Acer Extensa 510 Maintenance Manual

							c
Caution: If the notebook is powered up with the LCD bezel removed,
you can be exposed to high voltages which could result in shock and
equipment damage. Ensure that the batteries and AC adapter are re-
moved from the notebook when working on the LCD/Display assembly.
1.Use a narrow piece of plastic or pointed tweezers to apply light 
pressure to one edge of the lower screw covers. The lower screw
covers will bow outward and can be removed.
2.Remove the rubber upper screw covers using a pair of tweezers.
3.Remove the six screws that secure the bezel to the display assembly (a
small Phillips-head screwdriver is recommended for removing the two
screws at the top of the bezel).
4.Pull on the inside edges of the bezel; remove bezel and lay aside for 
later reinstallation.
5.Peel back the EMI shield along the right side of the display to expose 
the Inverter Board and the Contrast Board.
6.Disconnect the connectors at the top and bottom of the Inverter Board
and/or Contrast Board.
7.Use the small Phillips-head screwdriver to remove the two screws
holding the Inverter Board or Contrast Board; remove the Board
Assembly.
8.Reinstallation of the Inverter or Contrast Board is the reverse of Steps 
1 through 7 above.
6.5.10Removing/Replacing the Touchpad Assembly
To remove and replace the Touchpad Assembly, perform the following
procedure:
1. Remove the Upper Case Assembly as described in Paragraph 6.5.4.
2.Turn the Upper Case Assembly over and remove the four screws that
secure a metal shield to the plastics.
3.Lift the plastic frame that rests on top of the touchpad.
4.Unplug the flex cable from the connector on the touchpad. Note that 
the board connector is a LIF (Low insertion force) type; the cable is
held in place by friction.
5.  Slide the board assembly to the right and remove from the unit.
6.Replacement of the Touchpad Board Assembly is essentially the 
reverse of Steps 1 through 5 above.

							6.5.11Removing/Replacing the Smart Battery Board
Control Board
To remove and replace the Smart Battery Control Board, perform the
following procedure:
1.Remove the Upper Case Assembly as described in Paragraph 6.5.4. 
2.Disconnect the battery cable located next to HDD Connector.
3.Remove the two screws that secure the board to the plastics and 
remove the board.
4.Replacement is essentially the reverse of steps 1 through 3 above. 
Note:
  When reinstalling the Smart Battery Control Board, use the battery
pack as a guide to ensure that the connector slots properly align with the
battery slots.
6.5.12Removing/Replacing the Charger/Power
Supply Board Assembly
To remove and replace the Charger/Power Supply Board Assembly, perform
the following procedure:
1.Remove the Top Case Assembly as described in Paragraph 6.5.4.
2.Remove the Floppy Drive Assembly as described in Paragraph 6.5.5.
3.Using a plastic stick, lift up on the end of the board that is adjacent to
the processor. The board assembly snaps out. Remove board from
unit.
4.Replacement is essentially the reverse of Steps 1 through 3 above.
6.5.13Removing/Replacing the Main Board
To remove and replace the Main Board Assembly, perform the following
procedure:
1.  Remove the AC Adapter, Battery Pack and any installed PCMCIA
options from the notebook.
2. Remove the keyboard assembly as described in Paragraph 6.5.2.
3.  Remove the Heat Sink as described in Paragraph 6.5.3.
4. Remove the Charger/Power Supply Board as described in Paragraph
6.5.12.
5. Disconnect all interboard cable connectors.

							6. Using a small flat blade screwdriver and apply light pressure in a
rocking motion to remove the hard drive cable connector.
7. Remove four Phillips-head screws (one on each of the four sides of the
heat sink opening) securing the board to the base assembly. Do not
remove the smaller screws which are part of the PCMCIA connector
hardware.
8.Remove the Phillips head screw at the left rear of the Main Board.
9. Lift up along the front edge of the Main Board Assembly until it clears
the hard drive cavity; then pull the board forward and out of the
plastics.
10.Refer to Paragraph 6.5.14 and transfer the CPU to the replacement
Main Board.
11.Inspect the two configuration DIP switches on the replacement board;
ensure that the settings are as described in Figure 6-5.
12.Reassembly is essentially the reverse of Steps 1 through 9 above.
6.5.14Removing/Replacing the Pentium Chip
The illustration in Figure 6-6 shows the procedure for removing/replacing
the processor from/to the processor socket on the Main Board.
1.Remove the Main Board assembly as described in Paragraph 6.5.13.
2. Insert a small flat-blade screwdriver into the rightmost opening as
shown in Figure 6-6.

PC-Doctor Diagnostics
B.1Introduction
The Extensa Series Notebooks are shipped with PC-Doctor, a powerful
diagnostics tool that can help you determine the hardware configuration of
a local or remote system, benchmark its performance, analyze the
performance of all subsystems, and perform a suite of interactive and
non-interactive tests on attached devices (such as printers, joystick devices,
VGA monitors, SCSI devices, CD-ROM drives). The test results are stored in
a log which can be printed out (by pressing F2
) or saved in a disk file (by
pressing F3
).
Features of the diagnostic program are accessed through a series of
pull-down menus and basic keyboard keys (cursor keys to move highlighted
pointer, Enter
 key to select a highlighted feature, Esc
 key to cancel a
function and move back one 
level.)
PC-Doctor is typically user friendly but if you don’t understand a feature,
context-sensitive help information is available at any time by pressing the
F1
 function key; pressing the F1
 function key twice accesses the online
Technical Reference Manual for PC-Doctor.
A powerful set of utilities within PC-Doctor (that can be run locally or
remotely) simplify the task of determining system configuration data,
allocating and using system memory, IRQ and DMA use, what device drivers
are installed, what COM and LPT ports are assigned and what ports are
available, identifying partitioning data for fixed disk drive(s), determining
the VGA setup information, reading the software interrupts/interrupt
vectors, etc.
B.2Starting PC-Doctor
PC-Doctor comes pre-installed on your Extensa Series Notebook Computer.
To run the utility, reboot your computer.
The system continues the boot process and automatically displays the
PC-Doctor Diagnostics main menu.
