Hello,
These beeps are error code and two short beeps during start up normally refers to RAM or memory not being detected. You can try to reseat the RAM modules or ask someone who knows how to do it. If it will still be the same, it means that the RAM is defective and consider replacing it.
Cheers!

If you get several beeps then there is a video problem. The video card uses shared RAM (part of the main RAM) and if the RAM is faulty the laptop won't boot up.
You might have incompatible RAM, try to use the same make and speed RAM as the original.
One of the RAM modules may be faulty.
Try installing one 256Mb RAM module then boot up the Toshiba, if it works the try the other RAM module.

Hi,

If the original memory card (RAM Stick) is working, then it just means two things; either the 2GB memory card is defective or incompatible with your system. Incompatible means the type is not for your motherboard or the 2GB is more than what your computer can handle. You dont need any drivers for your memory card (RAM).

Try to install a 1GB first and check if it is working. make sure the type (ddr,ddr2,ddr3) is the same as the original and the Bus speed (3200,667,800,etc.) is the same as well to eliminate incompatibility errors.

Hope this helps.

Toshiba Satellite How to remove keyboard and upgrade memory modules. This post was written by cj2600 on April 28, 2006
Posted Under: Toshiba Satellite A20/A25 --> Removing and replacing memory on a Toshiba Satellite A20 or A25 notebook is not as easy ad it should be. Both memory modules are located under the keyboard. A laptop keyboard has to be replaced in order to get access to the memory modules. Before you remove the keyboard do not forget to remove the laptop battery or you can damage the laptop. Be careful when you remove the keyboard securing strip; do not bend it too much. To remove the memory module from the slot on the system board, release the latches on both sides and the memory module will pop up. It will stay at a 30 degree angle to the system board. Firmly grasp the memory module and remove it from the slot.

While turned off..You could take out the CD/DVD drive, HD, all the memmory(1 or 2 modules) and If you know how, even BlueTooth and modem and WLAN mini PCI/PCIE modules. Then try to start it. If you hear 2 beeps followed by any other numbers of beeps(2_x_x)...then you can be rather glad that your motherbord (still maybe!) works ok. If you hear other kombinations of numbers of beeps(1_x_x, 3_x_x or 4_x_x) then you may have problem with the motherboard :( .. in case you hear the 2_x_x beeps you have a memory problem..shut down the laptop...now put only one of the memory modules(if you have 2) and boot up...if you get the picture you should be able to see any BIOS POST warnings/error messages..if you still hear the 2_x_x beep comb. you have a memory problem..then you should buy a new memory! if you dont see any picture on the screen it could be the Graphics card problem or yet another indication to memory problem...if you get sure that the memory and the motherboard are ok then put in the components back in and boot after each to figure out witch part is problematic...

Good luck!

Here is the link for the Toshiba Satellite M105-S1021 manual. It is zipped and you can download it to your machine. It will tell you exactly how much RAM you can hold and where it is located.

Please don't forget to rate this solution.

dont be silly. You need tech support

click start,all programs,accessories,system tools,system information......check for conflicts..go into device manager and change resoures or if you dont need it disable it.you could delete it and itll reinstall when you restart and maybe find different resourses auto.if it is instaling generic driver goto hp drivers and download correct driver.
