Teardown and Upgrade Process:

1. Prepare Your Laptop:
   • Ensure the laptop is turned off.
   • Disconnect all power sources and peripherals.
2. Remove the Back Cover:
   • Use a Phillips screwdriver to remove all screws from the back cover.
   • Gently pry off the back cover using a plastic prying tool.
3. Battery Replacement:
   • Locate the battery and disconnect it by sliding the connector down towards you.
   • Remove the battery and replace it with a new one. The model number for this battery is typically ‘MXV9B’ or ‘CN-05V2M’.
4. M.2 Drive Upgrade:
   • Identify the M.2 drive and remove it by unscrewing and sliding it out.
   • To upgrade, insert a new M.2 drive (e.g., 512 GB or 1 TB) and secure it with screws.
5. RAM Upgrade:
   • Locate the RAM slots next to the CPU fan.
   • To upgrade, insert additional DDR4 RAM into the available slot, ensuring it clicks into place.
6. Additional Components:
   • The motherboard hosts essential components, including the CPU fan, heatsink, and I/O board.
   • The heatsink can be removed for cleaning or applying new thermal paste.
7. Reassembling the Laptop:
   • Once all upgrades are complete, carefully reassemble the laptop by reattaching the back cover and securing it with screws.

Tips and Recommendations:

• Handling Components: Be gentle when handling internal components, especially when disconnecting and reconnecting cables.
• Thermal Management: If your laptop overheats, consider cleaning the fan and applying new thermal paste to the CPU and GPU.
