(1) flip the Notebook/Laptop PC over - see Fig.1 below
(2) find the memory cover - it really easy to find in this photo.



Fig.1 Toshiba M35X bottom view - the memory cover is seen at center left and secured by a single screw.

(3) remove the (1) screw securing the memory cover.



Fig. 2 Toshiba M35X laptop shown with memory cover removed and HDD (Hard Disk Drive) removed, and with the HDD cover flipped up.
The RAM (SO-DIMM boards) are visible at center left.
The HDD cover is seen at the bottom of the photo.

(4) Using proper anti-static/static control techniques, clip alligator clip or your anti-static wrist strap to a frame ground of the laptop at an I/O connector or frame ground under the HDD cover.
(5) carefully remove (2) old 256 MB SO-DIMM DDR333 memory modules.
Store old memory boards in the anti-static plastic baggie in which the new memory boards were shipped.
(6) install (2) new 1GB SO-DIMM DDR333 boards, for total of 2GB of system RAM.
(7) reassemble system, and boot OS (operating system).
The laptop's ROM BIOS will auto-detect the new RAM and begin a standard POST (Power-On Self Test).
(8) If OS is MSWindows, it will also auto-detect the new memory, and allocate it to application software.

The technology of the Toshiba Satellite M35X-S349 memory module is called
DDR333, meaning DDR (Double Data Rate) SDRAM (Synchronous Dynamic RAM), at a memory bus speed of 333 MHz.
The Form Factor of the DDR memory card is SO-DIMM, which stands for Small Outline DIMM (Dual In-line Memory Module) (see photo).

Fig.3 Each 1GB SO-DIMM DDR333 memory module will look like this one.
The Toshiba Satellite M35X-S349 supports a maximum of two SO-DIMM memory modules.

Each memory module can hold (a) 256MB, (b) 512MB, or (c) 1GB,
in the SO-DIMM Form Factor compatible with the Toshiba M35X-S349 Notebook PC.

If screen is totally off (black because of it's off) - screen is dead. If it's black, but you see it's working - could be hard drive or memory fail.

The key is on the underside if your laptop. In the Microsoft label.

check battery power. Lots of times laptops won't boot if the battery has gone down to low. Probably has just enough charge to turn the machine on but not enough charge to boot the machine.

either the hard drive has failed or you are experiencing software corruption of your windows files.run the recovery or if you need information from that drive get a new hard drive install it run the recovery and use an external usb ide-sata converter to transfer your files

Please try re installing your operating system. (Genuine windows xp or vista recommended)

Hey i just read your post and i have the same proble with my laptop did you find any solution for the problem

Update: I looked at the plug connecting the HD to the PC and pulled it about 1/2 way back off and reinserted into machine. I then pulled the HD back out and noticed that it was not all the way pushed back on and it wasnt parallel to the HD. Basically I am thinking that the HD is not sitting properly in the bay for some reason or another, but I have been running 10+ hours with no problems as of yet. I did reformat the HD so I am going down that road of reloading and letting run awhile, reboot, repeat. Not sure if solution, but looking real good at this point.
