Check the cable going to your monitor and from the monitor going to the back of your computer, take it out and put it back in. Check also the power cable of your monitor.

My desk top comp does not keep the actual date & time,even after repeated corrections


Even when you turn the power off on your HP desktop computer, a small battery much like a watch battery keeps time and stores basic system configuration information.
If this battery runs down or is damaged, it is easy to replace.
Turn off your HP and unplug all cables attached to it.
Unplug the power cable last.
Turn the computer around so that its rear faces you.
The panel on the computer's right side will be attached to the rear panel with two small screws near the top and bottom of the computer.
Remove these with your Phillips screwdriver.
Slide off the side panel and put it aside.
You should now be able to see into the PC.
Locate the CMOS battery.
It will be a small, flat, round metal disc embedded in a cradle near the center of the motherboard (the largest circuit board in the computer).
Use a flat-head screwdriver to release the catch on the battery's cradle and remove it.
Note which way the battery was oriented (positive side up or down) and its voltage (engraved on the battery's surface).
Call or visit a computer supply store and purchase an identical replacement battery, using the specifications gleaned from the original battery.
Snap your new battery into the cradle, orientated the same as the original battery.
Reattach the computer's side panel and reconnect all cables.

I can not find the hard drive in hp pavilion A820n


Thank you for your Service!

The hard drive will be about 4"x5.5"x1" and is almost always mounted immediately below the dvd drives in an enclosure like the one you pictured. But you're in a situation where you don't have a lot of time to get it right, and if you're problem is that you're out of space on the primary drive, you probably need to be transferring to the new drive, and you'll need a working computer to do that. My suggestion is to take it to the repair people at one of the big box stores and have them get it going for you.

When I turn on my HP Pavillion dv6000 it starts up but when it gets to the screen where you type in your password its black with the cursor on it.


marissalynn5, use the Restoration Disk, and choose Non-Destructive Installation when asked. (Repair)

If you do Not have the Restoration Disk (CD);

In the USA the disk is free. The shipping and handling is not.
$17 for a 5 to 7 day ship. $24 for a 2 to 3 day ship.

Call HP Support's toll-free phone number 1-800-474-6836.
24 hours a day, 7 days a week.

Tell the representative that you need the Restoration Disk.
The representative may ask for the Product Number, or the Serial Number.

This is on the Bottom of the laptop in the white Service Tag.
P/N = Product Number
S/N = Serial Number

Turn the laptop on, install the disk in the DVD optical drive, close the drive tray. Perform the above.

If you are not in the USA, here is HP Support Worldwide contact information,

http://welcome.hp.com/country/us/en/wwcontact_us.html

[ If I may. If you are not in the USA, and obtain the Restoration Disk, may I ask how support treated you, and the cost of shipping of the disk? Was the disk free? ]

If using the Restoration Disk does not cure the problem, then I have bad news.

The HP Pavilion dv2000 series, Pavilion dv6000 series, and dv9000 series, have an inherent problem with the graphics chip.

This video explains the problem, and the repair, and possible warranty work by HP,
