System Internal Inspection

1.Turn off the power to the computer and all peripherals.

2.Unplug the power cord from the computer.

3.Unplug the network cable and all connected peripheral devices from the computer.

4.Place the computer on a flat, steady surface.

5.Remove the side panel as described in page 15.

6.Verify that the SSD module and the RTC battery are properly seated.

7.Remove the mainboard as described in page 21.

8.Verify that memory module(s) are properly seated.

9.Verify that all components are Acer-qualified and supported.

10.Reinstall the mainboard.

11.Reinstall the side panel.

12.Power on the system.

If the cause of the failure is still can not be determined, review the POST messages and BIOS checkpoints during the system startup.

Checkpoints

A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoints during bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoints are very useful in aiding software developers or technicians in debugging problems that occur during the pre-boot process.

Viewing BIOS Checkpoints

Viewing all checkpoints generated by the BIOS requires a checkpoint card, also referred to as a POST card or POST diagnostic card. These are ISA or PCI add-in cards that show the value of I/O port 80h on a LED display. Checkpoints may appear on the bottom right corner of the screen during POST. This display method is limited, since it only displays checkpoints that occur after the video card has been activated.

NOTE: Please note that checkpoints may differ between different platforms based on system configuration. Checkpoints may change due to vendor requirements, system chipset or option ROMs from add-in PCI devices.

UEFI BIOS POST Code Checkpoints

The UEFI BIOS POST Code sets up the chipset, memory, and other components before system memory is available. The following table describes the type of checkpoints that may occur during the boot block

initialization portion of the BIOS.
