there is no limit on max. hdd.
sorry, only the format limits that.

why spend hard cash on old IRON./ its now retired, no support
why not go to Goodwill and find a W7 or newer LT.
for like $20 and have some value in your hands.
old dmm sticks are hard to find, that are good.
many of the old RAM are not made now. sorry

if only one slot is found then there is only one slot
the books are obsolete and very hard to find
i tried to buy parts for this and found almost none.
why do this.?>?? sorry but why?

page 5-10 in your book shows 1 stick
why think there is more>? this old.

what does RESET mean. tell the helper that first.
my guess is you mean BOOT?

first take out the relic battery (i bet its old and shorted)
does, BIOS work now, hit the BIOS key? yes/no
does it boot to the hDD, now?

To installed W7, Who's, Microsofts or HPs' latter works other dont.
using CD driver to install w7, that it?
does the CD boot and run and ask all the normal questions?
it takes a good HDD to installed W7.
for a fact.

I test the PC with a Linux live disk or Windows PE live disk
first to see if all is good, then run HDD tests from there.
using HDD test software, (free from hundreds of sources) ask

then install w7, when sure.
battery is out.
power pack ok.
and HDD ok.
only then can it work. (if luckly , )

Check that brightness is not turned right down, you do this using the function keys, Fn and one of the Fkeys the top line of your keyboard. Another thing to check is that external monitor has not been aactivated. This can be corrected by using the function keys as well.

Could be a bad;
1) AC adapter (Charger),
Or
2) DC Power Jack, (Jack that the AC adapter plugs into on the laptop),
Or
3) Power On switch, (Power Button Board),
Or
4) Display Lid Switch Module,
Or
5) Power MOSFETs on the motherboard,
Or
6) Ceramic Capacitors on the motherboard.

1) AC adapter:
General example,

http://www.amazon.com/Original-HP-65W-Adapter-Pavilion/dp/B002QCUIZC/ref=sr_1_6?ie=UTF8&qid=1350152535&sr=8-6&keywords=ac+adapter+hp+dv2000

The plug end that plugs into the laptop has a Center Hole, and a cylindrical metal outside shell.
The center hole is the Positive connection.
The cylindrical metal shell on the outside is the Negative connection.

Multimeter function knob set to DC Voltage, the Positive (Red) probe lead goes to the Center Hole.
The Negative (Black) probe lead touches the cylindrical metal shell.

[An inexpensive multimeter can be purchased for as little as $5 to $12. Available in a multitude of stores. An auto parts store is but one example, or look on the checkout aisle racks of major discount stores.
If just a symbol, the symbol for DC Voltage is a dotted line over a solid line. More expensive multimeters have an auto detect feature, that sense when the multimeter is connected to AC voltage, or DC voltage )

You should read 18.5 Volts (DC)

While testing have an assistant gently wiggle the cable from AC adapter to laptop, and the power cord to the AC adapter. A fluctuation of the reading indicates there are broken wires.

AC adapter checks out OK?
Go to the DC Power Jack.

The DC Power Jack on the laptop may have DC_IN next to it.
It has a Center Pin, and surrounding metal shell.
Battery REMOVED, use a No.2 pencil, and see with the easer if you can move the center pin.

If so the jack needs to be replaced.

The DC Power Jack for this model series is attached to wires, that end in a small white plug.
The small white plug plugs into the motherboard.
Easier to replace, than models that have the DC Power jack soldered directly, to the motherboard.
It's a DC Power Harness, and HP labels it a Power Connector Cable.

HP 430462-001 for models that have a UMA motherboard.
HP 430461-001 for models using an Intel processor.

DC Power Jack checks out OK?
Power On switch.

In the list click on -
HP Pavilion dv2000 Notebook PC Maintenance and Service Guide

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 above file name, it may take up to 30 seconds before the first page comes up.

The PDF reader page numbers, and the actual manual page numbers, do not match. When I refer to a page it is the PDF file page.
Go to Page 141 - Switch Cover
Pages 142 and 144 have more details on the Power Button Board.
(Power Button Board is HP part number 417084-001)

How to test?
Multimeter set to OHM. Straight pins (2) in the socket holes of the removed, Power Button Board's cable connector.
Positive probe lead to one pin, Negative probe lead to the other straight pin.
Press the Power On button.

ANY reading indicates a good Power On switch.
No reading of course means a bad one.
(Remember; the Power On switch is a Momentary Contact Switch.
You will just get a brief reading on the multimeter, if good)

Or you can use a small flat tip Jewelers screwdriver, and TEMPORARILY touch the two contact pins on the motherboard, where the Power Button Board's cable plugs into.

Page 179 for the Display Switch Lid Module,
(HP 417087-001)

http://www.sparepartswarehouse.com/HP,Laptop,Part,417087001.aspx

Unplugging the Display Switch Lid Module from the motherboard, and pressing the Power On button, starts the laptop, you need a new lid module.

Power Button Board, (Power On switch), and Display Switch Lid Module checks OK?

Motherboard problems.
There are Power MOSFETs on the motherboard. These are located close to where the plug of the Power Connector Cable, plugs into the motherboard. (DC Power Harness)

The Power MOSFETs control;
Whether the Battery needs a full charge, or a trickle charge.
Whether the laptop is to just run off of the AC adapter, or Battery.

Look to see if any are blackened, burned, or blistered.
Information using the HP Pavilion dv6000, and Pavilion dv9000 series of Notebook PC's,

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

Just to show the average cost of a Fairchild Semiconductor - FDS6679 - Power MOSFET,

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

One dollar and one penny USD.

Looking at the second photo down on the Mayohardware blog link, look at AO4407.
(Alpha and Omega Semiconductor)

Look to the right of the Yellow circled AO4407. That small rectangular shaped object, with a dark wide band on it, is a Ceramic Capacitor.
There is one above it of the same size, one above that, and one to the right of the top one.

Average cost of them is around 62 cents to 80 cents.

Average cost of a replacement motherboard is around $40 to $60 on Ebay.

That does it for me right now. Post additional questions in a Comment.

joecoolvette

I think you will need to do a system recovery.The symptoms you tell looks like a HDD error because the system does not read the HD.

Go to this LINK and choose the best call for your problem.I choose system recovery and some long procedures had to be done to recver your PC.

hi
  • Decide what kind of reboot you are going to do. A soft reboot is performed the way you are “supposed” to do it. For a soft Windows reboot, go to the Start menu and select “Shut Down” or “Restart.” The computer will then shut itself down. Clicking “Restart” makes it boot up without further intervention from you.
  • Step 2 Perform a hard reboot by pushing the computer’s power button and holding it until the computer shuts down. Wait 45 seconds and restart the computer by pushing the power button again. You may have to start up in safe mode, but that also allows you the chance to restart properly or work on programs in a safer way. This method may cause you to lose data or mess up the operation of some of your programs. But it may be the only option if your computer's hard drive is frozen.
  • Step 3 Power down all of the computer's components. Shut off all of the peripherals you have attached to your computer, and disconnect the cables. Then, plug all of the peripherals back in, and restart your computer. This can often solve problems with your hard drive.
  • Step 4 Purchase and install a program such as Drive Reboot Restore PC 6.0 that streamlines the hard drive reboot process. These applications help prevent the problems that can develop after repeated computer use. They also ensure that your hard drive maintains the configuration you want each time you turn it on.
  • Step 5 Investigate what the problem may be with your hard drive. Because of its delicate nature, your hard drive can very easily be thrown off.

    if you cannot find the switch have a look at the F keys for a key with the wireless symbol shown in that link and use the FN key + the F key with that symbol
    To check that you have a wireless adapter and that it is working OK Press the Windows key (bottom left of the keyboard} and at the same time press the R key, now in the search box that appears - type devmgmt.msc Click on the + sign next to network adapters - you are looking for an item labeled Wireless or 802.11 make sure no yellow ? or ! in device manager anywhere -
