If you open the case and look at the motherboard you should notice a small, round, silver "watch" battery in a socket somewhere. This is the battery that needs to be replaces. Check this link for further instructions.

There are three versions of the HP Compaq D530.

1) The Convertible Mini-Tower Desktop PC
2) The Small Form Factor Desktop PC (SFF)
3) The Ultra-Slim Desktop PC

The reason I bring this up is that if I knew what EXACT desktop computer you have, I could give you exact information on how to access the CMOS Battery, and replace it.

I'm going to use the Convertible Mini-Tower Desktop PC for an example,

In the list click on >
Manuals, (guides, supplements, addendums, etc)

On this page scroll down to the bold heading > Service and maintenance information

Click on the file name >
HP Compaq Business Desktop D500 Service Reference Guide, 5th Edition
Allow the PDF file to fully download.

Use this same procedure on the HP Compaq D530 you have.

In the Bookmarks menu to the left, scroll down until you come to the heading >
Removal and Replacement Procedures - Convertible Minitower (CMT) Chassis

(If you have an SFF, or Ultra-Slim, it will be listed at the end of Removal and Replacement Procedures, instead of Convertible Minitower)

Now scroll down to > 6.15 Battery, and click on it.
Now go to the pages that follow.

(NOTE* You may wish to reduce the view size. Click on the Zoom Out icon.
{Circle at the top of the PDF file with a Minus ( - ) sign in it }

The CMOS Battery is a CR2032. A type of watch battery, found in an abundance of stores.

Why would my check engine light came on after I replaced my battery lights on my radio & clock are dim, sometimes there fine.I plugged an OEM meter in it's givingt he code p1633 What could this mean?

Fords have a problem if the battery runs flat or they are disconnected thus removing power from the onboard computer(s).

You may need to take the vehicle to a dealer service center to rectify the electronics problem for you and reset your computer.. To avoid this problem you need to connect up a second power source to the main leads to the battery while you are disconnecting those leads and replacing the battery so as to retain power to the onboard systems at all times.

In any event here is an item that may help you...........

New battery, alternator, starter and the battery still wont stay charged

voltage regulator is what would cause this problem, but according to alternator stats on this veh it shows the voltage is regulated by the onboard computer. it appears that this is what may be the problem. (initially were the terminals crossed,and poss short the system? if so then looks as though you would need to replace the ecm/onboard computer)

I need to replace the onboard battery

If by on board battery you mean the cmos battery, then you would only need to replace it if your computer is constantly forggetting or losing the correct time and date..

If it is doing som the onboard battery is round and flat ( like a watch battery) and is usually accessed either under the keyboard, or by removing one of the plates on the bottom of the laptop..

Make sure the main battery is removed and the power cord is removed before replacing the onboard battery.

On boot up the bios is stating the CPU was changed. But it was not.

Usually that is the first signal that the battery is drained and needs to be changed. Yes you are right, go ahead and change the onboard battery and set the time & date after that.........sodeep

Im getting a boot time error called CMOS error and then i have to enter the sytem date and time every time i start the pc. After that it shows me an error like Invalid System Disk. wht does tht mean?

The CMOS error is caused by a dead motherboard battery. There is a small battery on the motherboard Usually a 2032 battery. The dead motherboard battery could also cause the Invalid system disk because a dead motherboard battery will also cause the motherboard to lose the Hard drive settings.
