Chapter 2 System Utilities BIOS (Basic Input and Output System) includes a CMOS SETUP utility which allows user to configure required setting or to active certain system features. The CMOS SETUP saves the configuration in the CMOS SRAM of the mainboard. When the power is turned off, the battery on the mainboard supplies the necessary power to the CMOS SRAM. When the power is turned on, pushing the button during the BIOS POST (Power-On Self Test) will take you to the CMOS SETUP screen.
Entering Setup Once enter Award BIOS CMOS Setup Utility, the Main Menu (as figure below) will appear on the screen. Use arrow keys to select among the items and press to accept or enter the sub-menu. Note: If you can’t find the setting you want, please press “Alt+F4” to search the advanced option hidden.

Chapter 4 Troubleshooting This chapter provides troubleshooting information for the Aspire L100 Chapter 4 q Power-On Self-Test (POST) q Index of Error Message q Index of Error Symptoms q Undetermined Problems 57
Power-On Self-Test (POST) Each time you turn on the system, the Power-on Self Test (POST) is initiated. Several items are tested during POST, but is for the most part transparent to the user. The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the system components, and controls the operation of the power-on password option.

Auto detect ports for keyboard & mouse followed by a port & interface swap (optional). 3.
. Checkpoint 60 Description 23h 1. Check validity of RTC value: e.g. a value of 5Ah is an invalid value for RTC minute. 2. Load CMOS settings into BIOS stack. If CMOS checksum fails, use default value instead. 3. Prepare BIOS resource map for PCI & PnP use. If ESCD is valid, take into consideration of the ESCD’s legacy information. 4. Onboard clock generator initialization. Disable respective clock resource to empty PCI & DIMM slots. 5.

POST Error Messages List If you cannot run the diagnostics program tests but did receive a POST error message, use “POST Error Messages List” to diagnose system problems. If you did not receive any error message, look for a description of your error symptoms in “Error Symptoms List” on page 66. NOTE: When you have deemed it necessary to replace an FRU, and have done so, you must run a total system check to ensure that no other activity has been affected by the change.
BIOS Messages Action/FRU Keyboard Error Or No Keyboard Present Cannot initialize the keyboard. Make sure the keyboard is attached correctly and no keys are pressed during POST. To purposely configure the system without a keyboard, set the error halt condition in Setup to HALT ON ALL, BUT KEYBOARD. The BIOS then ignores the missing keyboard during POST. Keyboard is locked out - Unlock the key This message usually indicates that one or more keys have been pressed during the keyboard tests.
Error Symptoms List NOTE: To diagnose a problem, first find the error symptom in the left column. If directed to a check procedure, replace the FRU indicated in the check procedure. If no check procedure is indicated, the first Action/ FRU listed in right column is the most likely cause.
Error Symptom Action/FRU Diskette drive read/write error. 1. 2. 3. 4. Diskette. Diskette drive cable. Diskette drive. Main board. Diskette drive LED comes on for more than 2 minutes when reading data. 1. 2. 3. 4.

Error Symptom Action/FRU CD/DVD-ROM drive does not read and there are no messages are displayed. 1. CD may have dirt or foreign material on it. Check with a known good disc. 2. Ensure the CD/DVD-ROM driver is installed properly. 3. CD/DVD-ROM drive. CD/DVD-ROM drive can play audio CD but no sound output. 1. Ensure the headphone jack of the CD/DVD-ROM has an output. 2. Turn up the sound volume. 3. Speaker power/connection/cable. 4. CD/DVD-ROM drive. Real-Time Clock Real-time clock is inaccurate. 1.
Error Symptom Display problem not listed above (including blank or illegible monitor). Chapter 4 Action/FRU 1. “Monitor" 2. Load default settings (if screen is readable). 3.
Error Symptom Action/FRU Parallel/Serial Ports Execute “Load BIOS Default Settings” in BIOS Setup to confirm ports presence before diagnosing any parallel/serial ports problems. Serial or parallel port loop-back test failed. 1. Make sure that the LPT# or COM# you test is the same as the setting in BIOS Setup. 2. Loop-back. 3. Main board. Printing failed. 1. Ensure the printer driver is properly installed. Refer to the printer service manual. 2. Printer. 3. Printer cable. 4. Main board.
Undetermined Problems If an error message is present, go to “POST Error Messages List” on page 64. If you did not receive any messages, if the symptom is listed in “or “Error Symptoms List” on page 66. If you still cannot solve the problem, continue with this check: 1. Check the power supply voltages. If the voltages are correct continue with the following steps: 2. Power off the system unit. 3. Perform the following checks, one by one, until you have isolated the problem FRU. 4.
