# ML500 Series ## Technical Resources ### Internal Access The ML500 can be opened by the user. This does not void the warranty, however, any damage caused by doing so will not be covered. 1. Ensure your body is discharged of any static electricity by touching a grounded metal surface. 2. Begin by removing the 8x Phillips case screws indicated by the green arrows.

3. Insert a flathead screwdriver into the ridge between the internal heatblock and lid. 4. Rotate the screwdriver to pop them apart. They are held together by thermal paste. Moderate force is required to pop them apart.

5. The lid can now be removed from the system. Pull the lid and system apart from one another. 6. You now have full access to the components, including the RAM and SSD.

*** #### Reassembly

1. Align the indents in the lid with the tabs on the frontplate. 2. Install the lid with a straight, downward motion, making sure the tabs stay aligned.

3. Align the backplate with the rear i/o. 4. The silver EMI tabs may block some of the ports. 5. Use a flathead screwdriver to push the tabs above the ports. 6. Reinstall all the Phillips screws and the process is complete.

*** ### VESA Mounting

1. Unpack the VESA mounting plate and remove the bubble wrap. 2. Be sure not to throw away the screw bag inside.

3. You should have everything pictured here.

4. Use the smaller of the included screws to attach the mounting plate to the bottom of your system. 5. 4 screw holes should line up. Location will vary depending on model.

6. Locate the VESA screw holes on the back of your monitor or mounting arm.

7. Install the 4 bolts hand tight. 8. Hang the system on the back of the display by lining up the bolts with the holes. 9. Push the bolt head through the center of the + cutouts and slide the system down to lock in place.

Locate the PWR\_BAT1\_SIO\_AT1 jumper on the motherboard 2. Add a jumper to short the pins together 3. This will enable the system to automatically power on when power is applied to the board

**BIOS Autopower** 1. Press DELETE as the system is powering on to enter the BIOS menu 2. Navigate to the Chipset page 3. Set "Restore on AC/Power Loss" to "Power On" 4. This will enable the system to automatically power on when power is applied to the board

### Clear CMOS Disconnect the system from all wire connections (power, ethernet, video, etc), then:

1. Locate the clear CMOS jumper 2. Move the jumper over by 1 pin 3. Wait 30 seconds 4. Restore the jumper to its original position 5.
