Here’s how you can replace or upgrade memory (RAM) in a Toshiba Portege M400 Tablet PC.
The Official Dynabook & Toshiba Support Website provides support for Portege M400. And its subsidiaries were deconsolidated from Toshiba Group on October 1, 2018. Look under Windows edition for the version and edition of Windows that your PC is running. Laptops Troubleshooting. May 09, 2009 Hi, I have a toshiba portege m400. It has windows xp proffessional SP3 installed (the previous owner replaced it with this from the xp tablet edition - i want to upgrade to vista so i can have the tablet abilities back!) Anyway, I've got a version of vista - a home premium upgrade version.
As you see on the picture below, there is no access to the RAM slots on the bottom.
Why? Because both RAM slots are hidden under the keyboard.
According to manufacturer specifications a Toshiba Portege M400 Tablet PC can handle up to 4GB memory total.
That means you can install up to 2GB module into each slot.
Now remove two screws and release a small plastic latch in the middle.
Lift up the keyboard as it show on the picture and place it upside down on the palm rest.
You’ll find two covers under the keyboard.
Install Windows 7 Toshiba Portege M400 Manual
Both memory modules are hidden under the right cover. Remove two screws and remove the cover.
In my case both RAM slots are occupied with 512MB modules.
I’m going to remove both modules and replace them with new once.
Spread latches on both sides with thumbs.
The RAM module will pop up at a 30 degree angle.
Carefully pull the module by the edges and replace it with a new one.

Hi, I am trying to install Windows 7 ultimate on my Toshiba Portege M400 and having issues. It is currently running Windows XP tablet edition. I start the installation and I first: 1. Go online to get the latest updates for installation 2. I click custom installation. (not upgrade) 3. It ask me where I want to install windows and my Disk drive: DISK 0 PARTITION 1: TABLET-OS(C shows up. I try to click on it and can't click next. There is a message at the bottom that I click on that states: 'Windows cannot be installed to this disk. Windows needs the driver for device [Toshiba RAID]. Click load driver and load the required device driver. 4. I click load driver and browse to driver that I have downloaded: drivers I have downloaded: util_hdd_protection, util_raid_virtual_device, driver_raid_TC00170000B.EXE 5. I get the message 'no device driver were found. Make sure that the installation media contains the correct drivers, and the click ok. 6. I can't get passed this point. I have downloaded every driver on Toshiba's website that has to do with HDD or raid drivers. It looks like all the device drivers that I am downloading are .exe files and not the actually driver. I have called Toshiba and the are useless. Please help!!! THANKS BOBBY
