flicker when the adapter tip is moved
  • Battery won't charge
  • Sparks come out the back of the laptop
Why does this happen?
  • Flaw in manufacturer designs
  • Use of universal or non-original ac adapter
  • Lots of plugging and unplugging of the ac adapter
  • Tripping on or pulling the ac adapter cord
or you can check your dc amper in your adaptor

oke

Compaq presario V2000 doesn't start


It sounds like one of the most frequent failure for a laptop, the plug on the back of your laptop is probably broken. Check if it's loose, try to move the plug until you get the orange light. If it's the case, someone need to resolder/replace the plug on the motherboard.

Hope this helps! Let me know how it goes.
