When you turn on the computer with OS/ 2 Warp installed, make sure no
compact disc (CD) is in the CD-ROM drive.
Some CDs cause the computer to lock up and accept no input when the
computer is turned on with the CD installed. If the computer locks up with
the CD installed in the CD-ROM drive, remove the CD, turn off the
computer, and turn the computer on again.
To turn the computer off, press the Power Shutdown switch on the rear of
the computer with the tip of a pen to turn off the computer; then turn the
computer on again.
The computer enters suspend mode automatically when the processor
temperature is higher than a certain degree. This is not a defect.
Processor speed may decrease if the computer is used under the following
conditions, for thermal protection. This is not a defect.
The computer is used in a high-temperature environment. (See
Appendix C.)
The computer is getting hot because it is maintaining operations that require
high power consumption for a long time.
Have the computer serviced.
If the suspend lamp is turned on, connect the AC Adapter or install a fully
charged battery pack in the computer; then resume operations.
If there is still a problem, press the Power Shutdown switch on the rear of the
computer with the tip of a pen to turn off the computer.
Check that the startup sequence in Easy-Setup is set to start the computer from
the diskette drive (see page 38).
Check that:
A Kensington lock or compatible lock is not in use.
The security latch at the right side of the computer is unlocked. (See step 2
on page 7.)
Note: Slide the keyboard latches toward the front to open the keyboard.
