The BIOS flash memory update is required for the following conditions:
•New versions of system programs
•New features or options
•Restore a BIOS when it becomes corrupted. 
Use the Phlash utility to update the system BIOS flash ROM.
NOTE: If you do not have a crisis recovery diskette at hand, then you should create a Crisis Recovery 
Diskette before you use the Phlash utility.
NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Phlash.
NOTE: Please use the AC adaptor power supply when you run the Phlash utility. If the battery pack does not 
contain enough power to finish BIOS flash, you may not boot the system because the BIOS is not 
completely loaded. 
Fellow the steps below to run the Phlash.
1.Prepare a bootable diskette.
2.Copy the flash utilities to the bootable diskette.
3.Then boot the system from the bootable diskette. The flash utility has auto-execution function.

1.Turn off the power to the system and all peripherals.
2.Unplug the AC adapter and all power and signal cables from the system. 
3.Place the system on a flat, stable surface. 
4.Remove the battery pack.
Disassembly Process
The disassembly process is divided into the following stages:
•External module disassembly
•Main unit disassembly
•LCD module disassembly
The flowcharts provided in the succeeding disassembly sections illustrate the entire disassembly sequence. 
Observe the order of the sequence to avoid damage to any of the hardware components. For example, if you 
want to remove the mainboard, you must first remove the keyboard, then disassemble the inside assembly 
frame in that order.
