Assuming you know how to get into your computer and identify the CMOS battery, you just need a pair of tweezers or similar to remove the battery. Once it has removed, take it into a drug store or pharmacy and find the exact same battery, and replace it in the motherboard. If you can't identify the CMOS battery, please let me know and I can help you with that.

How to verify that the CMOS battery needs to replace


<p>The CMOS battery is named after the Complementary Metal Oxide Semiconductor power. The CMOS has the current date and time functions for desktop and laptop computers. It allows the computer to automatically adjust the time, even on computers that are disconnected for long time. When a computer no longer has the date and time and forget it on every boot, the CMOS battery probably needs replacing. Some computers have messages when the battery is weak, while others just lose the current date and time after each shutdown.<br /> <p>Time & Date Errors<span> </span><br /> <p><span> </span><br /> <p>1. Turn on the computer. Look in the task bar at the bottom right. Make sure the date and time is set correctly. Double-click the time and click the up or down arrow to switch to the correct time. Click on the arrow next to month to change the month. Click "OK" when finished.<br /> <p><br /> <p>2. Turn off the computer. Wait 3 to 5 minutes and start the machine.<br /> <p><br /> <p>3. Look on the taskbar to see if time was lost and said a strange date January 1, 2000. Replace the CMOS battery, if this is the case.<br /> <p><br /> <p>CMOS Error Message<br /> <p>1. Look for error messages like "CMOS checksum error", "CMOS Read Error" or "CMOS battery failure" when you start your computer. These errors are caused in the machines shut down for several months or when the CMOS must be replaced.<br /> <p><br /> <p>2. Let the computer on for 24 hours. Restart the computer and find the error.<br /> <p><br /> <p>3. Change the CMOS as the return error.<br />

Low battery warning message on boot up


I'll give you the info for the cmos battery but afterwards observe any other issues with your notebook. Your notebook is not new anymore and may need other servicing besides a new cmos battery.

It should be housed driectly undeneath you notebook on a panel you can remove that houses the ram.

If you still cant find it, you may have to physicaly take apart the unit. I would search under the keyboard and all four corners of the motherboard and center. Just in case.

Let me know how it goes.

P.s: Be very careful If you are not use to opening up notebooks then I suggest taking unit to a professional for them to replace the cmos battery.

P5RD1-V BOOT PROBLEM


The CMOS, which stands for complementary metal-oxide semiconductor, is the hardware component of a computer that supports the BIOS, or basic input output system. The two terms are often used interchangeably, and the two technologies work together to perform the same basic function. They maintain the low-level settings on a computer, letting the computer know, even before the computer's operating system starts, what kinds of hardware the computer has available, such as hard drives and video display adapters. A special battery located on the computer's motherboard powers the CMOS. To reset the CMOS on a Dell computer, briefly remove and then replace the battery
  1. Turn off the computer. Disconnect all cables and detach all devices, including USB devices, from the computer. Press and hold the computer's power button for 10 seconds after it has been unplugged. This grounds the system board.
  2. Step 2 Remove the computer cover. All Dell systems have a cover panel on the chassis that you can remove so that you can access the system's motherboard and internal components. For some Dell computer lines, such as OptiPlex, the computer cover is held in place by a release latch located on the back of the computer. Pull the latch to release the cover and then slide the over up and away. Other lines, such as Dimension, have large, slotted thumbscrews. Turn the screws counter-clockwise until they disengage from the chassis, the slide the cover off the computer. Dell computers often ship with the computer's user guide in CD form or with the guide pre-loaded on the system's hard drive. You can locate the instructions for removing the cover from your particular system in the user guide.
  3. Step 3 Locate the CMOS battery on the system's motherboard. CMOS batteries range in size from size and thickness from about the size of a nickel to about the size of a quarter. The CMOS battery will generally be labeled CMOS on the motherboard and will be the only battery openly exposed on the motherboard.
  4. Step 4 Remove the CMOS battery by prying it gently up out of its socket. The sockets are specifically designed to allow the battery to be replaced.
  5. Step 5 Wait 30 seconds, and then replace the battery in its socket. This will reset the CMOS. Replace the computer cover to complete the process.

Problem of Window XP installation


usually when installation of windows fails is from more than one reason and lets hope that ur hard drive is not damaged (contains bad sectors).
try these steps :
1- use a different windows cd and a different cd rom if u can find one.
2- change the sequense of drives by changing their jumper positions and data cables ( master, slave)
3- try to clear cmos with the jumper located usually near the mainboards battery (short it for 3 seconds)
4- try ( low-level format) to ur hard drive and reinstall windows.

if the message is still seen then your hard drive could be seriously damaged.
