Safety information The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer. General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
Electrical safety Observe the following rules when working on electrical equipment. Important Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges.
This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide. If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.
Insulation must not be frayed or worn. 4. Remove the cover. 5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations. 6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.
Laser compliance statement Some IBM Personal Computer models are equipped from the factory with an optical storage device; such as a CD-ROM drive or DVD-ROM drive. They are also sold separately as options.

Supervisor password: A supervisor password (SVP) protects the system information stored in the IBM BIOS Setup Utility. The SVP must be entered in order to get access to the IBM BIOS Setup Utility and make changes to system configuration settings.
(B) If an SVP has been set and is known by the servicer: 1. Turn on the computer by pressing and holding F1. 2. Enter the SVP. The IBM BIOS Setup Utility menu appears. 3. Select Password, using the cursor keys to move down the menu.
Screen blank mode has three variants, as follows: 1. If you press Fn + F3, or the time set on the “LCD off timer” in IBM BIOS Setup Utility expires, v The LCD backlight turns off. v The hard-disk drive motor stops.
v If the battery indicator blinks orange, indicating that the battery power is low. (Alternatively, if Hibernate when battery becomes low has been selected in the “Power Management Properties” window, the computer goes into hibernation mode.) Note for the APM operating system: Even if you do not set the low-battery alarm, the charge indicator notifies you when the battery is low, and then the computer enters the power-saving mode automatically.
Page 38
When the power is turned on, the computer returns from hibernation mode and resumes operation. The hibernation file in the boot record on the hard-disk drive is read, and system status is restored from the hard-disk drive. ThinkPad A20m/p, A21m/p, A22m/p Related service information...
