I've gotten excellent results using Silicone Rubber... except for the SMell (strong VINEGAR odor!) I'd recommend a Caulk available at your local Home Renovation store.... in the paint department, usually - It has NO ODOR, and easily removed later. Look for a caulk that is mixed with Silicone Rubber.... PAINTABLE CAULK.... hardly any odor, will adhere to plastics, glass, wood.etc... and when your done, or made a mistake, the parts can be separated with mild muscle power! COST: About $4.00 (US), for a 10 Oz Tube. Look for smaller sizes, which are easily kept in your tool box or parts drawers.
This computer uses a Mini PCIe slot card, as you can see in the photo's. You can órder almost any card, from either FENVI brand (Intel) or Artheros (Qualcomm), just make certain you order a card that specifically says it is a HALF HEIGHT Mini PCI-e card. Intel stop producing cards like this after the 7265HMW card but other brands make compatible cards. In the Intel design, any card that ends in 'HMW' is a card that is a mini PCIe card. If you see any other combination of letters then it is not likely to be compatible.
If you have any questions, ask the vendor if the card is compatible with your computer.
