Intermittent Problems
Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a 
hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement 
should be considered only when a recurring problem exists.
When analyzing an intermittent problem, do the following:
1.Run the advanced diagnostic test for the system board in loop mode at least 10 times.
2.If no error is detected, do not replace any FRU.
3.If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors. 
Undetermined Problems
The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, 
whether a short circuit is suspected, or whether the system is inoperative. 
Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU).
NOTE: Verify that all attached devices are supported by the computer.
NOTE: Verify that the power supply being used at the time of the failure is operating correctly. (See “Power On 
Issue” on page 124.):
1.Power-off the computer.
2.Visually check them for damage. If any problems are found, replace the FRU.
3.Remove or disconnect all of the following devices:
•Non-Acer devices
•Printer, mouse, and other external devices
•Battery pack
•Hard disk drive
•DIMM 
•CD-ROM/Diskette drive Module
•PC Cards
4.Power-on the computer.
5.Determine if the problem has changed.
6.If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU.
7.If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU:
•System board
•LCD assembly

Clearing Password Check and BIOS Recovery
This section provide you the standard operating procedures of clearing password and BIOS recovery for 
TravelMate 4730/4730G. TravelMate 4730/4730G provide one Hardware Open Gap on main board for 
clearing password check, and one  Hotkey  for enabling BIOS Recovery.
Clearing Password Check
Hardware Open Gap Description
Steps for Clearing BIOS Password Check
If users set BIOS Password (Supervisor Password and/or  User Password) for a security reason, BIOS will ask 
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is 
necessary to bypass the password check, users need to short the HW Gap to clear the password by the 
following steps:
•Power Off a system, and remove HDD,  AC and Battery from the machine.
•Open the back cover of the machine, and  find out the HW Gap on M/B as picture.
•Use an electric conductivity tool to short the two points of the HW Gap.
•Plug in AC, keep the short condition on the HW  Gap, and press Power Button to power on the 
system till BIOS POST finish. Then re move the tool from the HW Gap.
•Restart system. Press F2 key to enter BIOS Setup menu.
•If there is no Password request, BIOS Password is  cleared. Otherwise, please follow the steps and 
try again.
NOTE:  The steps are only for clearing BIOS Password  (Supervisor Password and User Password).

BIOS Recovery by Crisis Disk
BIOS Recovery Boot Block:
BIOS Recovery Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS 
initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous 
BIOS flashing process failed.
BIOS Recovery Hotkey:
The system provides a function hotkey: Fn+Esc, for enable BIOS Recovery process when system is powered 
on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery 
present. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called Boot 
Block.
Steps for BIOS Recovery by Crisis Disk:
Before doing this, one Crisis Disk should be prepared ready in hand. The Crisis Disk could be made by 
executing the Crisis Disk program in another system with Windows XP OS.
Follow the steps below:
1.Power Off failed system.
2.Attach a USB floppy drive to the failed system. 
3.Insert the Crisis Disk in to the USB floppy drive attached to the BIOS flash failed system.
4.In the power-off state, press and hold Fn+Esc then press the Power button. 
The system powers on and the Crisis BIOS Recovery process begins.
BIOS Boot Block begins restoring the BIOS code from the Crisis floppy disk to BIOS ROM on the failed 
systems.
When the Crisis flash process is finished, the system restarts with a workable BIOS. 
5.Update to the latest version BIOS for the system using the regular BIOS flashing process.
