There are usually plastic clips holding the DIMM cover in place, in addition to the screws. It's okay to gently pry the cover off as long as you have removed the screws.

RAM upgrade


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

12_5_2011_7_39_30_am.jpg

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.

12_5_2011_7_42_34_am.jpg

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).

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.

Need to install memory on a veriton Z290G desktop but dont know how to open the computer


1 Turn off your computer and all the peripherals connected to it before
opening it. Then unplug all cables from the power outlets.

2 Place your computer on a flat, steady surface. If your computer is in the

vertical position, rotate the plastic stabilizers and lay your computer on its

side.

3 Turn the screws counterclockwise to release the cover.

4 Hold the sides of the cover with both hands.
5 Slide it back about an inch and then gently lift it upward to detach it.

6 Remove the side panel.

7 Locate the memory DIMM socket on the mainboard.

8 Press the holding clips on both sides of the memory DIMM socket outward

to release the memory DIMM (a). Gently pull the memory DIMM out of the
socket (b).

9 Align the memory DIMM with the socket. Press the memory DIMM into
the socket until the clips lock onto the memory DIMM.

The memory DIMM sockets are slotted to ensure proper

installation. If you insert a memory DIMM but it does not fit easily

into the socket, turn the memory DIMM around and try to insert it
again.

10 Align the cover's hinges to the housing frame; then gently push it in to

slide it back into place.
11 Secure the cover with the screws.

Help me immediately, please


Actually, the "kit" is a DIMM that plugs into the controller on the right side of the copier (when looking at it from the back of copier) On this model, you need to add 64mb of RAM if you want to add functionality to print and scan, along with the DIMM. Yes, there are 2 different DIMM's for this,....one is Print and one is Print/Scan.
PS: there is a kit to install said items that includes buttons for the controll panel and DIMM, however, the memory is separate (laptop memory or SO DIMM)
