TP 390,1720 - Creating a hibernation file after installing additional memory

Applicable to: World-Wide

SYMPTOM:
After changing the amount of installed memory the hibernation file or partition size needs to be increased as well.

CONFIGURATION:
ThinkPad 390 or i Series 1720 with Windows 95/98.

SOLUTION:
NOTE: Hibernation works ONLY in Windows 95 and Windows 98.

The Hibernation file can be created in one of two ways:
Method 1 is recommended because it allows you to add additional memory WITHOUT deleting everything on your hard drive.
Method 2 is NOT recommended to create the hibernation file as it gives varying results with excessively large file sizes.

Method 1.
a. Build the Hibernation Utility Diskette from diskette factory, or click here to download the file from the FTP server.
b. It is recommended that before creating a hibernation file, that the hard drive is defragmented.
c. Place the Hibernation Utility Diskette in the floppy drive and power on the system.
d. Select option number 2: Create file for hibernation.
e. Follow the prompts on the screen.
f. Remove the diskette and press the space bar to reboot.

Method 2.
a. Using the PHDISK command.
b. Restart the system in MS-DOS mode or click on Start ==> Programs ==> MS-DOS Prompt from within Windows 95/98.
c. Execute the command: c:\thinkpad\phdisk /c 134851 /f (note: this process will create a 131 MB hibernation file)

ADDITIONAL INFORMATION:
Refer to your Users Reference (Guide) page #37: "Creating the Hibernation Function" for more information.

• The create hibernation partition option is available, but is NOT recommended since it will be necessary to destroy all data when removing and creating the new partition. (Option 3 on the disk or phdisk /c 134851 /p command)
• The hibernation file is located on the root of the C: drive and is named SAVE2DSK.BIN
• The line in the Autoexec.bat file that creates the hibernation file if it is not present is:
  'if not exist c:\save2dsk.bin c:\thinkpad\phdisk /c 134851 /f c: \thinkpad\yes
• If no hibernation file is present when the above command is executed at start-up, the command will create a 131 MB hibernation file.
• When you use the Utility Disk, the file created will be 34 to 36 MB if your system memory is 32 MB.
