Memory Install Problem. I have just tried installing an extra memory module to my HP Compaq V3000. Was 512K, tried adding 2G. The laptop stopped responding and now won't boot at all even when I removed the extra memory module. It doesn't even show the POST but does flash the power led and signal 4 beeps as some error code. There is no reference to error codes in the manual and no reset pinhole for BIOS. Any suggestions? Dutchie140

4 Short beeps would indicate during POST (Power on Self Test) there is a initialization issue with added hardware. The DIMM you added may not be compatible, or installed in the correct order.
1. Remove new memory completely, and see if machine starts
2. If you have original memory module still installed, remove it and try new one by itself.
3. If that works, put newer larger module in the 1st slot, and move original in second slot, and try again.

The system can automatically adjust memory settings (speed and timing) itself from the SPD module on every stick of RAM. However if the settings are drastically different, it can cause problems. Generally it will run as fast as the slowest module, but now always, sometimes causing the slower module to be attempted to run out of spec and cause boot issues or system instability.

Good luck!

Upgrading memory helps improve system performance. By following the step-by-step instructions in this document, you can successfully upgrade random-access memory (RAM) for all HP and Compaq notebook computers. While the graphics might not match your specific computer model, the steps will work. Read all instructions carefully before attempting memory installation. NOTE:Do not purchase memory modules until you know the type of memory used by the computer, the maximum amount of memory the computer can use, and the memory slot configuration. How to find the product number of your HP notebook PC To order replacement internal components such as memory, you must know the exact product number of the computer. For many HP notebook PCs, the product number and serial number are printed on a label on the bottom of the computer. Also, the product number and serial number are printed on the outside of the shipping box that you received when you purchased the computer. Product number locations can vary, and there are numerous methods to find the product number of your notebook. NOTE:A general family name may be imprinted on the case near the keyboard or on the frame around the display screen, but this does NOT provide sufficient information for ordering replacement parts. Finding memory information for your computer model (amount installed, maximum supported, and type of memory) Important memory upgrade information is in the specifications document for your HP computer. To find product specifications, browse to the Product Information category on the support page for your computer model. Refer to the Memory section within the product specifications document for memory information specific to your computer. Among the information listed, take note of the following items. It will be useful when purchasing memory and when performing the next steps. Amount of memory installed - The current amount of memory installed on your computer. Go to Verifying how much memory can be added to verify the amount of memory currently installed. Maximum memory supported - Subtract the amount of memory already installed from the maximum amount supported by the system to determine how much memory to get. You can also buy the maximum amount allowed and replace the currently installed memory. Once you know the maximum for your system, check Maximum memory supported by operating system to see how much memory your version of Windows will support. Use the lower of these two numbers as your maximum memory. Type of memory (including speed) - It is recommended to get the same type of memory (same size, same speed, same manufacturer) for each slot. For best performance, get the fastest memory that the motherboard supports. CAUTION: Due to the variety of possible configurations, some motherboards might not be able to properly configure memory if the array of small outline dual in-line memory modules (SO-DIMMs) contains a SO-DIMM that is not from the same manufacturer, has a different CAS latency value, or has a different density value (high and low used together). Make sure all SO-DIMMs meet the requirements of for the motherboard (the information listed in product specifications), have the same part number, are from the same manufacturer, and meet the basic memory requirements for your motherboard. If not, make sure that you can return the memory if it is not recognized by the system after you install the new memory. Determining where your memory is located Memory is installed inside of the memory module compartment, which is located on the bottom of the computer on most HP notebook PCs. Some HP notebooks are designed with the memory module compartment under the keyboard. If the memory module compartment for your particular notebook is located under the keyboard, HP recommends that you contact an HP-authorized support or repair facility for assistance in ordering and replacing the memory. Verifying how much memory can be added Prior to upgrading memory, you need to verify how much memory you currently have installed to determine how much memory can be added. Using your User Guide for memory installation instructions The User Guide contains helpful information and pictures showing how to remove and install memory in your specific notebook model. A copy of the User Guide is stored on the hard drive, and it is also available for download from the HP Web site. Installing memory Notebooks are designed so that additional memory can be added using a Phillips screwdriver. Use the following steps to install memory in an HP or Compaq notebook computer. After reviewing the following steps, if you are not confident in performing the installation yourself, contact an HP authorized distributor for technical assistance. NOTE: If someone other than HP installs or upgrades the memory, any damage caused by the memory and/or by a person trying to install or upgrade the memory is excluded from coverage under the product warranty. The customer assumes all risk and liability for damages for any such installation or upgrade. NOTE: Important! You might find that your HP or Compaq computer is able to support a physical installation of 4 GB or more memory. However, this maximum memory might be further limited by the operating system not being able to address the full range of physical memory. 32-bit operating systems, such as 32-bit types of Windows 7, Vista, and XP, can address approximately 3.3 GB. This limitation is present on all 32-bit hardware and 32-bit operating systems and is not limited to HP and Compaq PC systems or Microsoft software operating systems. Verify the computer is turned off, not simply in sleep or hibernate mode. Disconnect the A/C power adapter. Turn the notebook over and place it on a firm surface. Remove the battery. Use a Phillips screwdriver to remove the cover on the memory module compartment. (See the User Guide for instructions on how to remove the memory for the specific computer. If you need help finding the User Guide, refer to the section Locating your User Guide for memory installation instructions .) With the cover removed, and before you touch the memory, ground yourself to discharge any static electricity. NOTE: To ground yourself, and discharge any static electricity, place one hand on the case of the computer and touch the other hand to a metal surface or grounded object, such as the metal part of a lamp. To release the memory, use a small wooden tool, or fingernail, to spread the clips holding the ends of the memory in place. One side of the memory will rise when the clips are released. Remove the memory and place it in an anti-static bag. Remove the new memory from the protective anti-static bag and hold the memory by the ends. Place the gold contacts into the connector (bracket) and gently, but firmly, press the memory into place. The clips will click when the memory is properly seated. Replace the cover and tighten the restraining screw. Replace the battery and A/C power. Turn on the computer and allow it to reconfigure and recognize the additional memory and improve performance. Buying memory HP recommends purchasing memory directly from HP, an authorized HP dealer, or from a reputable computer parts supplier. You can buy computer memory from most local electronic stores and online shopping sites (such as www.crucial.com or HP , for example). Many of the online sites partner with HP to automatically suggest the correct type of memory based on the model of your computer. Before purchasing memory, make sure you know how much memory you need and what type of memory is compatible with your computer.

The installing one RAM module at a time to see if both RAM modules work.
If they both work then they may be incompatible.
Try using the same make and type RAM modules.

Hi,

As far as I know, the machine supports 4GB of ram, so you purchase the ram modules from a pc parts dealer and install them inside the machine, removing the existing ram, there are 2 slots, so you need 2, 2GB cards.

You do not require any drivers or bios update.

Windows will need to be upgraded to 64Bit version if you wish to use the full capacity. as normal windows is limited to 3-3.75GB

Further questions? let me know.

Hi, Yes, it would be best to take the old RAM out. I am assuming that this is 1 stick totalling 2GB. Optimally it would be good to have 2 x 1GB modules totaling 2GB, so they could work together. Otherwise, yes, just remove the the old ram and install the new module. If you are running a 32bit operating system, 3GB is all the system can use anyway. Hope this helps!

You only have one slot so you pull the existing memory and put in a 2gb card. Kingston number is KTH-ZD8000C6/2G 2GB 800MHz Module

The memory slot is most likely in the bottom of the laptop and its hold closed with 2 screws.

Some laptops have the other memory module under the keyboard, if the other memory module is not in the bottom of the laptop, you would have to unscrew the screws from the bottom of the laptop that are under the keyboard, those screws may be marked with K/B (meaning Keyboard screws)

Then you may have to remove the plastic cover from the top of the keyboard which is between the display and the keyboard, in most cases this is hold in place with just plastic clips, you can remove it with a small flat screwdriver starting at the display hinges and then working your way slowly to remove it completely, if it really resists alot, check for screws in the bottom and the nearby areas and unscrew them, we don't want to ruin it.

Then you should be able to unscrew the rest of the screws on the keyboard and take it up, and you should be able to get to the 2nd memory module.

About the wireless card, you can use a USB, a PC card or possibly a internal card if the laptop has room and a connector for it inside, I would recommend you go with either a USB stick or a PC CARD, take the laptop with you to a local shop to find out which one would be the best option for your laptop.

let me know if you need furhter assistance.

Compaq Presario V V3000 Specification Memory Type: DDR2 SODIMM 200pin DDR SODIMM:
DDR, double data rate is a type of SDRAM in which data is sent on both the rising and falling edges of clock cycles in a data burst. It is usually referred to as DDR as opposed to DDR SDRAM.
SODIMM, small outline dual inline memory module. Smaller and thinner than standard DIMMs, SODIMMs are typically used in laptop computers. Memory Speed: PC2-4200, PC2-5300 Chipset: Intel 945GM Chipset :
A group of chips that together make up a complete computer processing unit, usually on one circuit board (the motherboard). It may include the main central processor, graphics processors, secondary cache memory, and input-output controllers. Memory is one component controlled by the chipset. Standard Memory: 512MB Removable Memory Slot(s): 2 Max. Memory Per System: 2048MB (2GB) Max. Memory Per Slot: 2048MB (2GB) Dual Channel Memory Support: Supported Dual Channel :
A development in motherboard and chipset design that allows for increased bandwidth transfer when using two or more memory modules in separate transfer channels. These separate channels allow each module access to the memory controller, increasing throughput bandwidth. It is a good idea to use matched pairs of modules to ensure the best compatibility for dual channel operation. Tri-Channel Memory Support: Not Support Tri-Channel :
A development in motherboard and chipset design that allows for increased bandwidth transfer when using three or more memory modules in separate transfer channels. These separate channels allow each module access to the memory controller, increasing throughput bandwidth. It is a good idea to use matched three modules to ensure the best compatibility for tri-channel operation. Install Memory in Pairs: Not Required Install in Pairs :
Memory modules must be installed in pairs of matched memory size. This means that if you purchased your computer with 128 MB of memory installed and you want to add another 512 MB of memory, you must remove the two continuity modules and replace them with two 256-MB memory modules.

The other memory may be soldered in. Check your manual and see if it has any information on additional memory. If you only have on expansion slot you may have to buy larger memory chips. like instead of 2 chips 1 gig each you may have to purchase a 2 gig chip. Computer companies usually make the chip installation easy to get to on lap tops.
