Question about Lenovo T7200 Notebook

Removed 1gb memeory and installed 2gb but only 2gb recognized

I have a Toshiba p205 6287 laptop with 2gb of memory. I removed 1gb and installed a 2gb memory module in its place. When I booted up my machine still only recognizes 2gb of memory, instead of 3gb. I am running vista home version. I've re-seated the memory twice and it seems ok. Since it still thinks I have 2gb, it must recognize at least 1gb of the new memory. Anybody have any ideas on this? Thanks in advance...

You may need to go to your manufacturer's website for toshiba, and flash your bios with the latest flash for this.

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).
Reference: http://en.wikipedia.org/wiki/DDR_SDRAM

12_5_2011_8_13_41_am.jpg

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.

I have a toshiba satellite A135-S4467 laptop, using two memory slots, totaling 1G. I've bought a Kingston ValueRAM - 2GB PC2-6400 DDR2 Laptop Memory Module. What is the best way to install my new 2G...


Hi, Yes, it would be best to take the old RAM out. I am assuming that this is 1 stick totalling 2GB. Optimally it would be good to have 2 x 1GB modules totaling 2GB, so they could work together. Otherwise, yes, just remove the the old ram and install the new module. If you are running a 32bit operating system, 3GB is all the system can use anyway. Hope this helps!

I've installed 2 gigs of ram and it won't recognize the second stick.


The L25 series laptops can take a maximum of 2GB of memory, 1GB per slot. It should be DD2 PC-5300 spec RAM. Below is some specifications the memory should meet alongst with a compatible part number.
Part #: CT540972 • DDR2 PC2-5300 • CL=5 • Unbuffered • NON-ECC • DDR2-667 • 1.8V • 128Meg x 64

2G memory card not working


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.

I have a new Toshiba NB205 netbook and I want to replace the memory card with a Crucial 2GB card. I removed the back panel (1 small Phillips screw) and I see the 1GB card, but I do not know how to remove...


Steps to perform it.
1. remove the battery pack from your laptop
2. In perfect case you would need ground wire put on you hands.
3. move latches from each side of the memory to side.
4.then it should move up remove it.
5. Install new memory

Can I upgrade memory to only one gb of memory or install 2 512 mb on a toshiba satellite m35x series


http://www.shopping.com/xPF-Toshiba-Toshiba-Satellite-Notebook-PC-M35X-S114

Looking at the specs, the max is 2gb for your Toshiba. According to this website, its only a 256mb ddr sdram. So my guess is you only have 1 slot for the ram. I'd go with a 2gb ram if you can afford it, 1gb just don't cut it in todays technology.

I believe its the PC2700 model, so find a 1gb or 2gb PC2700 @ 333mhz and you should be set.

Not enough memory


  • your Toshiba Satellite M35X-S311 has the following memory configuration
  • Configured with 512MB
  • The maximum memory you can have is 2048MB (Max),
  • 2 memory slots using 1024MB PC2700 DDR333 SDRAM 2.5V SODIMM Memory modules (Both slots may be occupied). Go to a store and request for this memory specification and you will have 2GB of memory for all the programs you have listed here. Good Luck!

I have a Toshiba Tecra M2 Laptop. I just installed (2) 1gb ram chips. Bios only shows 1.256 Windows only shows 1.256 Where or how do I access or show 2gb RAM>


This could be bad memory or possibly (but unlikely) a bad memory controller. To test this remove one stick and power it on and look at the size, than switch the pieces of memory and check that one. If they both show 1gb then try each stick in the other slot. If they both do not show 1 gb then there is the problem.

1024 RAM


You will need to remove the 2-512MB ram that are installed on your computer and buy 2-1GB sticks. There is no other way around this. Download CPU-Z program to find exact memory module needed before you buy the wrong one. Good luck.
