Question about HP Pavilion ze4300 Notebook

1 Answer

HP Pavilion ZE4120s touchpad and front lights do not work. I opened the laptop to check the dc power jack, and after I have this problem. I had disconnected and reconnected the ribbon to the touchpad board. Originally I forgot to put in the hard drive before restarting, but then after the power up showed operating system not found I inserted the hard drive and the laptop came on. Could it be a bios problem, and if so how do i fix it.

What works and not. be clear.?
what OS? opr. sys.? (omg XP?)
that laptop is retired at HP, zero support now.
and finding one that works ? is like Woody Allen in "Sleeper "and the 2000 year old VW that runs....still.,(famous comedy)

just like cars old PCs can be fixed if LUCKY or find used parts.
finding used parts can be very hard some are impossible
or sit and park and pouch parts off fleabay for a year?

the HDD is always sold (and power packs and batteries)
as is W7 up. (2017 answer)
id bet MS does not sell your unstated OS
the oldest one is 2003 (says the service manual online)
so is XP, is my guess. Vista was 2006

XP is dead, its not supported now,
and is a virus magnet, see the UK Hospitals go down for XP?
last month, id never let XP into my home unless , internet cable was cut, to it.

ill answer for: IT RUNS THE OS OK< but.....
front lights, what lights.? please be clear on what?
touch pad dead. (ill work this)
The touch pad 13 years old can be just bad, its comon
the switches do not last for ever, infact short lived.
the HP site is dead now. for this PC.
so the drivers there for you XP are dead.
and microsoft updates are now dead for 3 years.

If i had this, or a friend did
id walk in to GOODWILL store
grab any Laptop with W7 COA sticker on the bottom and buy it
$20 is common price, why spend more, get a new lap to
heck even one with a real wide screen ?
then invest in it, fix IT .


if lucky, ?
go to Device manager, google that, XP device manager.
then see the key bad device.
internet connected to the WWW.
you click on that device, and click UPDATE it.
that is the only hope for IT.

MS cut the cord, Microsoft did on XP and VISTa and older.

I think you can see the black screen or the Bios screen even if you don't see anything further, or nothing at all? Cursor is another case, but once it tries to boot up, it should show something on the screen, like black screen with white text or something similar. If so, then I would suspect Windows Boot issue or some boot files might have been corrupted or damaged or deleted or missing.

I appreciate that you've already done the basics like reseating Hard disk and Ram. Now, you'll need a windows CD or a Recovery/repair disk, (since you didn't mention the O.S. name, i can't verify which Windows Recovery/Repair disk you should use, if it's windows vista, you have to use a Windows vista Recovery/Repair Disk). But here's another problem, since HP don't provide the Recovery disk (they only instruct to Order the Disk on Hp Official Website), you have to get one for yourself. Before you look for one, you have another option.

Once you press the power button to power up the Machine, keep tapping the F11 on the keyboard and wait, if you see anything on the screen, you have a chance (but not all problems) if you can proceed with the onscreen instructions and Restore the system to Earlier State, then proceed ahead and try with the System Restore Wizard.

You can also try with the Safe Mode, press the power button the Power-on the laptop and keep press F8 button on the keyboard, it'll direct you to the "Advanced Boot Options", if this is possible, then select "Safe Mode" from the options available (use the arrow keys and press enter to confirm and proceed). It'll show several white texts with black screen and will boot up after few minutes, if any message pops up to confirm your input, click "yes" or "Ok". Once it's successfully booted, uninstall some softwares or applications or drivers etc.. you had recently installed, again reboot the system into Normal mode, if Safe Mode is not possible, your last option (from your end) is to boot from a Windows CD and check if it can go well. These are all what you can do from your end, if these fail, you better call a tech or hp or take it to a local service center.

If you need further help, let me know.

Good luck.

Thanks for using FixYa.

Problem with HP 8510q laptop charging. Charging not working. Laptop working only that time when i have power in battery. Charging light not show. I try other charger but same problem. Is it inside some...


Inside? Yes. (If 'charger' is good)
Fuse?
No

Diagnostic flowchart:

A) AC adapter (Charger), has to be KNOWN to be good, before going on.
Used on a working laptop to see, or multimeter is used to check Voltage (DC)

The plug end that goes to the laptop, from the AC adapter, has a Center Hole, and a cylindrical outside metal shell.

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

The Positive (Red) probe lead of the multimeter goes to the Center Hole, and the Negative (Black) probe lead of the multimeter, goes to the cylindrical outside metal shell.

You should be reading 19 Volts DC.

Also have an assistant gently wiggle the cable FROM AC adapter TO laptop, and the power cable TO AC adapter.
If there is a fluctuation on the reading, there is a broken wire, or wires, in one of those cables.

B) Check the DC Power Jack.
This is the jack on the laptop (DC_IN) that the AC adapter plugs into.

Has a Center Pin, and an inner cylindrical metal shell.
Battery removed, use an eraser on the end of a No.2 pencil, and see if you can GENTLY wiggle the Center Pin around.

ANY perceptible movement of the CENTER PIN, means replacing the DC Power Jack,
(By the way, is it an 8510p, or 8510w?)

http://www.alldcjacks.com/en/ppj052-laptop-dc-power-jack.html

Any movement of the rest of the DC Power Jack (Body), means replacing it; or may just mean the solder joints are cracked, and can be re-soldered.

C) AC adapter and DC Power Jack checks out?
Problem may be with Power MOSFET's on the motherboard, and associated MLCC's.

(Multi-Layer Ceramic Capacitor, and they are SMD/SMT just like the Power MOSFET's.
Surface Mount Device/ Surface Mount Technology)

HP Pavilion dv8 not starting up


Ya know........Pavilion dv8 is a Series of Notebook PC's.

Encompasses a LOT of models in the series.

Have no idea of which LED in front you are referring to.

Do know;

1) Test the AC adapter (Charger) with an economical multimeter.
Average cost is $5 to $12.
Set to DC Voltage, and check the output voltage of the AC adapter.

As far as I can tell the DV8 series uses 18.5 to 19 Volts. (DC)
Use an AC adapter that is rated at 90 Watts, NOT 65 Watts; if using a replacement AC adapter.

The port on the laptop that the AC adapter plugs into is a DC Power Jack. (DC_IN)
The plug end on the power cable from the AC adapter, and plugs into the DC Power Jack, has a Center Hole, and an outside cylindrical metal shell.

The Center Hole is the Positive connection. This is where the Positive (Red) probe lead of the multimeter goes.
The outside cylindrical metal shell is the Negative connection. This is where the Negative (Black) probe lead of the multimeter touches.

Also have an assistant gently wiggle the power cord TO AC adapter; and power cable FROM AC adapter to laptop.
Intermittent reading indicates a broken wire, or wires.

DC Power Jack LED lights up? Means nothing to me. I want to know the FULL DC Voltage is getting TO the laptop, and there are no breaks in the wires of the power cable, or power cord of AC adapter.

THEN AC adapter checks out.

2) AC adapter checks out?
What condition is the DC Power Jack in?
Battery removed, use the eraser end of a No.2 pencil, and GENTLY see if you can wiggle the Center Pin around.

ANY perceptible movement of the Center Pin, means replacement of the DC Power Jack.
Fortunately for this series the DC Power Jack is connected to a cable with wires, and they end in a plug connector. Which plugs into the motherboard.
It is now a DC Power Harness.

HP calls it a Power Connector Cable.

http://www.amazon.com/PAVILION-Series-DC-IN-POWER-HARNESS/dp/B005WMWMMU

3) Next in line are the Power MOSFET's, in the power circuit section, on the motherboard.

!O_O!

MOSFET;

http://en.wikipedia.org/wiki/MOSFET

Power MOSFET;

http://en.wikipedia.org/wiki/Power_MOSFET

Should be on the motherboard, near where the Power Connector Cable plugs in.
Rectangular shaped with 8 'legs'. ('Legs' are J-Leads)

Believe one or more to be the problem.
Typed the rest above because it is a power flowchart, and when diagnosing always go through the steps.
Would s-uck to replace a motherboard, when the problem was an AC adapter, it's power cord, or the DC Power Harness.

This is more on the subject, by using the HP pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's; as examples,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Further this is to show the availability of the Fairchild Semiconductor - FDS6679 - Power MOSFET, and Alpha & Omega Semiconductor - AO4407 - Power MOSFET,

http://www.mouser.com/Search/Refine.aspx?Keyword=FDS6679

Scroll down.

http://www.mouser.com/Search/Refine.aspx?Keyword=AO4407

AO4407 has been phased out. Let's look at one of the cross-reference examples given,

http://www.mouser.com/ProductDetail/Diodes-Inc/DMP3020LSS-13/?qs=%2fha2pyFadujguNNSgppBRqXbOxXLwzGsZm9SWxz1EqWpzoSJOpHpWA%3d%3d

That is correct. $1.01 USD for a FDS6679, and 78 cents for a substitute AO4407.

http://www.youtube.com/watch?v=5uiroWBkdFY

http://www.youtube.com/watch?v=RjpNbuOrOuw

Also check the MLCC's (They are also SMD. Surface Mount Device)
Multi-Layer Ceramic Capacitor

Here are examples. Not correct values, Capacitance, (MicroFarad's), and Voltage,

http://www.mouser.com/Passive-Components/Capacitors/Ceramic-Capacitors/Multilayer-Ceramic-Capacitors-MLCC-SMD-SMT/_/N-b2cj?P=1z0wrjcZ1z0x565

Scroll down.

These will be close to the Power MOSFET's.
See if any are burned, or blistered.

Do you get any lights flashing at the charger? If you do it indicates that power is not completing the circuit and is being "spat back". This would indicate a damaged charging circuit or possibly a loose power jack socket, if it feels loose as you plug it in, you may need to change the DC socket

This sounds like you have a bad DC jack on your motherboard. This is one of the most common problems with laptops and can be caused by jarring the DC plug in or hitting it into something or simply from normal use. As a result the pins on the DC jack become loose and consequently do not provide a charge to the laptop and battery. Wiggling the plug can make the loose pins contact sometimes which would explain why it "sometimes" works when you unplug it and plug it back in. Of course if this is the case then your battery is mostly out of power and that is why it powers off after a couple seconds. This repair costs between $150-300 from a professional repair shop and I would not recommend trying it yourself unless you've had experience soldering DC jacks
Another issue could be the CPU fan/heat skin if this is failing or the CPU is overheating the laptop will power off.

Acer 5920g no power


Your DC Power Jack is bad, or the area of the motherboard where the DC power jack attaches to, is bad.

The DC Power Jack, is the small port where your AC adapter,(Charger), plugs into.
This is an example of an average DC Power Jack, for an HP Pavilion laptop, not installed in a laptop yet,
http://www.megaemarket.com/dc-power-jack-hp-pavilion-ze4200-zt117420011721182125.html
If you click on the photo it will enlarge.

The DC Power Jack in the photo is upside down, in relation to how it sits on your laptop's motherboard.
Those flat metal pins shown on top, go down through the motherboard, and are soldered on the other side.

1.Sometimes when the 'charger' plug is in the jack, and is bumped, it can crack the solder joints for the DC Power Jack's flat pins. This makes an intermittent contact. Eventually there is no contact at all.

2.Sometimes it's a bad design of the DC jack, and just from ordinary usage of the user plugging in the charger, and removing it, this can crack the solder joints.

3.Sometimes the small area of the motherboard where the DC power jack is mounted, can crack away from the main body of the motherboard.
To explain:
Crude example;
Envision a laptop's motherboard as having a 1 foot square shape. (It isn't. It's irregular shaped) Now on one side attach a 2 inch square. This 2 inch square, represents the area that the DC power jack is attached to. A 'Peninsula', if you will. There are circuit traces that go along a motherboard. Think of them as Very, flat, thin, strips of copper wire. These 'wires' become stretched, and break as the 'peninsula' cracks away from the main body of the motherboard.

Solution?
Have the DC Power Jack replaced, or the motherboard.
DC Power Jack cost? About $6 to $8 dollars.
Labor? $100 to $150.
The tech has to completely disassemble the laptop, to just the bare motherboard in hand. Then unsolder the DC power jack, resolder a new one in, and reassemble the laptop.
Motherboard cost? About $150 on up. Depends on where you obtain it. (Ebay?)
Labor? $100 to $200.
