MP975 Upgrades 

The following information describes how to upgrade the Memory, Hard Drive, and Microprocessor.  Note that some upgrades may be beyond the capabilities of some users to perform on their own.  If you do not feel comfortable to technically capable, do not attempt to do upgrades on your own.  You should consult our service department or another computer professional for assistance.

Disclaimer: We make our best efforts to make this technical information as accurate as possible, however we cannot guarantee that the information will be 100% accurate in all applications.  We cannot be responsible for any damages resulting from the use of this information.  Although upgrading your computer will not void your warranty any damages caused while attempting an upgrade will not be covered by our warranty. If you have any doubts, please contact our service department or another computer professional

Memory
Type 4MB,8MB,16MB,32MB 72pin, 5v, non parity, 60ns, Fast Page Mode or EDO SODIMM.  Note that systems with serial numbers beginning with "AA" can only use Fast Page Mode Memory.
Layout The system has 16MB on board with two sockets located under the keyboard.  To expand the memory, both of these sockets must be filled with identical memory modules.

Installation Instructions
  1. Turn the computer off and remove all power sources
  2. Open the LCD as far back as it will go. 
  3. There is a cover plate which houses the power button, the window to the small status icon LCD, and also covers the LCD hinges.
  4. Grasp this plate at the parts where it covers the LCD hinges (near the speakers) and lift this plate upward.
  5. Once this plate is removed, look at the tab in the upper right of the keyboard, next to the print screen key.  If there is a screw in this tab remove it.
  6. Lift the keyboard starting at the edge closest to the LCD and then stand the keyboard up against the screen.
  7. Under the keyboard you will see 2 sockets.  To install memory, insert it at a 45 degree angle and snap down flat.  Memory modules are keyed so that they can only be inserted one way.  (see diagram)
  8. Replace the keyboard and cover plate
  9. On the first boot, you will receive a memory size mismatch error.  Press Ctrl+Alt+S to enter the setup.  Once in setup, go under exit and select save and reboot.

Hard Drive
Type 2.5" x 17mm (max) EIDE

Note that some newer drive models (mostly Toshiba) require the system to have the later core logic and the latest BIOS.  If you use a drive which is not compatible, you will get a "hard disk 1" failure message during boot.  The requirements for these newer drives are the same as the requirements for year 2000 compliance.  Check the Y2K information page, if your computer is Y2K compatible, it will also be compatible to these newer drives.

Location The hard drive is located on the bottom rear of the computer.

  1. Turn the computer off and remove all power sources.
  2. Turn the computer over.  On the bottom the rear section is raised. One side has fan vents and the other is solid.  The solid side is the hard drive.
  3. Slide and hold the release latch located almost directly in the center of the bottom of the computer.
  4. While holding the latch, slide the hard drive towards the fan vents.  Once the drive slides over you can lift the drive upward and remove it.
  5. The assembly that you remove is the drive mounted inside a carrier.  There are 3 screws which hold the carrier together.  Remove these screws and remove the metal casing.
  6. The hard drive mounting has 4 main pieces.  The bottom plastic, the connector frame, the spacer plate, and the top metal case. Remove the spacer plate and unplug the cable from the hard drive.
  7. Connect the cable to the new hard drive.  The driver should have the same side up.
  8. Place the hard drive and connector frame into the bottom plastic piece.
  9. If you are using a 12.5mm high hard drive, you must place the spacer plate on top of the hard drive.  DO NOT Place the spacer plate under the hard drive as this will likely short out the drive and possibly damage the drive and the mainboard.  If you are using a 17mm hard drive, you will not use the spacer.
  10. Place the top metal case on top of the mounting. Note that the metal will go inside all molded tabs in the bottom plastic.  If you do not get this correct, you will have trouble either inserting the screws or trying to lock the assembly into the computer.  If done correctly, there should not be much tension on the screws.  If you have to crank the screws down, chances are that the assembly is not together correctly.
  11. Insert the driver assembly into the computer.
  12. Boot the computer and press CTRL+ALT+S to enter the setup.   Go under Exit and select Default Settings.  After loading defaults, select save and reboot.
  13. Boot from a DOS boot disk and run the 0vmakfil utility to create the suspend to disk (S2D) partition.  See the FAQ page for more info.
  14. Load your operating system.  See the FAQ page for drivers and loading instructions.
Microprocessor
Type Intel Pentium P54C 75~200Mhz is supported by all versions.

MMX is supported by systems with a 2.8v setting on the mainboard.  You can check this by removing the hard drive (see above) and looking at the mainboard.  On the mainboard under the hard drive, there are switch settings printed.  If there is setting printed for 2.8V, you can support MMX.  If there is no 2.8v setting, you cannot use MMX (2.9v is NOT good enough)

233Mhz is supported on systems which support MMX and also have "7" as the second digit of the serial number.

Location The microprocessor is located on the under side rear of the computer, under the door with the fan vents.
Installation Instructions
  1. Turn the computer off and remove all power sources
  2. Remove the hard drive (see above)
  3. Remove the 2 screws on the door with the fan vents
  4. Slide the door towards the center of the computer and remove lift off
  5. Under the door you will see a heatsink/fan assembly.
  6. Next to the fan there is a duct, in the center of this duct is a piece of tape which covers a screw. Peel back the tape and remove this screw.
  7. Just to the other side of the fan there is a second screw. Remove this and remove the heatsink/fan
  8. You will see the Intel Chip. It is in a white socket. You should see the 2 tabs labeled Lock and open on either side of the chip.  Look at the Lock side, it may be covered by a black plastic clip.  If this clip is there, remove it.
  9. Insert the tip of a flat screwdriver into the hole on the open side and move the handle of the screwdriver towards the chip.  This will move the socket and chip about 1mm.
  10. Remove the chip from the socket
  11. Set the switches to match your new CPU chip.
  12. Insert the new chip, it should just drop into place.   Note the pins are not symetrical, so the chip will only fit in one direction.
  13. Place a flat screwdriver into the lock side of the socket and move the handle toward the chip.
  14. You must be sure the socket moves all the way so that there is no gap on the open side (see diagram).  This often takes a bit more force than most people think they should apply.  If the socket does not lock all the way either the system will not boot or the socket will loosen causing the system not to boot at a later date.
  15. Re-assemble the computer.

Next to the CPU there are 2 switch blocks.  There is one 4 switch block labeled SW2 and one 8 switch block labeled SW1. The 4 switch block (SW2) is used to configure the LCD type, DO NOT change any of the switches on this block.  Changing these switches can damage your LCD. The 8 switch block (SW1) is used to configure your CPU.  The settings for SW1 are as follows:

Note these settings cover most versions, you should verify with the settings printed on your mainboard under the hard drive assembly.  If the settings differ, use the settings printed directly on the mainboard.

SW1:1 - This is labeled for AMD/Intel, however AMD support was abandoned prior to product release, so only Intel CPU's can be used.  You should leave this switch off.
