Chapter 3165 Clearing Password Check and BIOS Recovery This section provide you the standard operating procedures of clearing password and BIOS recovery for Aspire 5739. Aspire 5739 provides 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 a BIOS Password (Supervisor Password and/or User Password) for security reasons, the BIOS will prompt for a password during system POST or when systems enter to BIOS Setup menu. However, if it is necessary to bypass the password check, users need to short the HW Gap to clear the password by performing the following procedure: 1.Power off the system, and unplug the AC and Battery from the machine. 2.Open the Hard Drive and RAM doors. 3.Remove the Hard drive. 4.Find the appropriate HW Gap on M/B as shown in the picture. •G1 is the RTC Reset. When asserted, this signal resets register bits in the RTC well. Unless the CMOS is being cleared (only to be done in the G3 power state), the RTCRST# input must always be high when all other RTC power planes are on. In the case where the RTC Battery is dead or missing on the platform, the RTCRST# pin must rise before the RSMRST# pin. •G2 is the Secondary RTC Reset. This signal resets the manageablility register bits in the RTC well when the TRTC battery is removed. The SRTCRST# input must always be high when all other RTC power planes are on. In the case where the RTC Battery is dead or missing on the platform, the SRTCRST# pin must rise before the RSMRST# pin. 5.Use an electric conductivity tool to short the two points of the desired HW Gap. 6.Plug in AC, keeping the HW Gap shorted, and press Power Button to power on the system till BIOS POST finish. Then remove the tool from the HW Gap. ItemDescriptionLocation G1/G2 Clear CMOS Jumper Adjacent to RTC Battery
166Chapter 3 7.Restart system. Press F2 key to enter BIOS Setup menu. If there is no Password request, the BIOS Password has been successfully cleared. Otherwise, please follow the steps and try again. NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).
Chapter 3167 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.
Chapter 6169 FRU (Field Replaceable Unit) List This chapter gives you the FRU (Field Replaceable Unit) listing in global configurations of the Aspire 5739. Refer to this chapter whenever ordering for parts to repair or for RMA (Return Merchandise Authorization). Please note that WHEN ORDERING FRU PARTS, you should check the most up-to-date information available on your regional web or channel. For whatever reasons a part number change is made, it will not be noted on the printed Service Guide. For ACER AUTHORIZED SERVICE PROVIDERS, your Acer office may have a DIFFERENT part number code from those given in the FRU list of this printed Service Guide. You MUST use the local FRU list provided by your regional Acer office to order FRU parts for repair and service of customer machines. NOTE: To scrap or to return the defective parts, you should follow the local government ordinance or regulations on how to dispose it properly, or follow the rules set by your regional Acer office on how to return it.
