Having problems with your Compaq Presario Notebook ?

Memory slots? I have a toshiba m105-S3041 and every website says it has 2 memory slots upgradeable to 4 gigs. So I buy two 1gig sticks, open the memory cover, and see only 1 stick of 512 RAM. I pull it out and dont see any other! Please help. Roger


Answers :

I found the solution to roger2 and my own problem. The secondary memory add-on slot is on the bottom of the unit, and can be accessed by removing one screw and the slot cover. The other, main memory slot is actually located underneath the keyboard. You should shut down the computer completely, unplug the power plug, and also remove the laptop battery before installing memory. Also, it may void your warranty if you mess around inside of your laptop, so please keep this in mind. You will need to take a very thin flat head screwdriver to gently pry up the panel above the F1-F12 keys. The panel is the entire plastic piece covering the speakers that has the power on, play, stop, ff, rw buttons on it. I used a very thin and flat hair clip that I found laying around to pry up the edges starting from the Pause/Break key moving left towards the ESC key. The screen lid has to be opened all the way for the piece to be completely removed. Once that is taken off, you will see two small screws holding the keyboard in place. Remove these two screws and gently pull out the thin ribbon cable connecting the keyboard to the laptop. The ribbon cable is located directly underneath the spacebar, so move slowly and carefully when removing the keyboard so as not to damage anything. In the center of the exposed area, there is a sort of rectangular metal cover with two screws holding it in place. The one that is about the same size as the slot cover on the other memory slot is the correct one. Remove the screws and open the metal cover. Underneath is the other memory slot. After you install the other memory stick, if you have 4 GB of total RAM, you should know that in 32-bit operating systems, Windows will only be able to use approximately 3.0-3.5GB of RAM. This is because of a limitation of 32 Bit Windows operating systems, and not because of the RAM itself. Only 64-bit operating systems will be able to use all 4 GB. On my system for example, I have the same Toshiba M105-S3041 laptop as you do, running Windows XP Home with two 2 GB sticks, and My Computer properties shows that I have 2.99 GB memory.
The other memory slot is indeed beneath the keyboard. Follow the instructions posted above, but you do not need to remove the ribbon cable for the keyboard. Just fold the keyboard forward and proceed to the screws on the metal cover for the memory slot. Replace the memory under the keyboard and do the same on the back slot. Replace the screws on the keyboard and put the bezel back on and replace the cover on the back. You are then done and will have your added memory!!!
