Missing key drivers

Go to the manufacturers site first (I assume it's an Acer) to see if they have the dirvers you need. I'm unsure if you mean you the 'key drivers' as in the main drivers for the computer, or 'key' drivers for the keyboard (you don't need any drivers for the keyboard unless its an external gaming keyboard, in which the manuafacturer will have the drivers on their site, and on the included CD if you still have it). If you need all the drivers try these softwares if you cannot find them from the manufacturer:
You can also try these special driver scanners to see if drivers you need are available:
Driver Genius, Driver Magician, Driver Scanner, Driver Finder and Driver Checker. These will scan your computer and tell you which ones you need and allow you to download them if they are available.

Replacing fuse in ze4220

There is no fuse.

On this page click right on the file name -

HP Pavilion and Compaq Presario Notebook PC - Service Manual
(6.24MB in size. {6.24 MegaByte )

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.

After you click on the file name above, it may take Up To 30 seconds, before the first page comes up.
Wanted you to be aware so you won't think it isn't downloading.

This is a Temporary download. Just so you can view it now. There is a way to save it to your computer, however.

This way you can burn a copy to disk/flashdrive, and have it for safekeeping.
You can also, after checking out that it's a good copy, delete it from the computer you downloaded it on, and save harddrive space.

User-replaceable is another word for FRU.
Field Replaceable Unit.

A unit (Part) that a tech can replace in the field. If it cannot be replaced in the field, the laptop is sent to an HP repair depot.

Where it states - Authorized Service Providers Only.
YOU, can also replace these parts.

1) Remove ALL power before working on a laptop. Remove the AC adapter (Charger), and Battery

2) FOLLOW Anti-Static Precautions.
USE an ESD wrist strap, and connect it's alligator clip to a good ground source.
(Electro Static Discharge. Average cost is around $3 to $6 )

3) Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s came out of.

SOME screws look VERY similar to other screws. DO NOT mix them up.

[One case in point. Put a screw that looks the right size, but is the wrong thread, in a hole. May go halfway in.

WILL NOT remove unless it breaks that section of motherboard OUT.
Will Not go in further ]

No power to laptop?

1) Check the output voltage of the AC adapter. (Charger)

The output cable's plug from the 'charger', has a Center Hole, and an outside cylindrical metal shell.

The center hole is the Positive connection.
The outside cylindrical metal shell is the Negative connection.

Use a multimeter set to DC Voltage, and check for 18.5 Volts. (DC)

[An economical, but decent enough for this test, multimeter, can be purchased for as little as $8 to $12.

Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.

The Function Knob is set to DC Voltage. If just a symbol shown, the symbol is a dotted line over a solid line.
If more than one scale set it to the 0 - 50 volt scale.

Red probe lead is the Positive lead.
Black probe lead is the Negative lead.

Have an assistant gently wiggle the power cord, FROM the surge protector to the AC adapter. Also wiggle the cable from the AC adapter TO the laptop.
Look for an intermittent reading on the multimeter. If so it indicates a break in the wires.

HAS to be 18 to 19 Volts. (DC)
CANNOT have any breaks in the wires.

AC adapter checks out go on to the DC Power Jack.
May be labeled on laptop body as DC_IN
This is where the AC adapter plugs into the laptop.

Enlarge the photo, (In blue; Actual photo - Click to enlarge )

The DC Power Jack is shown upside down, in relation to how it actually sits on the motherboard.
The 3 flat bladed pins you see sticking up, go down through the motherboard, and are soldered to the motherboard.

[ Center flat bladed pin is for the Center Pin, or Positive connection.
The two outer flat bladed pins are for the inside cylindrical metal shell.
The Negative connection ]

The solder connections made are Solder Joints.
One, or more solder joints may be cracked.

This would make a poor connection of AC adapter to laptop.
Resulting in the Battery not charging, and the laptop not receiving power to run on.

ALL power removed use a small tool, and see if you can gently move the Center Pin around, or the rest of the DC Power Jack.
ANY perceptible movement indicates a problem.

Disassembly is required down to the motherboard in your hand, to see what the problem is.

May just need to resolder the cracked solder joints.
MAY need to replace the DC Power Jack.
MAY be a cracked/broken motherboard. In this case replace the motherboard may be the only alternative.

DC Power Jack checks out it's on to the Power On switch, located under the Power On button.

It may be bad.
The Power On switch is mounted on a Power Board.
HP name = Switchboard PCA

Note that the Switchboard PCA has a cable from it, that plugs into the motherboard.
The Switchboard PCA cable's connector, has the socket holes.
The matching connector on the motherboard has the contact pins.
TWO of them.

Carefully use a small flat tipped screwdriver, and temporarily touch against the two pins. (No more than a 2 second contact )

Laptop comes on you need a Switchboard PCA.
HP part number - 317445-001 (F5761-60905)

If you have gotten this far, and the laptop will not power up, you have Real problems.

There is a chipset that controls power in the laptop.
Power Correcting chipset.

Checks whether the laptop;

1) Runs off of just the Battery.
2) Runs off of just the AC adapter
3) Sees if the Battery needs a trickle charge, or a full charge.

It is a type of Power MOSFET,

Here are two examples that are used quite a lot,



The chip usually looks burned when it is bad. Motherboard replacement is easier.

[ By the way. ZE4200 is the Model Series.
It ISN'T THE Model Number.

HP = Manufacturer
Pavilion = Model Line
ze4200 = Model Series

The Model Number for HP = Product Number
The product number to the right of - P/N, in the white Service Tag, on the bottom of the HP laptop ]

I have an HP Pavilion dv9812us and today when I went to turn it on...nothing. Lights on the quick play flash and thats it! Took the battery out and disconnected the power supply...did the hard reset...held...

The issue might caused due to two reason, Loose memory module (RAM) or the issue with nvidia graphics chip.

Here is the weblink to remove and reseat the loose memory module.

If the issue persist then you need to replace the system board for graphics issue.

PC board details: Part Number : 459567-001

Systemboard (motherboard) - For full-featured (UMA) PCA, supports AMD Athlon processor

HP Pavilion dv2500 - FTB

The troubleshooting you have done seems to be fine. It does not seem to be a problem with the power supply,cord or battery.Did you try a hard reset. If there is a reset button on the bottom of your laptop, you might want to try pressing that with laptop plugged in, not plugged in, with battery, without battery and different combinations thereof.
If this does not work or you don't have a reset button read on.

Before assuming it's the motherboard, there is one other possibility. There is a part called a PCA switch. It is possible this switch has gone bad or a plug might have come loose.

If you are comfortable with doing your own work, you can obtain a repair manual for your laptop online. Within this manual, it should explain what is involved in replacing this part. It is really not too complicated.

It does not sound like a hard drive problem simply because it doesn't seem to be getting power to any other part of the laptop.

You can try these steps.

I have an HP 5000 Series laptop. Just installed a new cd/dvd still didn't recognize new drive.

Firstly, try reconnectnig it and make sure you push it all the way in. Then try this:

1. Got to Run on the startmenu. And type regedit.
2. Open HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass.
3. Go to the first folder that starts with {4D36...
4. Delete UpperFilter and LowerFilter.
5. Reboot the unit.

If it still doesnt work after this try a full system recovery. If that doesnt fix the issue you might need a new CD-PCA board or mainboard. But it can also be a DOA(dead on arival) DVD-ROM.
