Satellite Pro A100-830 with 4 GB of memory but the BIOS tells me that I have only 3 GB

I have a Satellite Pro A100-830 and I bought the maximum memory for what is 2x2gb, for a total of 4 GB in my world. When I put the DIMMs in themselves in a slot, the BIOS reports 2 GB. BIOS Bravo! When I put both together, I see only 3 GB in the bios!

I found this link on the Crucial site. http://www.crucial.com/kb/answer.asp?QID=4251

Suggest page files, peripherals etc. occupy memory on your system at startup, before the operating system is used I guess. If you do not have the maximum memory installed, you should see the total memory. If you got the maximum memory installed, you will not see the memory used by page etc. files. Why would it be? Why you would see 2 GB if you have only 2 GB but then see 3 GB if you have 4 GB due to the system!

Anyone can shed some light on this subject and be eligible or reject the information in this link. I need to replace the memory and/or the pc?

Thank you

Mark

This is not a BIOS problem but a Windows.
I found this info:
Windows XP Professional 32-bit is limited to 4 GB of address space. If you have 4 GB of RAM installed, it won't show 4 GB in Windows. You will probably get what the size of your pagefile subtracted the 4 GB.

Some of this address space is reserved for the hardware and the operating system... so you will never have access to the 4 GB maximum in any case. If you want access to 4 GB of RAM +... your best solution is to pick up XP Pro 64 - bit... but this will only work if your CPU P4 has EMT64. (64-bit)
You can also try to turn on DEP if it is not already enabled... This will also allow EAP that can give you access to all 4 GB

So finally a response:
> Do I need to replace the memory and/or the pc
-> No, everything is ok... you need not to change the hardware

  • Need best driver of ATI X 1600 for Satellite Pro A100-830

    Hey

    I use my Satellite Pro A100-830 (PSAACE-00W002EN) for the most part to play my games, but unfortunately I can't. It seems that Toshiba doesn't provide good enough graph-drivers because every time I play, for example: half-life 2, I get this error specefied: internal driver error in IDirect3ddevice9::present()

    I tried to reinstall my computer all with CD distribution which followed with my PC, but this work of t is not a long time. I also tried to download than the latest ATI drivers, but they can not be installed, nor OmegaDrivers (Installable but didn t work).
    I use Windows XP and I have all the updates of 'Windows Update'...
    Just when I reinstalled my computer, I downloaded all Windows, then the most recent BIOS updates, and after that, I deleted the ATI driver that was limited to the CD and installed the ATI driver 'later' of Toshibas own homepage.
    (Not only Steam-games doesn t work, almost none of my games...)

    Please help me on these "desperate times." Would be happy if you could write the answer directly to my email address:

    Hello

    To be honest, you are not alone in this and many laptop users want to have better performance and play the latest games which can be played with the latest and newest materials. If you have a portable way but want to have maximum on graphics performance.

    Sorry but I think you wait a little too long. We are talking not on desktop computers and notebooks. As a player, you understand without doubt that high-performance graphic has a result a lot of heat, and it can be very dangerous for the portable equipment (placed on the square). Using the most recent and better display drivers will require you probably to a graphics card to work under pressure but the result may be overheating or even damage the material.

    Be reasonable and understand that laptops have lower graphics performance and laptop manufacturer has only one priority: to protect the equipment. Because of this there not much updated graphics card drivers.

    I don't really know what games you try to play, but I tested my old M70 (also ATI) graphics card with several games (not later) and it runs good.

    Bye and good luck!

  • Satellite Pro A100-830 - HDD upgrade questions

    I'm a complete noob so please forgive my silly question!

    I would like to replace my laptop HARD drive, is there any combatibilty issues I should be aware of, or is it just a case of getting a HARD drive 2.5 "?

    Is it easy to buy an external and use the internal drive inside the case?

    This seems to be the best way to the value of doing. Specific recommendations?
    Thank you!

    Hi magicmat,

    Generally upgrade the HARD drive is not complicated, and that's why you only have to remove the cover of the HARD drive on the lower side of your laptop to replace the HARD drive.

    Satellite Pro A100 already use hard disks with SATA interface so you have such a HARD drive. In addition, I would recommend a 5400 RPM model because it s quite fast and doesn t a lot of power.

    So that s what you need to know about upgrading. Theoretically, you can use the old or an external HDD with an external HARD drive enclosure. Also no problem. :)

  • Satellite Pro A100 (PSAAC) with WIN XP - shutdown problem

    I have problems with my laptop stops not when I ask to do. The message that TSrsTRAYWND isn't closing arrives and I'm invited to manual closing. Even if I do this, the machine "blockages" and does not shut down. I tried the boot without failure and closure then - it does correctly, but then when I start normally and try to stop, it is up to the "hanging" again. The operating system and other programs are fully up-to-date.

    Can anyone suggest one solution, from other online for one, I see that others have the same problem, without a solution yet.

    In anticipation of your help, thank you!

    PS - I can't find any reference to the TSrsTRAYWND anywhere.

    Hello

    I tried on my laptop for a TSrsTRAYWND.exe file but I could t find anything. If you search for this file on the HARD drive you get a result?

    I think it has something to with the drivers/software that will be loaded on Windows start. You should try to disable all programs in msconfig-start up that you don't need online. Then try again.

    Sorry, but everything that s what I can say at the moment.

  • Satellite Pro A100 - CD/DVD drive is not listed in the Manager of peripherals and BIOS

    Can Hi anyone tell me what is wrong with this laptop?

    The problem is im using my DVD - ROM drive and it stops working. I went into Device Manager and it wasn't there and it was not in my list of drives. I went and checked the BIOS, it is not listed there either and the BIOS pick up all get them is check the cable or the conection.

    Would be grateful if some knows what happened or if my hard drive is gone.

    Thank you

    Hello

    If the CD/DVD drive is not listed in the Device Manager and BIOS, it seems to be defective and must be replaced.
    What do you think about this?

    You can exchange the car yourself. Check for a compatible CD/DVD Player user manual or go to an authorized service provider. Technicians can order a new drive to swap.

    Sorry, but if the drive is not listed in the BIOS seems to be defective.

    Good bye

  • Satellite Pro A100-830 - clean install of Windows 7

    I want to install a new larger HARD drive in my machine and want to try Windows 7 while keeping XP Pro on the old HDD (just in case).

    All the world did this on this machine?

    Were there a driver or compatibility problems?

    The machine is certified "Vista Capable" so must deal with Win7 if the drivers are not a problem.

    You can install Windows 7 on this laptop.
    It shouldn't be a big problem.
    IF you miss a few drivers, then you can search for these drivers manually.

    Have you tried a BIOS update?
    This you will find also on the Toshiba site:
    http://EU.computers.Toshiba-Europe.com

    You have disabled all the security features for testing?
    I mean hidden SSID, MAC address filtering and so far. Maybe that's the problem.

    Have you already checked the BIOS? How much RAM show the BIOS?
    And what kind of modules you have exactly?

    Normally, it should be possible to use full 4 GB of RAM on a 64 bit OS as your laptop also supports 4 GB.

    Maybe you should also try updating the chipset driver. You can find it on the Toshiba site.

  • Cannot use wireless LAN with my Satellite Pro A100

    Toshiba Satellite Pro A100-830
    NETGEAR DG834G

    Can not use the Wi - Fi connection. When you use "Free Config" to find peripheral wireless the popup "this connection is controlled by other software. I don't know what that means and what software controls the connection. I have other laptop which is duly connected by wireless. I'm ok with wired connection.

    I don't know much about the technical aspects and therefore ask for help so any reader can.
    Thank you
    Kris

    > Can't use the Wi - Fi connection. When you use "Free Config" to find peripheral wireless the popup "this connection is controlled by other software.

    You may not use the ConfigFree for configuring Wlan but own Vista configuration options or the WLan configuration tool like Atheros Clint Utility or Intel ProSet utility. It depends on the WLan card which utility can be used.
    Card Intel-> Intel ProSet utility; Card Atheros WLan-> Atheros Clint Utility

    I guess the message + this connection is controlled by other software + appears because one of the above options controls the WLan.

  • Satellite Pro A100 - recovery mode sleep with keyboard or media remote

    Hi guys

    I have devoted my Satellite Pro A100 to be a media center which is located under the TV and can play media network and DVD etc..
    It is using Vista.

    I want to set up, is that the lid is closed 24/7 365 days and when I want to use I just press "SLEEP" or power button on the remote control or the keyboard and it fires up ready for action.

    POINT TO THE NOTE. I did it successfully with my OLD Tecra M3. However, was too slow for vista and media center

    However, I put the power settings I want etc, close the cover nothing and activated standby hybrid (favorite sleep).

    Now I CAN put it to sleep with the remote control or the multimedia keyboard. BUT I can wake up?... NO!. I thought about everything... went to the Device Manager and made sure that all the options for the remote control and keyboard and USB receiver are set to WAKE FROM SLEEP. The only thing to wake up it is the power button - which defeats the purpose of it sitting there like a dvd player.

    awake when the remote control and keyboard function very well - I made sure that the batteries are charged.
    I have the latest version of the BIOS and speaking of BIOS there is no option power S3 I noticed, but then there were not on the M3 and it worked very well in terms of sleep and wake up with the IR.

    I come to the forum because even though I know that some older systems will not work with vista - IF the M3 will work - I'm sure that the A100 twice as new and powerful.

    Has anyone had this before - that I missed it must look me in the face.

    Thanks in advance.

    PS Also lately the touchpad played upward IE left and right clickers Exchange feature so one second your work as normal the next minute you click left and right clikc menu appears. Reset the synaptic reinstalled - rebuilt - BIOS - no difference.

    When I worked in management for a large company when it started happening was not good news - it's a bad news?

    Hello

    I m not very well why it doesn t on your Satellite Pro A100 and why it works on M3.
    But the fact is that the Satellite Pro A100 doesn t support the FIR (Fast InfraRed) port and the
    Tecra M3 supports the fast infrared port.

    Maybe this could be the reason why you can not activate the laptop using the infrared remote control multimedia.

  • Satellite Pro A100 and load problems

    Hello everyone. New Member here.

    Got a huge problem with my laptop. I have a satellite pro A100-830. Part number: PSAACE-00W002EN. About 2 years ago

    I can run on the current system. But it will not work on battery. I just bought a new battery and it shows on the computer.
    I get indications are:

    battery charge amber lit.
    Light on power
    Power meter indicates the battery charge. I connected new battery and it shows 47% and now 3 hours later its still 47%
    If I unplug the power to the computer shuts down and will not work on battery.

    the AC light seems to be slightly duller than the one next to him, if that makes sense.

    Ive tried updating the BIOS etc but I'm ideas if im honest as im not a computer pro. I searched the internet but I can't find an answer

    Huge thanks in advance

    Stand by.
    We need more explanation here.

    You have the same problem with the battery and you have bought one new in the hope that everything will be OK?
    Have you noticed the same problem with the battery?
    You bought original Toshiba battery?

    In my view BIOS update won't help you much. I think electronic power is responsible for this BIOS update ahs no influence on this.

  • Satellite Pro A100 - can I exchange the CPU?

    Hello world

    I have a Satellite Pro A100-198 with a core duo processor. I would like to replace the processor of a Satellite Pro A100 830, which is Core2Duo in the Pro A100-198. They both have the same chipset-expected-they be any problem with that? This would increase the clock speed of 1.66 GHz to 2.0 GHz. They all have two Intel 945 PM Express chipset.

    I just upgraded from XP to Windows 7 32 bit and the performance score is 3.4. My BIOS version is 1.9 and I see there is an upgrade to win all the version 6, but I can't find the BIOS version history - it is better to upgrade. For the moment, I'll see if there are problems.

    Thanks in advance Mick

    Hi Mick,

    As far as I know the two books belongs to the PSAACE series. Can you confirm this? You can find this information on the underside of the laptop.

    Normally if the books belong to the same series, it should be possible to exchange the CPU. They use the same hardware, so you can exchange.

    But don t forget this isn't supported CPU upgrade. If you have the warranty you will lose it. Other s CPU are pre-tested not on your laptop.
