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 adapter 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. Follow 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.
Chapter 368 This chapter contains step-by-step procedures on how to disassemble the notebook computer for maintenance and troubleshooting. To disassemble the computer, you need the following tools: qWrist grounding strap and conductive mat for preventing electrostatic discharge qSmall Philips screw driver qPhilips screwdriver qPlastic flat head screw driver qTw e e z e r s NOTE: The screws for the different components vary in size. During the disassembly process, group the screws with the corresponding components to avoid mismatch when putting back the components. When you remove the stripe cover, please be careful not to scrape the cover. Chapter 3 Machine Disassembly and Replacement
69Chapter 3 General Information Before You Begin Before proceeding with the disassembly procedure, make sure that you do the following: 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.Remove the battery pack.
Chapter 370 Disassembly Procedure Flowchart The flowchart on the succeeding page gives you a graphic representation on the entire disassembly sequence and instructs you on the components that need to be removed during servicing.
