Pavilion ze4900 RAM question

Does the ez4900 have any RAM besides what is in the RAM bay on the bottom of the chassis? Some laptops have some RAM soldered into the main board and their bays are for expanding on that. The ez4900 I was given has no RAM cards in the bay. When turned on, it beeps 4 times but shows nothing on screen (screen stays black) and no keyboard actions seem to have any effect. There is a slow blinking blue light on the front edge that indicates suspend mode, and the battery light it on. Power supply has been checked and is working. I have not yet found an explanation on line for what 4 beeps may mean (or any beep codes for this model). So I'm wondering if the problem is that there is no RAM at all.
Thanks!

Yes the problem is no RAM. Laptops with onboard RAM have not existed for many years because if that RAM goes bad the whole thing is junk.
You need laptop DDR memory which is easy to find. I have a drawer full of 128 meg laptop DDR sticks I would give you. It will not do anything without memory.

  • HP dv9629ca Laptop (Ram Question)

    Here is a RAM question. The Laptop had 2 one Gigabyte SO-DIMMs with them both installed the PC would not boot. the lights would come on but the screen remained black. I thought it was a RAM problem since when I would only put in a single stick of RAM the computer Booted no problem. I figured the one ram was BAD. Yet when i bought a 2GB SO-DIMM and added it to the 1GB already inside the computer wouldn't boot just like before. so I removed both rams and Put the 2GB stick in where the other was working and It shows 2GB now. I Know the Laptop maxes out at 4GB of RAM with a 64bit version of Windows installed. Is it possible to find a 4GB SO-DIMM and put it into the Slot that works or will it only accept a maximum of 2GB per Slot?
    Laptop Details
    AT newegg.ca they have a Single SO-DIMM that is 4GB the Laptop Max is 4GB. Not sure if it would read 4GB coming from a single SO-DIMM

    Here are the specs for your HP Pavilion dv9629ca Notebook Computer and here is the HP Pavilion dv9500, dv9600, and dv9700 Entertainment PC - Maintenance and Service Guide for your computer. Both pieces of information indicate that 4GB (2 X 2GB) is the maximum. 2GB is the largest size supported in each slot.
    You may wish to clean the slots or reseat the memory... you may also want to inspect the slots for debris or bent contacts.

    It means the hard drive has likely died. It is going past where the hard drive would be in the boot order into network (PXE) boot. To double check, tap F10 as you power up and see if you can find the hdd in the BIOS. If not you just need a new hdd.

  • Blue Screen of Death After Trying To Install Windows On Pavilion ze4900?

    After my hard drive died in my Pavilion ze4900, I replaced it with another notebook hard drive I had laying around.I also tried installing Windows XP home from a Windows installation CD, the same OS the laptop had before the hard drive died. All went well until the laptop was done loading all the installation files, instead of giving me the option to either install Windows or repair Windows, the laptop ends up showing me a blue screen with the message: " A problem has been detected and windows has been shutdown to prevent damage to your computer." What can I do to resolve this issue? I have installed Windows XP on another computer using the same CD, so the CD hasn't gone corrupt and the replacement hard drive is barely used. Any help would be greatly appreciated!  

    , Hello and thanks for posting on the HP support forums.  The first thing you will want to check is if there are any issues with the hard drive you put in.  Run the BIOS diagnostics for the hard drive and the hard ware to make sure there are no issues. HP Notebook PCs - System Diagnostics (F2) And. HP Notebook PCs - Testing a Hard Disk from the BIOS Please let me know how things go. Thanks again for posting and have a great day.

  • Pavilion ze4900 shuts down in minutes, no error messages

    I have a Pavilion ze4900 and it will only stay on for a few minutes and then quickly shuts down.  I have disassembled the laptop & powered the unit back on to watch the cooling fan. There is only one fan with heat sink for processor.  There is not any dirt on the fan & the inside is clean.  I never see the fan run but then again it doesn't have a chance to get warm.  I am thinking about changing the fan but not sure if that is really the problem. There has been no change to the bios since it was purchased. A computer store said it wasn't worth fixing but I am attempting to do it myself so what would cause this quick shutdown?  The system will bootup & I can login as normal.  I have at times been able to view files before it shuts down.  There are no error message on the screen when it turns off.

    I don't think the processor would get hot enough to need the fan in just 2 minutes. The cooling fan and heat sink don't have any build up of dust. I did completely remove the cooling fan and heat sink which is one unit. I didn't see any heat sink compound between the processor and heat sink but, again, I don't think the shutdown is heat related. If the laptop was hopped up so it runs at above design speed then the processor could get hot very quickly but this is all factory without any modifications. It is a Celeron M processor which is pretty bottom of the line.  Maybe the processor is bad or something on the system board is bad.  I can't really test the processor or system board because it shuts down to quickly.  I don't want to pay money to send it to a repair shop because they are going to want $200 or $300 ++ because of labor to disassemble this thing.  It took me 3 hours to take out a big pile of screws which I can only hope that I can get it back together if I manage to find the  defective component.  I am running the PC with the case off and an external fan pointing directly at the processor and system board so the cooling fan is probably not needed because of the airflow I am providing.

  • VERY SPECIFIC RAM QUESTION (not answered in prior topics)

    I have a very specific RAM question. I've been pouring through the discussions and I see TONS of stuff about the proper way to upgrade RAM. I've done that before without incident, but here is my dilemma:
    I'm using the 3.0Ghz, 8-core, MP currently with 8GB of the 667Mhz RAM (8x1GB). The memory is all matched from OWC and I have had no problems.
    I just bought 16GB of new RAM from OWC (4x4GB).
    I'm going to remove all 8 of the current 1GB DIMM's, and place two of the 4GB DIMM's in slots 1 & 2 on riser A, and two of the 4GB DIMM's in slots 1 & 2 on riser B. That will give me 16GB's in matched pairs on slots 1 & 2 of both riser A and B.
    My question is this: Should I install two of my old 1GB DIMM's in slots 3/4 of riser A, and two of the old 1GB DIMM's in slots 3/4 of riser B (for a total of 20GB's)?
    I've read that having all 8 slots filled = better performance but I'm not sure the mix of 4GB DIMM's and 1GB DIMM's.
    Any Thoughts?
    Thanks So Much,
    Tom

    Optimally you want matched quads in each Riser. However, Bare Feats did some memory benchmarks that you might wish to read regarding memory performance versus different configurations. As for proper installation see the following:

  • Can i upgrade an hp pavilion ze4900 laptop with an ssd?

    The hard drive is failing in an hp pavilion ze4907wm (ze4900 sold thru walmart). 
    Are there any special considerations for replacing the hard drive (capacity limits etc)?
    Can I put an PATA SSD in it?
    Thanks

    View Solution.

    If you can find a PATA SSD then probably. You'll need to make sure that the jumper is manually set to Master. There also might be compatibility issues.
    Overall, I'd recommend just replacing it with a regular PATA HDD ... There is less of a chance of an issue.

  • Hp Pavilion dv6765ev RAM upgrade

    Hi all,
    I have an Hp Pavilion dv6765ev notebook, which I own since April 2008. It came with a total of 2GB RAM (2x1GB). Since it is already 6 years old, I am making some changes (for example, I ordered an SSD to replace the original HDD disc), and I was thinking of upgrading RAM.
    I would like to be sure what RAM to buy. If I am not mistaken, I can upgrade up to 4GB, it's DDR2 (2x2GB)? For example, is the following kit ok?
    MUSHKIN 996559 4GB (2X2GB) SO-DIMM DDR2 PC2-5300 667MHZ DUAL CHANNEL KIT
    Do you have a specific brand to propose? What should I pay attention to?
    Thanks in advance!

    Hi
    This is the manual: http://h10032.www1.hp.com/ctg/Manual/c01295877.pdf
    Specs: http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay?javax.portlet.begCache...
    The RAM config you chose is correct for your system.
    The brand details I don't know, but it had good rating in newegg-
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820146697
    You can put the 2 memory sticks replacing the two pervious ones.
    For related info:
    The part numbers listed in manual for replacement if ordering via HP post store are:

    You can upgrade to 2Gb of RAM but this will only run at 667 MHz.  An example of compatible memory modules is on the link below.

  • MSI 915p Thoughts & ram questions

    Hi All,
             I'm thinking of buying one of  MSI 915P neo2 Platinum motherboards, but i have a couple of questions. Firstly i'm having dificulty finding reviews for this mobo, so i've come here to see what you think of it (unbiased of course). Secondly i'm confused over what type of RAM it supports, some parts sellers list PC4200 others PC4300, i'm even seeing the newer PC5300 being mentioned. And finally what the difference between PC4200 & PC4300.

  • Mac Pro 8 Core (2008) Hard Drive & Ram questions

    Hi there,
    I recently purchased a Mac Pro 8 Core 2008 Model with 2Gb ram and 320Gb Hard Drive (Got a great deal on it... paid $1,500.00 for it!!). I bought this computer exclusively for audio production work. I know I can upgrade up to 32GB of ram if I wanted to however, I have heard that the system won't recognize 32GB ram when running 32bit OS & Applications. I use Ableton Live 8.2 (32bit capable) and Logic Studio 9 (32bit & 64bit capable).. what is the highest amount of ram I should upgrade to without overkilling it? In other words... what is the highest amount of ram I can upgrade to that I will actually notice the difference and that the system will actually use @ 32bit?
    Second question is regarding hard drives... I need at least 320GB for OS and core applications and at least 1 TB for storage... what is the most efficient, fastest and least expensive to upgrade the storage on this machine?
    I really appreciate your comments on this one.

    Someone with Mac Pro, but on OS X 10.6 Install forum, like some, has full suites of CS5, FCP and others, and had run out of space literally on 150GB boot drive.
    Apps like iDVD tech note recommended the boot drive have 24GB of free space (unfragmented for best burn performance) to burn dual layer.
    X-Plane can go anywhere but uses almost 60GB for full world support.
    My rule of thumb is 50% free on boot drive to avoid fragmenting free space such that it causes problems and there is always good performance overall as well as for read/writes.
    To say someone doesn't need xyz when maybe they rre right, and to argue with their own math?
    OS X does not support TRIM or I'd see if you can go with 120GB SSD. One way to slim down boot drive of course, maybe you have, maybe not,
    Move all the data and media files possible off the boot drive can save 100GB and improve I/O at the same time.
    Move the entire home account folder (the above leaves a smaller 1GB home library only on boot drive) which really isn't totally necessary but nice for some.
    WD Black Caviar 2TB $170 is fast and nice or $89 for 1TB (if you think you need A, then get 2 x as much storage).
    2008s don't use 8GB DIMMs and 32GB is as far as they go.
    ATI 5770/5870 or even Quadro 4000 graphics
    did it come with a 4870? or 8800GT?
