HP dv4000 Static discharge shuts down my laptop

Laptop - HP dv4000 (dv4040us)

Problem - If I discharge static shock to the side of my laptop it will shut the laptop down. This happens when I stand up and if my jeans touch the side of the laptop and static discharges and a spark comes off the laptop will shut right down.. I am sure this is not good for the laptop..

I do work in the IT Department but I do not work one laptops so I am not sure what to look for when I take the laptop apart...

Honestly, it sounds as if the laptop has some sort of power issues as it shouldn't be creating static. If you are going to take it apart yourself, look for damage to all connectors, especially around the power connection as damage here could lead to greater problems down the road. Otherwise, I would recommend taking it to an Authorized HP Repair center.

I have recently replaced my hp 4530s screen now computer wont start

A) Which method did you use?
The one straight out of the Service Manual, or this style?

If the style above, suggest you do not have the Video Cable plugged in tight, to the the back of the LCD screen; and/or webcam cable.

If the style straight out of the HP Service Manual,
I can go down a long list;

1) Didn't follow Anti-Static Procedures, and Static shocked out the delicate hardware components for the laptop.

Laptop is junk now.

2) Didn't get the Power Button Board, Flat Flex Cable (FFC);

Inserted back into the correct direction. You may have it flipped upside down.
You may not have the FFC slid in all the way.
You may have forgotten to even connect it.

Fortunately a fairly common thing, so I will not deduct you two computer geek points for that. (lol!)

I'm going to stop, and wait for you to tell me which method you used, and also if you FOLLOWED Anti-Static Procedures.

Post back in a Comment.

What causes my pc to shock nd wats d solution

If you are getting shocked every time you touch your laptop then its because your building of static electricity from your environment. It's just physics and touching anything metal, like screws on the laptop, will discharge it.

How to open up to chick the hard drive

Before you start, be aware that minute traces of static electricity can destroy a hard drive. If possible, wear an anti-static wrist or foot strap; at the very least, do not work on a carpeted floor, bed, or while wearing static-producing clothing (like fleece). Work on a non-conductive (wood, glass) table grounded to a non-conductive floor (wood, linoleum, tile). Wear latex or anti-static gloves and turn off fans and close windows to avoid dust damage.
1. If you haven't already, back up your data on an external drive. 2. Shut down the computer and unplug the power cord from the computer. Remove the battery. 3. Close the laptop and set it screen-side down on an even surface, with the hinges facing away from you. It should look like this:
4. The component labeled "7" in the above picture is your hard drive. With a small Phillips head screwdriver, carefully remove the screws on this outer casing only. Set them aside and remove the hard drive cover. 5. Your hard drive will be screwed in by one to four screws, depending on assembly. Gently unscrew these, being careful not to apply too much pressure to the very delicate top and bottom of the drive. Handle by the sides only. 6.There are connecting pins on one side of the hard drive. Identify these and gently pull the hard drive out from this side, not forcing if there's any resistance. 7. Depending on your problem, you may need to remove the silver enclosure to the hard drive. With the appropriate Phillips head screwdriver, unscrew the screws and set them aside, carefully sliding the enclosure off of the hard drive. At this point, your hard drive is extremely susceptible to shock, electric shock, dust, and simple trauma. Be careful.

How to change the screen on a hp pavilion dv4-1465dx laptop

A) Remove all electrical sources; The AC adapter (Charger) and the Battery.

B) Obtain a multi-compartment container for the screws you will remove. There are screws which look alike, but aren't. You won't realize the mistake until you have the screw in halfway, it is then stuck, and CAN'T remove it. Gives you a warm fuzzy feeling all over.

You can use a clean egg carton in a pinch. Label each egg holder for what area the various screws came out of.

C) Suggest you buy, and wear an ESD wrist strap. (Electro Static Discharge) They cost from $3 to $8. The area you are going into is relatively safe from static shock, as there are no hardware components that are nearby, and prone to Static shock, BUT, it never hurts to be safe.

Static WILL fry out (Short Circuit) the hardware components of a computer, (Laptop or Desktop)
You probably won't see it, or feel it.

Connect the alligator clip to a good ground source. I connect to the metal frame of an empty desktop computer case.

D) I don't find a Service and Maintenance Guide on HP Support, but the information from this link should do very nicely,


It's a dv5 series, but you'[ll find it crosses over to your dv4 series quite well.

Steps on taking the keyboard off the laptop

1) The Pavilion dv9000 you're referring to is one of the Pavilion dv9000 series. The specific model number is on the bottom of the laptop, in a white Service Tag. P/N is Product Number. HP's model numbering system.

Just posted for future edification should you have problems with another laptop. All Model Numbers will be on the bottom of the laptop, HP or no.

2) I would like to start with a link to the Service Manual, for your Pavilion dv9000 series laptop.

On this page scroll down to - HP Pavilion dv9000 Notebook PC - Maintenance and Service Guide, and left-click on it.
This is a PDF file.
May take up to 30 seconds before you see the first page. Additional time to fully fully download.
(Took 18 seconds to see the first page, and no additional download time, for me just now. Medium speed DSL)

Agree. Your diagnoses leads me to believe the Display Cable (Wire) has a break in it.
Switch Cover removed, (Plastic strip on top of the Keyboard, and below the LCD screen, I referred to before), the Display Cable is the cable (Wire) to the far Left. (Long connector) The cable next to it on the right, is the Microphone cable.
(Short connector)

(Next cable going to the right under is under the Keyboard, {But not connected to the Keyboard}, is the Camera cable. The long cable coming from under the Keyboard, and going off to the far right top corner, is the Wireless Antenna cable.

Also check the Backlight cable. This is the cable on the right side of the LCD screen, and goes to the Inverter mounted inside, at the bottom of the LCD Top Panel Cover. (The Lid, in otherwords) When you state your display does not come up, I assume you have checked the LCD screen with a flashlight, to see if the problem is just the Backlight Bulb is not working. An LCD screen does not provide enough light by itself. Needs that type of Florescent light bulb, (CCFL. Cold Cathode Florescent Lamp), to fully illuminate the LCD screen.

If the Backlight Bulb cable has a break in it, you won't be able to see the display.

Good news?

Not much I'm afraid, unless you're really good at soldering, or HP does indeed still sell that display cable, if it's bad. It's a multi-wire cable.

The Display cable also goes down through the laptop, and connects to the motherboard. You have to almost completely disassemble the laptop, to get to the display cable's connection on the motherboard.

Laptops are disassembled from the Top going Down. You do not just remove the Bottom Cover.

Things I would like to suggest.
FOLLOW Anti-Static Precautions, before you go any further into your laptop. (If you aren't following them already)

Anti-Static Precautions:
Your body carries Static electricity. Static WILL fry out Short Circuit) the delicate hardware components, inside a computer.

Relieve your body of Static BEFORE going deeper into that laptop.

With a desktop computer you just unplug it from power, and Touch the metal frame of the open computer case. The frame is made of steel.

The metal used inside a laptop is non-Ferrous. No Iron. Makes it so that the metal is non-magnetic. Also will not work for relieving your body of Static.

You can touch a doorknob to relieve your body of Static. The door better be within a one-step distance from where you're working. The movement of your feet, the rustling of your clothes, are 2 things that create Static.

Better method is to buy, and wear an ESD wrist strap, and connect the alligator clip to the metal frame of an open desktop computer case, unplugged from power.
[Electro Static Discharge. They run about 6 bucks)

In the PDF Service Manual ('Guide'), in the Bookmarks on the left side, scroll down to the section heading, Removal and Replacement Procedures, and click on the + sign to the left.

Now click on - 5.24 System Board. (Or Page 191 for the PDF page number)

Takes you through completely disassembling your laptop.

Check the Display Cable with a cheap multimeter set to Ohms. You are performing a Continuity Check of that cable. Wiggle the cable when checking with the multimeter.

My hp laptop is not turning on what should i do, it happened when i tried to insert the memory card after which my hp laptop turned off


Hopefully, you did not try to put the memory card in while the pc was on and you ground yourself to the pc first. You would be amaze how quick it is to short your motherboard with static shock. Try taking the memory card out and power on your pc. If it power on, you may need to use a different memory card or make sure it is completely seated in the slot. If the pc don't power on, you may have shorted your board and it wil need to be replaced.

Good Luck

Static shock possibly fry my soundcard?

Static shock can fry your sound card from electro static discharge and it can also fry other PC components try another set of headphones in the pack of the PC. Or another pair of speakers rather than using your monitor and see what happens.
