Mush Read For CompTIA A+ Module / Objective 1.1 Laptop Hardware:
This portion of this video is significant in considering whether your Module / Objective 1.1 is complete.
Hard Drive Storage:
Most laptop computers use one 2.5-inch storage drive that comes in one of three common choices: HDD, SSD, or SSHD. Each has strengths and weaknesses, and each could be the right choice, depending on the scenario presented:
- Hard disk drive (HDD): These magnetic disks have been a standard option for years and combine low cost with large capacity. However, they are slower than the other options. Because they use magnetic disks and moving parts that can wear down, they are the least reliable of the three options.
- Solid-state drive (SSD): SSD is a flash memory drive with no moving parts. It is much faster than an HDD when booting and storing or retrieving data. Although SSDs currently cost more than HDDs, their prices are dropping and their capacity is improving. Many newer laptops have M.2 expansion ports and can support an M.2 SSD card that is directly mounted to the circuit board for even faster reading.
- Solid-state hybrid drive (SSHD): An SSHD combines a solid-state cache with magnetic capacity. It uses a memory manager to choose the most common files for the fast cache.
| Type of Storage Drive | Cost | Capacity | Speed | Reliability |
|---|---|---|---|---|
| HDD | Least expensive and readily available | Highest capacity | Slowest because of moving partsvand magneticvdisks | Has movingvparts that canvwear over time |
| SSD | Most expensive, but price is dropping | Lowest capacity, but improving | Fastest | Has no moving parts |
| SSHD | Midrange cost | Blends high HDD capacity with fast solid-state cache for most-used files | Blends fast solid-state cache with slower magnetic storage | Has moving parts that can wear out, but spins less than HDD |
Random Access Memory (RAM):
Random access memory (RAM) is the workspace where data is loaded while being processed by the CPU. Laptop computers use various types of double data rate (DDR) synchronous dynamic RAM (SDRAM) dual-inline memory modules (DIMMs) with speeds and capacities similar to the RAM used in desktop computers. However, laptop computers use a smaller RAM module form factor known as small outline DIMM (SODIMM or SO-DIMM). Current laptop models use DDR5 or DDR4 SO-DIMM, but you might encounter laptops that use older DDR3 SO-DIMM modules.
| Type of RAM. | Descriptio. |
|---|---|
| RAM (random access memory). | Volatile memory that is not used for storage. |
| SDRAM (synchronous dynamic RAM) | Combination of static RAM and dynamic RAM. |
| SDR SDRAM (single data rate SDRAM) | Single data rate means that the internal clock rate and input/output are the same. |
| DDR SDRAM (double data rate SDRAM), DDR3, DDR4, DDR5 | Double data rate allows for nearly twice the bandwidth by supporting data transfers on the rising and falling edges of the clock cycle. DDR5 is the latest generation. |
| DIMM (dual inline memory module) | Form factor used in desktops. |
| SODIMM (small outline DIMM) | Form factor used in laptops. |
In the table, given below, you can see the main differences between all the generations of Double-Data-Rate (DDR) RAMs. In the table all the things are discussed assuming a single RAM stick if you increase your RAM stick count then it'll be the multiple of your count.
In this table, you can find the Name, Generation, Speed in (MHz), Voltage (power a RAM stick uses), Capacity (how many GBs a single stick has), Pin Count (the connectors where the RAM stick connects to Laptops), and at last you can find Used In column (where and when it is common). With the new generations the Speed, Capacity, and Pin Count increase, and Voltage (Power) consumption is reduced.
| Name | Gen | Speed | Voltage | Capacity | Pin Count | Notch Location | Used In |
|---|---|---|---|---|---|---|---|
| DDR1 SODIMM | Gen 1 | 100-200 MHz | 1.5-2.5 V | Up to 1GB | 200 pins | Older laptops, netbooks, and small-factor PCs | |
| DDR2 SODIMM | Gen 2 | 200-400 MHz | 1.8 V | Up to 4GB | 200 pins | Older laptops, notebooks, and small form-factor PCs | |
| DDR3 SODIMM | Gen 3 | 400-800 MHz | 1.5 V | Up to 16GB | 204 pins | After 36 pins | Laptops, notebooks, and small form factor PCs (2010-2015) |
| DDR4 SODIMM | Gen 4 | 800-1600 MHz | 1.5 V | Up to 64GB | 260 pins | After 144 pins | Modern laptops, notebooks, and small form factor PCs (2015-present) |
| DDR5 SODIMM | Gen 5 | 1600-3200 MHz | 1.1 V | Up to 128GB (and beyond) | 262 pins | After 116 pins | Latest laptops, notebooks, and small form factors PCs (2020-present) |
Exam Tip:
When adding RAM to a laptop, be sure to determine the supported type, speeds, and sizes for the particular laptop model. Many memory vendors have online system checkers or databases you can use to find compatible modules for a given system.
Laptop Motherboard Featuring Four RAM Slots:
Almost every laptop motherboard features up to two slots for RAM and soldered memory that can't be upgraded. Typically labeled as A1 and B1 (or sometimes A2 and B2) and allow for installation of up to two RAM sticks (modules). If you want to install RAM in both slots you should install the RAM that has High Speed in the first RAM slot (it will work according to (the clock Speed of) faster RAM).
Note:
The Laptop Repair 101 website (www.laptoprepair101.com) provides
many useful resources, including links to major vendors’ laptop service
manuals, illustrated step-by-step procedures for the removal of many
components, and links to parts sources.
