+
+
+
+3. Make sure the tab on the top of the slot is open (pulled away from the slot), then insert the new RAM (or re-seat the existing RAM) into the slot.
+ - Insert the bottom edge first, then push the top edge in until its latch clicks closed, followed by pushing the bottom edge until it clicks into the stationary bottom of the slot.
+ - The RAM stick will only fit in one direction. The larger group of pins goes on the top.
+ - Use the following guide for placement of the RAM sticks:
+ ! [RAM slot order](./img/ram-order.avif)
+4. Replace the left side panel.
+
+## Replacing the GPU:
+
+Thelio Mira AI ships with up to two dedicated GPUs installed in the PCIe 5.0 slots. The top PCIe 5.0 slot supports GPUs up to four slots tall; the bottom PCIe 5.0 slot supports GPUs up to two slots tall.
+
+**Tools required:** Cross-head (Phillips) screwdriver
+**Time estimate:** 15 minutes
+**Difficulty:** Medium ●
+
+### Steps to replace the GPU:
+
+1. Follow the steps above to [remove the left side panel](#removing-the-side-panels) and [remove the front glass](#removing-the-front-glass).
+2. Remove the four screws (two in the front, and two in the back) holding the GPU brace into the chassis.
+
+
+
+3. If necessary, loosen the screws holding the GPU finger(s) in place above and below the GPU(s), then slide the finger(s) away from the GPU(s).
+ - This step is necessary with large GPUs that require the GPU brace to be mounted near the edge of the chassis.
+
+
+
+4. Slide the GPU brace out of the chassis.
+ - Start by pivoting the top edge out of the chassis, then slide the bottom edge inward and upward until it can be removed from the chassis.
+ - Due to manufacturing tolerances, the GPU brace may require significant force to install and remove. Ensure the brace is not forcefully pressing against the GPU or any other non-chassis components when handling the brace.
+5. Unplug any power cables connected to the GPU.
+
+
+
+6. Partially loosen the two back screws holding the PCIe bracket in place, and slide it into the rightmost position.
+
+
+
+7. While holding the GPU, push back the latch on the motherboard (accessible from above the GPU) to free the PCIe connection, then pull the card out of the slot.
+ - The top slot's latch, located at the far end of the motherboard, rotates upward; the other latches rotate away from the slots.
+
+
+
+8. Insert the new GPU (or re-seat the existing GPU) into the appropriate PCIe slot.
+9. Close the back PCIe bracket.
+10. Connect the GPU power cable.
+11. If necessary, adjust the position of the GPU brace fingers.
+ - To adjust the horizontal position of the brace fingers, use the screws at the top and bottom of the brace column (highlighted red below).
+ 
+ - To adjust the height of the GPU brace fingers, partially loosen each finger's singular screw (highlighted cyan above), slide the finger to the appropriate height, and re-tighten the screw.
+ - For large GPUs, it may be necessary to loosen the finger screws before reinstalling the GPU brace into the chassis, then position the fingers and tighen their screws after installing the GPU brace.
+ - To move a GPU finger between the top and bottom half of the GPU brace, the GPU finger screw can be completely removed.
+12. Reinstall the GPU brace, front glass, and left side panel.
+
+## Replacing the M.2 drives:
+
+Thelio Mira AI R6-N4 has three M.2 storage slots. All four slots are M-key and size 2280.
+
+- Slots 1 and 2 support PCIe NVMe Generation 5.
+- Slot 3 supports PCIe NVMe Generation 4.
+ - When Slot 3 is in use, the bottom PCIe slot (labeled `PCIEX16(G4)`) is disabled.
+ - Slot 3 is not used in any factory configurations, but is available for aftermarket upgrades.
+
+**Tools required:** Cross-head (Phillips) screwdriver
+**Time estimate:** 30 minutes
+**Difficulty:** Medium ●
+
+### Steps to replace the M.2 drive:
+
+1. Follow the steps above to [remove the left side panel](#removing-the-side-panels).
+ - Slot 1 can be accessed without removing any other components.
+ - Depending on the size and number of the GPU(s), accessing Slot 2 and/or Slot 3 may also require removing the [front glass](#removing-the-front-glass) followed by the [GPU brace and GPU(s)](#replacing-the-gpu).
+2. For slots 1 and 2, remove the M.2 heatsink for the slot(s) you wish to access by pushing the rectangular latch away from the slot.
+
+
+
+3. To remove a drive from a slot, push the corresponding grey lever outwards to release it, then pull it out of the slot.
+
+
+
+4. To insert a drive into a slot, insert the connector, then secure the opposite side by pushing the opposite side onto the grey lever until it clicks into place.
+ - If you're using Slot 3 for the first time, it may be necessary to rotate the grey latch into the correct orientation first.
+5. Reinstall the M.2 heatsink(s).
+ - By default, the thicker heatsink is installed over Slot 1, while the thinner heatsink (with four dots on the front) is installed over Slot 2.
+ - If you're using Slot 1 or Slot 2 for the first time, peel the blue protective plastic off of the corresponding thermal tape behind the slot and on the heatsink.
+
+
+
+6. Reinstall the GPU, GPU brace, front glass, and left side panel as applicable.
+
+## Clearing the CMOS:
+
+UEFI settings and the computer's hardware clock are stored on the CMOS. By using a jumper on the motherboard, the CMOS can be cleared (to reset these settings) without removing the CMOS battery.
+
+**Tools required:** Cross-head (Phillips) screwdriver
+**Time estimate:** 15 minutes
+**Difficulty:** Medium ●
+
+### Steps to clear the CMOS:
+
+1. After ensuring the system is unplugged from power, follow the steps above to [remove the left side panel](#removing-the-side-panels).
+2. Use a metal object to bridge the gap between the two pins on the `CLRTC` jumper (located below the bottom PCIe slot) for 10 seconds.
+
+
+
+3. Remove any metal objects touching the `CLRTC` jumper, reinstall the left side panel, and plug the computer back into power.
+ - To re-enter UEFI settings following a CMOS reset, hold the `Delete` key on the keyboard during boot.
