1. After rebooting, run Tracking Pad PS2 Mode Driver. For example, run Syn touch driver.
2. Run utility with the PS/2 mouse function and check if the mouse is working.
3. If the PS/2 mouse does not work, then click if the main board to switch board FPC is connected properly.
4. If the main board to switch board FPC is connected correctly, then check if the FFC on the touch pad PCB is connected properly.
5. If the FFC on the touch pad PCB is connected correctly, check if LS851 JP1 Pin6 = 5V are pulse. If yes, then replace switch board. If not, then go to the next step.
6. Replace the touch pad PCB.
7. If the touch pad still does not work, then replace the FPC on Track Pad PCB. After you use the touch-pad, the pointer drifts on the screen for a short time. This self-acting pointer movement will occur when a slight, steady pressure is applied to the touch-pad pointer. This symptom is not a hardware problem. No actions are necessary to be taken if the pointer movement stops in a short period of time.

REMOVE KEYBOARD – ACER ASPIRE 7000 – 9300 – 7510 TravelMate _
Password Bypassing & BIOS Recovery
For RD and CSD to debug easily, AS7000/9300 &TM7510provides one hardware PIN pad for bypassing Password Check, and one Hotkey to enable BIOS Recovery.
1. PIN pad: To short PIN pad to bypass password check.
2. Hotkey to enable BIOS Recovery: Fn+ESC, then Power Button, AC+DC coexistence is strongly recommended.
Bypassing Password Check :: If the user has set Password ( power-on or setup password) for security reason, BIOS will check password during POST or when entering the BIOS setup menu. However, if it is necessary to ignore the password check, the user may enable short PIN Pad to bypass password check.
BIOS Recovery :: Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS initialization. The user can enable this feature to restore the BIOS to a successful one if previous BIOS flashing process fails.
PIN pad Location :: AS7000/9300 & TM7510 provides one hardware Pin pad under the keyboard. RD/CSD can enable this function by shorting this pad. The Pin Pad location should look as the figure.
PIN Pad :: Bypassing Password Check, Keep shorting G3 (2 triangle pad) as above PIN pad and then powering on the system will force the BIOS to clear Supervisor and User passwords. That means both the power-on and setup passwords are all cleared.
HDD password clean: It uses on DOS environment. To decode HDD password error code for unlock hard disk.
A\> unlock6 XXXX 00
XXXX -HDD password error code
Unlock6.exe v1.1 2 May 2003
Choice what kind of the password to be generated:
0) Exit
1) Scan code
2) Upper case ASCII Code
3) Lower case ASCII Code
Enter your choice 2 <- chose 2
XXXXXX
XXXXXX
XXXXXX
Those passwords are master password.
Restore BIOS by the Crisis Disk
Enter this function by Fn+ESC, and Power Button. To use this function, it is strongly recommended to have the coexistence of AC and Batter powers. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called Bootblock. RD/CSD can use this special BIOS code to recover the BIOS to a successful one if previous BIOS flashing process fails. However, before doing this, one Crisis Disk should be prepared in WinXP. Detailed steps are as the followings,
1 Prepare the Crisis Disk in WinXP (Crisis Disk will be released when BIOS V1.00 is released)
2 Insert the Crisis Disk to a USB floppy drive which is attached to the failed machine.
3 On the power-off state, press Fn+ESC and press button. The system should be powered on with Crisis Recovery process.
4 BootBlock BIOS starts to restore the failed BIOS code. Short beeps should be heard when flashing.
5 If the flashing process is finished, a long beep should be heard.
# Power down the system when Step 3.5 is finished.
If the crisis recovery process is finished, the system should be powered on with successful BIOS.
RD/CSD can then update the BIOS to a workable on by regular BIOS flashing process.
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 problems, follow the procedures below
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.

* Remove the seven outer case screws on the left (2), bottom (3), and right (2) side of the camera.
* Pry open the case from its bottom left side. There will be a little resistance. Just use a butter knife at the bottom left (screen side) edge to pry it open. Note how/where the AV cover attaches to the case.* Remove the single small screw on the silver lanyard connector.
* Loosen the center electronics assembly from the front case by prying with a small screwdriver along the gray plastic on the left side of the camera.
* Remove the center electronics assembly from the front case by lifting it up and out from its bottom.
Note the front face with the battery compartment, lens assembly (note that mine is crooked/damaged), auto-focus illuminator, and flash assembly. Especially take note of the large green flash capacitor. DO NOT short the terminals of the capacitor to discharge it as you will damage it. Instead recommend slowly draining the capacitor of electricity by applying a voltmeter or some other resistive load until its voltage is discharged.
Now examine the top face of the assembly. Note the tape, and the three exposed screws. Remove and temporarily store these three screws.
* Peel back the center portion of the tape. You may have to tear a portion of the tape. You'll see two electrical contact points labeled C4+ and C4-. Use these to discharge the capacitor. You'll also notice a single screw that attaches the flash bulb to the camera. Leave this screw alone as it is unrelated to the disassembly of the camera. Reattach the tape.
