How to upgrade the Ram Memory of a Toshiba Satellite M35X-S114 Notebook PC, and stating special precautions at the same time:
1) Work on a table. Do Not work on a bed, couch, or directly on a carpet floor.
These are high areas of Static electricity.
[ Static electricity can fry out (Short Circuit) the hardware components inside your computer. It can also fry out the new Ram Memory module/s before you install them ]
Do Not remove the new Ram Memory module/s from their protective Anti-Static cartons, or boxes, until you are ready to install them. (Old ram memory module/s removed)
If you do not have an ESD wrist strap available, and a good ground source to connect the alligator clip to, at least touch a metal door knob before sitting down to replace the Ram Memory.
If your table is sitting on a carpet floor, refrain from swinging your legs, and your feet on the carpet.
2) Remove ALL power to the laptop.
Remove the AC adapter (Charger) and Battery.
Press the Power On button, and hold it down for a count of 5 seconds. Let go. Do this procedure two more times. You are draining any residual power.
3) Laptop turned over the Memory Compartment Cover is the small square cover.http://www.irisvista.com/tech/laptops/ToshibaM35X/satM35X_1.htm
Left-click on the photo in Step 1.
Now close this small window, and left-click on the photo in Step 2.
Step 1 photo shows you the Memory Compartment Cover, and the single Philips head screw to remove.
Step 2 photo shows the Memory Compartment Cover removed, and the Ram Memory modules locked into the ram memory slots.
The Ram Memory modules ('Sticks') are DIMM modules. Dual Inline Memory Module.
They are a variation also for a laptop. They are SO-DIMM.
Small Outline Dual Inline Memory Module.
There are 200 gold plated contact pins on the bottom of the ram memory module.
100 on EACH side.http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png
The photo above is to show a typical example of a SO-DIMM ram memory module.
I would like you to;
A) Observe the gold plated contact pins on the bottom.
B) Observe the Locating Notch in the bottom of the ram memory module.
C) Observe the Notch on each side of the ram memory module.
D) Observe the Black DRAM chips on the side of the ram memory module
When handling a Ram Memory module, refrain from touching the gold plated contact pins on the bottom.
Handle the Ram Memory module by the body of the module.
This area is where the black DRAM chips are.
The body is coated with a see-through protective plastic.
Note the Locating Notch in the bottom, and how it is not centered.
This Locating Notch MUST line up with a Locating Lug, in the bottom of the Ram Memory slot.
Observe the direction the old ram memory module comes out.
There are metal clips on each side of a ram memory slot, that hold the ram memory module in place.
These metal clips are Locks.
Thin spring steel clips with a protrusion, or 'Bump' on the end.
The protrusion, or 'Bump' snaps into the Notch on the side of the Ram Memory module.
One on either side.
To remove the Ram Memory modules, if there are more than one, you have to remove the top one first.
Take your fingernails, and gently spread the metal Lock clips, towards the outside of the Ram Memory module
Sometimes when you ease the metal clip out on one side, that side will pop up a little bit.
Sometimes it takes releasing both Lock clips at the Same Time.
When the 'Bumps' are free from the Notches on the side of the Ram Memory module, the Ram Memory module will spring up, or pop up, a little bit.
Hold onto the upper corners with your fingertips, and slide the Ram Memory module out.
DO NOT pick straight up on a Ram Memory module when removing!
You will bend the contact pins of the ram memory module, and ruin the contact pins down in the ram memory slot.
The Ram Memory module comes out at an angle.
Install the bottom Ram Memory module first. (Yeah I know. Duh!)
Line the Locating Notch up with the Locating Lug.
Slide the Ram Memory module into place until the spring Lock clips need to be spread.
Spread the clips, slide the Ram Memory module all the way into place.
Be SURE the metal Lock clip 'Bumps' are seated into the Notches on the sides of the Ram Memory module.
This way you can be assured that the Ram Memory module is seated correctly.
Reinstall the Memory Compartment Cover.
Turn the laptop over, reinstall the Battery FIRST.
Then plug the AC adapter in.
WAIT 20 seconds, turn the laptop on.
BIOS will automatically 'recognize' the new ram memory.
