Don't know what manual you're referring to, but it isn't the HP 630, HP 631, HP 635, and HP 636 Service Manual; from HP Support,

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02834036/c02834036.pdf

Upper part of the laptop is the Top Cover.
Most of the time referred to as the Palm Rest Cover.

1) Remove the Keyboard
2) Remove the Optical Drive (DVD drive) (IF an option on your laptop)

3) Remove the Power Button Board and cable.
4) Remove the TouchPad Button Board and cable.

5) Remove the Top Cover

A) Close the computer
B) Turn the computer upside down, FRONT towards you.

Now pull this example of the Base Enclosure up in another window,

http://www.ebay.com/itm/646838-001-HP-635-BASE-ENCLOSURE-WITH-HDMI-/130659842589?pt=LH_DefaultDomain_0&hash=item1e6beefa1d

Put your mouse cursor in the middle of the photo, and use the Zoom In feature. (Put mouse cursor in middle, slowly move mouse around)

1) Looking at the FRONT edge, see the SIX screws that need to be removed?

2) See the ONE screw on the Left side, and Right side; that needs to be removed?

3) ONE screw to remove from EACH corner on the REAR side.

4) Battery Compartment / Rear side;
There are FOUR screws to remove that are along the Rear side of the Battery Compartment, and DOWN in the Battery Compartment.

4) Battery Compartment / Front side;
There are THREE screws to remove that are along the Front side of the Battery Compartment, and DOWN in the Battery Compartment.

5) DOWN in the Harddrive Bay Compartment there are FOUR screws to remove.
TWO on the Right side, TWO on the Left side.

IF I count correctly there are 21 screws to remove from the Bottom.
(I ran out of toes and fingers)

6) Turn the computer back over to it's normal position.
Open the laptop.

Grab the Jaws of Life and....................

Just wanted to see if you were following along.............

The rectangular area under where the Keyboard was, and has multi ventilation holes in it, is the Static Shield.

To the Upper Left corner is the Power Button Board cable, that needs to be disconnected.

To the Middle/Front is the TouchPad Button Board cable that needs to be disconnected.

Looking to the upper right there is a hole, and a screw that needs to be removed.

More detail;

Looking at the ventilation holes going across as rows.
Come down to the 3rd and 4th row of ventilation holes.
Come OVER from the Right side SIX ventilation holes.

That hole, that screw; needs to be removed.

IF it still uses this style of fastening;

The Top Cover has TABS going around the exterior perimeter, of the inside edges.

These Tabs snap into matching LATCHES in the Base Enclosure.
(Bottom Cover)

I use a thick stiff guitar pick to start popping the covers loose from each other. (Top Cover from Base Enclosure)

I would ease the pick in the parting line of Top Cover, to Base Enclosure, towards the Rear/Right side.

You just want to ease the pick in, so you can start to get your fingertips in.
Can't get the pick in? Move over. You are at a Tab/Latch.

Once you get the Top Cover to start to separate, use your fingertips, and move along towards the Front.
Go around the Front popping the Tabs/Latches loose.

By the time you get halfway around the Left side, the Top Cover may pop off.
I state MAY, because I have had some I had to fight all the way.
(Pop EVERY Tab/Latch loose)

I hope you are wearing an ESD wrist strap, and have it's alligator clip attached to a good ground source.

IF not, open the backdoor, and throw your laptop out.
(Unless you just want to use it as a doorstop)

Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
An ESD wrist strap, and connected to a good ground source, will keep your laptop safe from Static. (From you)

The CPU (Processor) is the most susceptible hardware component to Static shock.

You know the above? Good. I also posted for people who read this solution in the future.

Out of curiosity what CPU are you going to install?

[Plus; DO NOT post your email address on FixYa!]

For additional questions please post in a Comment.
Regards,
joecoolvette

[Memory Module/Wireless Module Compartment Panel is removed, then there is a screw to remove down in the compartment, that is for the DVD drive.
Remove screw to slide DVD drive out of laptop.

Can't get a hold of DVD drive? Tap the tray release button, ease the tray all the way out. Gently pull on tray until DVD drive comes out enough, that you can grab it ]

    I think you are doing a Commendable job with the English language, sir. I apologize that English is all that I am fluent in. However I cannot understand all of your last statements. Let's start with the first one, "I'm installing, AMD Phenom II Mobile N-660 3.0GHz Dual-Core, to cover my older 1.65GHz amd e-450." http://h10010.www1.hp.com/wwpc/us/en/sm/... Yep. That will work. Second statement, "And I didnt actually found the part as what do i do after removing keyboard, i have removd, ODD, HDD, WLAN, and disconnected all cables." Unclear here. Ah, DING! I FORGOT to include the SERVICE MANUAL. Sorry about that. Kinda' hectic around here,http://h20000.www2.hp.com/bizsupport/Tec... This HP Support page should open for you, with the bold black subheading at the Top; Service and maintenance information. Click on the file name under it; HP 630, HP 631, HP 635, and HP 636 Notebook PC - Maintenance and Service Guide. That is the Service Manual. The last statement I am unclear of, "And no i also other problem, I added 2GB more RAM to my laptop, but i still have same amount RAM for use."

    With part "And I didnt actually found the part as what do i do after removing keyboard, i have removd, ODD, HDD, WLAN, and disconnected all cables." I was referencing to what joecoolvette already posted for this topic.

    Before I go further wHeRe are my manners? Thank you for the rating! Moving on..........Ignore if you are aware. The Service Manual is in PDF file form. The computer you're using has Adobe Reader on it, which uses PDF files. After you click on the file name, (HP 630, HP 631, HP 635,....), it may take up tpo 30 seconds before the first page comes up. After the PDF file (Service Manual) comes up, go to the top/left corner, and click on the icon, Toggle Slider. It nows spreads into two icons, Show Thumbnails, and Show Document Outline. If you click on the Show Document Outline icon; the Bookmarks menu will appear. A) Illustrated Parts Catalog - Page 25. (PDF file page number at Top) Here you can see an exploded drawing of the laptop, plus parts numbers for the various components, and Identification of the various components. Page 64 - Top Cover, deals with replacing it. Shows and tells you how to remove it. Has the component removal procedures in an order, and highlighted in blue. Click on each one, one at a time, and in order. When the component has been removed, go back to Page 64. Remove the next component in the list. Then go back to Page 64, and so on.

    You have the ODD, HDD, WLAN Module, and Wireless Antenna cables removed. I also assume by, "........and disconnected all cables.", you are also referring to the TouchPad cable, and Power Button Board cable. Have you removed ALL screws from the bottom? Pages 64, and 65 show them. IN the Static Shield, where the Keyboard was; did you remove that single Philips head screw? Page 66. As I previously stated, the Top Cover may have TABS going around the exterior perimeter of it's inside edges. These Tabs SNAP into matching LATCHES on the Base Enclosure. (Bottom Cover) I'll show you some information about popping that style of covers apart. (I use a thick stiff guitar pick to start. Slide in-between the parting line, where the Top Cover meets the Bottom Cover. Can't get in? Move over. You are at a Tab/Latch. Now I use a Spudger Tool. They're about $3 USD. One example,http://www.ifixit.com/Tools/Spudger/IF14...

Hdd driver for WD 3200BVT-80JJ5TO DATE. 6 OKT 2011. And how it happen was when I was reinstalling windows I deleted the driver for hdd and now I am really in trouble..... Please answer A.S.A.P. Thank

Paul,
The driver for the HDD is actually built into the HDD. Windows 7 contains a driver to communicate with the drive. If you have a backed up copy of your operating system (created by you on DVD's or CD's when you purchased the machine) then you have all you need to do a complete erasing of the hard disk and restoring it to the way it was when you purchased it (all your added data and programs will be lost).

Performing a system restore:

HP Recovery Manager software allows you to repair or restore the computer to its original factory state. HP Recovery Manager works from recovery discs, a recovery flash drive, or from a dedicated
recovery partition (select models only) on the hard drive. NOTE: A system restore needs to be performed if the computer hard drive has failed or if all attempts to correct any functional computer issues fail. A system restore should be used as a final attempt to correct computer issues.
Note the following when performing a system restore:

You can restore only the system that you have previously backed up. HP recommends that you use Recovery Manager to create either a set of recovery discs or a recovery flash drive as soon as you set up the computer.

Windows has its own built-in repair features, such as System Restore. If you have not already tried these features, try them before using HP Recovery Manager.

HP Recovery Manager restores only software that was preinstalled at the factory. Software not provided with this computer must be downloaded from the manufacturer's Web site or reinstalled
from the disc provided by the manufacturer.

Restoring using the dedicated recovery partition (select models only)

When using the dedicated recovery partition, there is an option to back up pictures, music and other audio, videos and movies, recorded TV shows, documents, spreadsheets and presentations, e-mails,
Internet favorites and settings during this process.

To restore the computer from the recovery partition, follow these steps:

1. Access HP Recovery Manager in either of the following ways:

Select Start > All Programs > HP > HP Recovery Manager > HP Recovery Manager.

- or -

Turn on or restart the computer, and then press esc while the "Press the ESC key for Startup Menu" message is displayed at the bottom of the screen. Then, press f11 while the "F11 (System Recovery)" message is displayed on the screen.

2. Click System Recovery in the HP Recovery Manager window.

3. Follow the on-screen instructions.

Restoring using the restore media

1. If possible, back up all personal files.

2. Insert the first recovery disc into the optical drive on your computer or an optional external optical drive, and then restart the computer.
- or -
Insert the recovery flash drive into a USB port on your computer, and then restart the computer.
NOTE: If the computer does not automatically restart in the HP Recovery Manager, the computer boot order needs to be changed.

3. Press f9 at system bootup.

4. Select the optical drive or the flash drive.

5. Follow the on-screen instructions.

Hope this helps you out.

MY LEFT CLICK ON KEYBOARD SCREEN MOUSE BOTTOM LEFT ON HP ELITEBOOK8440P DOESNT WORK HOW CAN I FIX

Please go to the HP website and download the free repair manual for this computer. The keyboard must be replaced. Usually it cannot be done by the average owner because of knowledge and tool absence. If you have tools and the manual is understandable to you give it a try. I would watch ebay for a parts only computer at an affordable price, ask the seller if the keyboard is OK), if so, buy it and remove the keyboard. The knowledge you would gain might qualify you to join Fixya for similarly assisting others with this problem. My specialty is the hinges on HP laptops which can become unworkably stiff and break off after being forced. Replacing these requires an almost complete disassembly of that specific laptop, a programmed sequence that must be followed step by step ergo the need for the repair manual.

Nc6000 doesn't boot unless I push on the keyboard

Your graphics chip has a cooler which tends to separate from the motherboard causing a failure on bootup. This can be fixed by adding a spacer to the cooler then reattaching the cooler with the 2 screws which hold it down. This chip and cooler are located directly beneath the keyboard which is why pushing down on the keyboard causes the laptop to work for awhile. Releasing the keyboard is pretty easy since the screws are identified on the underside of the laptop. Remember to add thermal paste when re-applying the spacer and cooler.
