Question about HP Pavilion dv4000 Notebook

6 Answers

The laptop won't power up

It was setting on a tray in the spring and was knocked to the ground while plugged in. The power cord was bent at the connection point and my husband assumed it just needed a new power cord. It has been dead for several months now and we just went and finally got a new universal adapter for the laptop. I've plugged it in, making sure to use the correct adapter but we still have no power. It's only been about 15 minutes, do we need to leave it plugged in a little longer or is that just wishful thinking?

It's an HP Pavilion DV4000.

Remove the battery from the laptop and try to start it on AC power only, this will eliminate the possibility of the AC adaptor on the laptop hasn't snapped
post back please

Your chances are pretty good that the jack just is loose and not actually broken, however replacing it is better. It's usually something that can be repaired at home by a tech savy person, the part is readily available on Ebay. I work for a Laptop Repair Shop in NYC and we deal with this issue frequently.

Have you checked the power pin? Chances are pretty good that wither the small feet where the pin assembly is soldered to the motherboard or the center portion of the pin itself has been dislodged.

Repairs aren't that tough, just tedious. The part itself (the pin assembly) can be found on the web for $10-$20. Be very careful (and take notes) as you disassemble your laptop. And get a good cable retention device so it doesn't happen again.

Wishfull thinking I'm affraid, When plugged on, it will normally power on right away when you press the power button.

What kind of adapter did you get. You cant use any old one, you need to have the right connector and the right power output. If its working, you should see a green or red light on the laptop light up. The adapter needs to be the right voltage or it wont get enough to charge or power it.

Also, when it fell and bent the original adapter, the connector may have been damaged on the laptop.

Is it a round adapter that goes in, or does it have little Pins inside where it plugs in?

Check to be sure there arent any damaged pins.

The shock may have damaged the mother board.

It should still run on battery power though if the battery was charged at the time of the incident.

Let me know.

If you have a voltage meter test to make sure that you are getting the correct voltage to the laptop. The battery should tell you what the correct voltage is. If all is this ok, try to powerup with out the batery in place.
Hope this helps

I am sorry to report, that's wishful thinking. More than likely, the plug receptacle internal the laptop is broken. I'm sure your power supply/power cord is fine. If the laptop is not too old, and is still worth money, I would take it to an electronics repair store and have then repair it. If it is old or the price of the repair from the electronics repair store is too high, then sell the laptop. Someone will buy it.

You may want to ask around to your friends, and see if anyone is familiar with soldiering or electronics. They may be able to fix it fore you.

Good Luck!

Hp laptop won't power on


Hello. It sounds like either...

1. Your power adapter is damaged/not working. Look and see if a LED is illuminating on the power adapter. If it is chances are it is working fine and the problem may lie on your laptop. If not replace it. The easiest way to tell if your power adapter is bad is to go out to Wal-Mart or your local technology store and purchase one of their universal power adapters. They are expensive but you can buy it, try it, and return it if it does not solve the problem.

OR

2. The DC pin on your laptop is bent/broken/loose. Look at where your power adapter plugs in on your laptop. Get a paper clip, bend it out to make a long paper clip and slightly push its tip on the pin inside your laptop. If the pin moves chances are either the DC pin needs to be soldered down or needs to be replaced. The part is usually cheap around $10 but the labor can cost more than $50

Hi my acer desktop sometimes refuses to switch on and other times it switches on. When it accepts to starts, it sometimes switches itself off when am working. What could be the problem?


Could be a combination of things causing this, "What to Check Out" first off it may be the power button it may be worn and in need of replacement. Second could be a short in the power pin input where you plug the laptop in at. Plug it in when working or not working and wiggle it around gently to see if it lights up or sometime shows a blinking light. If this happens then you will need to have that piece on the board replaced or soldered. Check for shorts in the wires itself see if there are bent wires or crimped up wires on the power cord. Animals are notorious for doing that sort of damage to power cords.
So we know it is a power issue working and not working that is where I would start at. The sources as I explained above. Right now it is something that is shorting out. I believe without seeing the computer itself that the plug in power sources are the issue here. Especially the input plastic pin where you plug the power cord into is a common issue on laptops because they get bent or stepped on or pulled and twisted when using a laptop.
This is why it is critical to be gently with these types of components. Keep animals away from chewing on them as well or when plugging laptops in to make sure the cords are not bent up or twisted but straight inline with the power source plug in on the laptop. This can happen over time as well.
I think that is your issue. While laptop is being repaired if you do it yourself which I do not recommend if you have never done this sort of thing take it in for repairs. Make sure they clean the dust out of the fan and CPU areas as well. John

It sounds like the spring mechanism on the tray is either bent or broken. You can try removing the tray and bending the spring steel to increase the friction or you may have to purchase new or used ash trays.

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

Hello.

From the HP site:

There could a problem in the pickup assembly area of the product. There are twoblack Mylar light shields approximately 3.5 inches long. They are located onboth sides of the pickup roller under the pickup roller rod. One or both ofthese black Mylar shields can be tucked under, or partially bent when removinga paper jam from the paper input tray slot.
Reposition the black Mylar light shields back into the proper position.
  1. Unplug the power cord from the product.
  2. Remove the paper and paper input tray.
  3. Slide hands, palms side up, into the paper input tray cavity until the fingertips reach the end of the cavity.
4. Bend fingers up to push theblack Mylar light shields back into place. The proper position of the blackMylar light shield will be flat.
5. Reconnect the power cord.
6. Print a self-test/configuration page to verify product is functioningcorrectly.
If still a problem, make sure that the tray, paper is locked in thecorrect position. Sometimes the spring in the tray can become worn out andloose. You can take that out and spread it out a little. Also, make sure thatthe tray bottom is free to move. Take out the paper and see if it goes up anddown correctly. If you don't hear the pickup roller moving or the motor runningyou may have a bad feed roller gear. There also, could be a problem with thepickup roller.

Hope this helps.

Windows XP The screen dims when the laptop is plugged in. Once the cord is removed the screen goes back to the normal brightness.


This is due to the power setting on your laptop.

You can right click on the battery (if its unplugged) or the power cable (if its plugged in) in the bottom right hand system tray by the clock.

Go to Power Settings.

You can change this under the power settings option.

Its most likely is not the switch. It is most likely the cord though. Due to the excess strain on the cord it has probably cut through the rubber coating on the wire and connected to the frame and grounded the hot lead. Fix the cord and you may have it handled.

Power issue


The power cord might be bent or screwed up. Or option two, the actual power connection in your laptop (i.e. the place where you plug in the cord to the laptop) could be broken on the inside.

Worse case scenario, it could be both.

If it is just the laptop cord, try another connection cord that will plug into your laptop. If it works, buy a universal adapter.

If it doesn't work, and you notice that when you plug it in to the laptop, it kind of wiggles around a bit or seems loose on the "inside" of the laptop ... you might need to take it in to a shop to have a new power connector sodered into place in your laptop.

Best of luck.
