How to replace the 2.5" HDD ribbon cable? (NUC11PAHi7)?

It sounds like you're dealing with a broken ribbon cable in your Intel NUC 11 (PAHi7), which is a bit tricky, but not impossible to fix. Let’s break it down step by step:

1. Power Off and Disassemble:
   • Make sure the NUC is powered off and unplugged from any power source.
   • Remove the screws that hold the chassis together and carefully open the case.
   • Take note of any other components connected to the motherboard to avoid damage while working.
2. Locate the Damaged Ribbon Cable:
   • The 2.5" HDD ribbon cable typically connects the internal storage (HDD or SSD) to the motherboard.
   • Carefully inspect the ribbon cable to see if it's just dislodged or fully damaged. If it’s just dislodged, you may be able to carefully reattach it. If it’s torn or otherwise broken, a replacement is necessary.
3. Disconnect the Ribbon Cable:
   • Gently disconnect the ribbon cable from both the motherboard and the 2.5" drive port. If there’s a locking mechanism, carefully release it.
   • If you’re not familiar with the connector type, be sure not to force anything — gently wiggle it out if it’s stuck.
4. Find a Replacement Cable:
   • Since the NUC 11 (PAHi7) uses a very specific ribbon cable, you’ll need one that is compatible with the pinout and form factor. The ribbon cable for 2.5" drives typically has a 22-pin or 40-pin connector, depending on the NUC model.
   • The best place to find an exact replacement would be:
     • Intel’s official parts store or Intel’s support page for accessories (though sometimes they don’t list parts separately for NUC models).
     • eBay – Sometimes NUC replacement parts, including ribbon cables, are sold by third-party sellers.
     • Third-party vendors like AliExpress or Amazon may also have compatible cables.
   • Look for part numbers related to the NUC 11 series or, if you have the damaged cable, check the numbers printed on it.
5. Install the New Ribbon Cable:
   • Carefully install the new ribbon cable by connecting it to both the motherboard and the 2.5" drive port.
   • Make sure it’s seated correctly and that the connector’s locking mechanism (if any) is engaged.
6. Reassemble the NUC:
   • After confirming the ribbon cable is correctly installed, reassemble your NUC, making sure all other components are properly connected.
   • Screw the case back together and plug it in to test.

• Ribbon Cable Specifications: Make sure you get the correct length, connector pitch, and pin count for the replacement ribbon. The NUC 11 should have a 2.5" SATA connection, but always verify the specific part number or consult the NUC manual.
• Warranty: Since your NUC is out of warranty and ASUS does not offer repair services for expired warranties, you are on your own for this repair. However, it’s relatively straightforward if you can get the right replacement cable.

If you’re not comfortable performing this repair yourself, consider reaching out to a local repair shop that specializes in computer hardware. They might have the right tools and parts to help you.
