Service and Maintain

After replacing the system board, make sure the display panel manufacturer setting is correct in BIOS. If
the incorrect panel manufacturer is set in BIOS, the display panel may function incorrectly.
The display panel manufacturer is identified on the jumper setting label on the base pan.
After confirming the manufacturer of the display panel on the computer, go into BIOS and make sure
the LVDS Panel Select setting is correct.
To update BIOS with display panel model information:
1. Boot the computer.
2. Repeatedly press F10 when the monitor light turns green to access the F10 Setup utility.
3. Select Advanced, select Device Options, select LVDS Panel Select, and then select the
manufacturer for the new display panel.
4. Save your settings, exit F10 Setup, and allow the computer to continue to the operating system.
When you change the LVDS setting to the installed panel type, the BIOS reprograms the EDID with the
correct data. You must set the panel before the Auto-select setting functions correctly.
Updating SMBIOS Information
When replacing the system board, you must reprogram the SMBIOS information on the affected
computer. Failure to reprogram the board will result in eventual failure, such as an activation failure
(need to reactivate the system) or a system recovery failure.
To update SMBIOS information in Computer Setup:
1. Turn on or restart the computer.
2. Press Esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of
the screen.
NOTE: If you do not press Esc at the appropriate time, you must restart the computer and again
press Esc when the monitor light turns green to access the utility.
3. Press F10 to enter Computer Setup.
4. Go to Security > System ID’s.
5. If necessary, press Ctrl+A to initiate edit mode.
6. Edit the fields listed. If the feature byte has data or is not editable, then it was not cleared and
cannot be edited.
