That said, laptop components and designs have become better Medium r Practice standardized. Using components sourced from the laptop Low vendor is still recommended, but basic upgrade options, such as v Assessments system memory and fixed disks, have become much simpler. Continue  g Flashcards Some FRUs can be accessed easily by removing a screw plate on the back cover (underside) of the laptop. This method generally Category j Game Center provides access to the fixed disk, optical drive, memory Topic 8C: Install and Configure modules, and possibly adapter card slots for components such Laptop Hardware " Resources as Wi-Fi cards and cellular radios. Upgrading RAM Modules Laptop DDRx SDRAM is packaged in small outline DIMMs (SODIMMs). As with DIMMs, a given SODIMM slot will only accept a specific type of DDR. For example, you cannot install a DDR4 SODIMM in a DDR3 slot. The slots are keyed to prevent incompatible modules from being installed. Two SODIMM RAM modules. The modules stack one over the other. When the side catches are released, the modules pop up at an angle for easy removal. (Image courtesy of CompTIA.) A SODIMM slot pops-up at a 45º angle to allow the chips to be inserted or removed. Sometimes one of the memory slots is  easily accessible via a panel, but another requires more extensive disassembly of the chassis to access. *    There are a couple of other laptop memory u Learning Plan module form factors, including Mini-DIMM and Micro-DIMM. These are smaller than SODIMM C Strengths & Weaknesses and are used on some ultraportable models. Always check the vendor documentation before k Lessons obtaining parts for upgrade or replacement. X PBQs Upgrading Adapter Cards Depending on the design, adapters for modems, wireless cards, , Labs and SSD storage cards may be accessible and replaceable via screw-down panels. Note that there are several adapter formats, r Practice notably Mini PCIe, mSATA, and M.2, none of which are compatible with one another. v Assessments You can obtain mini PCIe or M.2 adapters for laptops that will g Flashcards provide some combination of Wi-Fi, Bluetooth, and/or cellular j Game Center data connectivity. Remember that when upgrading this type of adapter, you need to re-connect the antenna wires used by the " Resources old adapter or install a new antenna kit. The antenna wires are usually routed around the screen in the laptop's lid. The antenna connections can be fiddly to connect and are quite delicate, so take care. Wi-Fi adapter installed as a mini PCIe card. Note the antenna wire connections. (Image courtesy of CompTIA.) If installing an adapter with GSM or LTE cellular functionality, remember to insert the SIM card as well.  Report Content Errors
