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!

What to do when the power is not stable


I'm not sure if you mean (1) your utility power supply is not stable or (2) your router power supply is not stable.
If (1) you can purchase an uninterruptible power supply (UPS). A line interactive unit will probably best.
If (2) the problem may be a loose or damaged power cord. Try jiggling the power cord at various points. Breaks usually occur near plugs but can occur anywhere, especially if you have biting animals around. Sometimes power plug pins can be bent slightly to improve connections. Make sure the power cord is unplugged before trying this!

Lexmark E450dn will not power on, power cord is working


This issue may be due to one of the following:

  • An incorrectly set power switch.
  • An improperly functioning power outlet, surge protector, or power supply backup.
  • A poorly connected power or data cable.
  • A defect with a third-party (i.e. non-Lexmark) option such as a memory card.
  • An incorrectly connected or malfunctioning optional paper tray.
  • A malfunctioning printer component.
Please try the following steps:

Step Action 1 Make sure the power switch is in the "on" position. If it is, power off the printer. 2 If your printer's power cord is plugged into a surge protector or uninterruptible power supply (UPS), unplug it and connect it directly to a grounded wall outlet. Some of these devices can interfere with consistent electrical flow and cause the printer to fail to power up properly. 3 Disconnect the power cord from the back of the machine and then reconnect it. Make sure the power cord is plugged in all the way. 4 Disconnect any data cables (parallel, USB, Ethernet) from the rear of the printer. Any defect in a data cable may cause an electrical short circuit that could cause a loss of power to the printer. 5 Turn the printer on, this time with only the power cord connected and plugged directly into a grounded wall outlet. 6 If the printer still fails to power up, power off the printer once more. Verify that the outlet is working properly by connecting another device to it to see if it receives power. You can also try plugging the printer into a different grounded outlet. 7 If possible, try another printer power cord. 8
Verify that the printer is the correct voltage type for the environment in which it is being used. A 110V (low-voltage) printer will not work properly in a 220V (high-voltage) environment, and vice versa.

  • NOTE: Look at the rear of the printer and locate the electrical specifications sticker. Verify that the voltage rating on the sticker is the correct voltage for your printing environment (i.e. 110V or 220V).
9
Remove any third-party (i.e. non-Lexmark) options, such as memory cards, as they may interfere with proper printer functioning. Also remove any paper-handling options such as an optional second paper tray. 10
Attempt to power on the printer once more with all options removed, having verified that other devices work from that power outlet.
If there is still no power, the printer may require service to fix the issue. Please contact Lexmark Technical Support or a local service provider.

Schmetic for roper dryer - need drawing showing set up for installation '


Are you trying to connect your power cord to back ? Dryers are all about the same. But all new dryers are designed for 4 wire plugs .. If you have a three wire plug or cord the white connection and the green ground connection go togather on the center ground wire to your 3 wire plug.

Two speakers hum noise


Very doubtful that hum issue is ground potential difference from multiple power outlets as power cord is not grounding type (it is transformer isolated). I do agree that it is good practice to connect all audio equipment to common power strip though, especially with pro sound. Check the audio cords connecting your speakers to the coumputer sound card: 1) Make sure they are connected to the correct jacks and plugged in all the way, 2) wipe the connectors off with a clean paper towel wetted with a smidge of WD-40, 3) replace cords if all else fails. I have also seen solder joints fail on the power supply capacitors (due to vibration) causing hum -- but leave this repair to an electronics technician due to dangerous voltages.

My window unit fell out of the window and hung by the power cord that was still plugged into the wall. I was able to grab the cord and pull it back up. I reattached the power cord and now every time i turn...


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.

I drove through some high water and flooded my engine. Trying to let the car dry out and be able to get it running without taking it to a shop. Any suggestions on what to do?


Depending on how much water you got into the engine you could have irreversible internal component damage. I would start by removing all of the spark plugs and then try to crank the motor. If you are hearing knocking noises at this point it is barely worth putting the spark plugs back in the motor as it is blown. If you hear no knocking while clearing the water out of the cylinders reinstall the spark plugs and try to start it momentarily (DO NOT LET IT STAY RUNNING). If you still have no engine noise I would proceed to a oil change. At any point if it is knocking or refusing to turn over normally with the plugs out you can count on a bent connecting rod or bent crankshaft. Hope this was of help to you.

Hello- carriage jam


I was just getting ready to pull the plug on this printer of mine, and order a new one, when I happened on a solution that worked...

Unplug the unit.
Open the top.
Move the carriage to the left.
CLEAN the black plastic tray that the ink cartridge "parks" over - it seems to collect gunky ink that impedes the movement of the cartridge... also clean the "rail" hehind it. I used a Windex knock-off -- and Q-Tips, somebody else said they used alcohol.

Seems to have done the trick for me. I wasted so much time downloading drivers thinking that it was a hardware problem :-(

HELP ME WITH MY 4 PRONG CORD


first: the cord: The green is chassis ground. The white is neutral (a ground from the power company) .. red and black are 'hot'. Never plug this in until the installation is complete.

On the dryer, these are labeled as well. Install a strain relief clamp and nut on the wire setting up to go through the box knockout... nut on the inside of the box...you'll tighten it after you make up the connections. Match up the blacks and reds. The others may be installed so the neutral and the ground are both connected to the same point if not separately labeled. If one of the points just goes to the chassis (there may be what looks like an arrow made up of 4 horizontal lines pointing down on the label)...hook the green there. Install the white to the other terminal...again it is called neutral. Make all connections tight. If the motor works when you start the timer...you're in business.
