[. . . ] Also, if boot manager is installed, the computer cannot enter hibernation mode. In hibernation mode, the following occurs: The system status, RAM, VRAM, and setup data are stored on the hard disk. Events that cause the computer to enter hibernation mode: Hibernation mode requested by function key (Fn+F9). 14 ThinkPad 240 Timer conditions are satisfied in suspend mode when hibernate by timer is enabled. (BIOS Setup) The computer exits hibernation mode and resumes operation when the power-on switch is pressed. When power is turned on, the hibernation file in the boot record on the hard disk drive is read and the system status is restored from the hard disk drive. The power switch must be pressed to cause the computer to resume operation from hibernation mode. How to Create the Hibernation Function: Do as follows: Turn off the computer. Insert the hibernation utility diskette into the diskette drive (you can create the diskette using the Diskette Factory). Note: If you change the memory size, you need to recreate the hibernation file or partition. For partition-based hibernation, use the hibernation utility to delete the partition first before creating a new one. ThinkPad 240 15 Symptom-to-FRU Index The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. Note: Perform the FRU replacement or actions in the sequence shown in the FRU/Action columns. If a FRU replacement does not solve the problem, put the original part back in the computer. This index can also be used to help you decide the next possible FRUs to be replaced when servicing a computer. Numeric error codes show the errors detected in POST or system operation (runtime). If the symptom is not listed, go to "Undetermined Problems" on page 22. Note: For IBM devices not supported by diagnostic codes in this ThinkPad computer, see the manual for that device. Numeric Error Codes The following is a list of the message that the BIOS can display. Some of them display information about a hardware device, e. g. , the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. Following the list are explanations of the messages and remedies for reported problems. If the system fails after you make changes in the Setup menus, reset the computer, enter Setup and install Setup defaults or correct the error.
