HP pavilionA1217n fans stay on all the time never shut down


A few problems have arose from upgrading your Windows on HP machines. A HP laptop I used to own did the same thing to me when upgrading from Vista to 7. I would recommend looking for updates on HP's website. If you cannot find any, which I wasn't able to, I would use a program called Speedfan.

I hope that helps.

Where do we find the display lid switch for a HP Pavilion dv9715nr ? we replaced a damaged hinge on this laptop first and now we cannot get a display.


Let me guess. Damaged Left hinge?

HP had a recall for this problem, but the recall has lapsed as of May 31, 2009.

http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01611512

The Pavilion dv9000 series, also has a problem with the graphics chip overheating, and burning up.

Yes, I know. Just a regular ray of sunshine.

Graphics chip:
1) Chip is a slang term for I.C.
Integrated Circuit.

2) A graphics chip is a GPU. Graphics Processing Unit.

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

The HP Pavilion dv9000 series of Notebook PC's use Integrated Graphics, as commonly do a very large percentage of notebook PC's.
The GPU is mounted, { Soldered }, directly to the motherboard.

{Another term for Integrated Graphics is OnBoard Graphics.
On the motherBoard}

The GPU is an Nvidia GeForce 8600M GS, that uses the PCI Express technology.

The cooling system of this laptop (Notebook) has a poor cooling design for the GPU.

This causes the GPU to overheat, and burn up.
There is no just replacing the GPU. The fix is to replace the entire motherboard.

I would like to suggest a simple test to see if the GPU is bad first., before going on to replacing the Lid Switch Module.

Hopefully it is just the Lid Switch Module, or perhaps another simple problem I will detail. My thoughts at present, are that it is another small problem.

The test requires plugging in a VGA monitor to the back of the laptop, and seeing if the graphics are good.
(CRT monitor. Looks like a small television set)
Do you have access to a VGA monitor?

[ Bypassing the Lid Switch Module requires removing these components to access it;
1) Battery
2) Harddrive
3) Optical Drive
4) Switch Cover
5) Keyboard
6) Speaker Assembly
7) Display Assembly
8) Top Cover
9) Top Cover Trim ]

On the Left side of the laptop is a VGA port, to connect the VGA monitor to.
(Example of a VGA port:

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

Coming from the back of the laptop on the Left side, it is the second port.

VGA monitor plugged into laptop, power on.
Hold the fn key down, tap the F4 key.
Give the VGA monitor time to, 'Come to life'.

VGA monitor comes on?

GPU is good, time to go on with the diagnoses.

The Display Cable also routes through the Left Hinge.
This cable has the graphics signal cable, and the power cable for the LCD Display.

(The Microphone Cable also routes through the Left Hinge)

This cable is very small, and could have easily been pinched, which could cause breakage of the tiny copper wires, inside the insulation sheath of the cable.

If it is pinched, this MAY be visible by observing the plastic insulation of that cable. The cable does get slightly squished with normal usage, though.

With the Left Hinge being loose, and is hard to open anyway, the cable could have become stretched.

This would cause breakage of the tiny copper wires inside, and the outside damage to the insulation of the wire, may not be so readily apparent.

It could also be that the connector that plugs into the motherboard, has simply been pulled loose, or is not tightly plugged in, and is not making a good contact.

I will include the link to the Service Manual from HP Support, in an additional comment.

I do suggest you buy, and wear an inexpensive ESD wrist s-trap, and connect the alligator clip to a good ground source.
(Average cost is around $6)

Continuity test indicates the Display Cable is okay?

( The Display Cable disconnects from the motherboard, and from the Inverter, that is located in the Display Assembly.

The Inverter is what converts power for the LCD display screen, and also the Backlight Lamp.
The Inverter is a small circuit board, located behind the Display Bezel of the Display Assembly.

Cable disconnected from the motherboard, and from the Inverter, a continuity test of the Display Cable is done with a multimeter.

The multimeter is set to the 1K, or 10K scale.
An economical, but decent enough multimeter for this type of testing, can be purchased for around $12 to $15, from a local auto parts store )

Okay, now it's time to replace the Lid Switch Module.

I will give the link to HP Support, and the Service Manual for the Pavilion dv9500, dv9600, and dv9700 series, in an additional comment so you can disassemble the laptop to access the above.

Fan Exagerated Noise


The noisy fan is most likely caused by a worn/faulty bearing. This causes the fan to vibrate in the bearing and spin slower and therefore cause overheating CPU problems.
The CPU fan needs to be replaced.

Laptop pavilion 8310 no dispaly, getting beeps on start up


Remove laptop battery, and unplug AC power adapter for ten minutes, if this does not work there is either an hardware fault, or a system problem.

If the computer try to load Windows, then you get an error message,then you usually fix the problem reinstalling windows.

If the computer beeps and you get nothing on the screen, then it is usually an hardware fault.

Hp quick play stop working/all lights are on


Start > Control Panel > System and Maintenance > Device Manager > Sound, Video and Game Controllers. Right-click on Conexant High Definition SmartAudio HD2 and select "Update Driver Software." A window will pop up, select the option to download the drivers from the internet. Let it finish, it will prompt you to restart your computer. Restart either then or later when it's more convenient, and once you restart.

I had the exact same problem on the exact same notebook, I did decided to try this and it worked great. The only problem I'm having right now is that the volume controller didn't come up in the bottom right part of the screen like it usually does. I'm trying to find out how to get it back, but it really isn't important now that the volume control on the Quickplay keys works again.
