Laptop hardware Flashcards
What are the common battery technologies used in laptops?
Lithium-Ion (Li-ion) and Lithium-Ion polymer (LiPo)
Describe Li-ion and LiPo batteries.
Do they last long? Whats the memory effect?
-no “memory effect” meaning you can use some charge and charge it up again without limiting the amount of capacity the battery has.
-however, each time you charge the battery it diminishes the capacity just a bit so over a time you might realize that the charge doesnt last as long
-basically these batteries need to be replaced down the road because the full charge doesnt last as long
Most-used component of a laptop?
Keyboard
Describe construction of a keyboard.
Few screws and a single ribbon cable, usually. Cable is used to connect/disconnect from laptop motherboard.
What is a general use of the function key? (fn)
To access the secondary functions usually located at the top of a laptop keyboard.
What is a common laptop keyboard repair?
How should you go about working with the mentioned repair?
Removing/replacing keycaps because something fell under keys or keycap is broken.
Check with manufacturer’s instructions for recommendations on what to do when repairing the laptop keyboard. Keycaps an components under keycaps are easy to break.
What form factor would be used to increase your laptop’s memory?
Can all laptops have its memory increased? Why
?
Adding a Small Outline Dual In-line Memory Module (SO-DIMM).
No. Those laptops have their memory module soldered to the motherboard so changes cannot be made unless the entire motherboard is replaced.
In a repair, how can you go about increasing your laptop’s memory?
Add a SO-DIMM card. Usually theres an opening at the bottom of the laptop to easily add and remove memory modules.
Some laptops do not have a SO-DIMM card but instead have their memory module soldered to the motherboard, thus not allowing you to increase the memory without changing the entire motherboard.
What is a form factor?
The size, configuration, or physical arrangement of a computing device. Term used to describe internal components such as a motherboard.
What is a magnetic disk?
Usually found in older laptops as a form storage.
This is the hard drive that we traditionally think about.
Looks like a large, silver spinning disk about 2.5 inches in laptops (~3.5 inches in desktops).
What form of storage do newer laptops usually have?
Solid-state drives (SSD).
What is a SSD? Describe and give size. Give one advantage.
Solid-state drive.
no moving parts inside thus silent, fast access time, less latency.
2.5 in form factors
advantage is greatly increased speed for reading and writing data to the device
What happens when you upgrade from a hard drive to an SSD?
You can greatly improve performance of almost any device.
What is a M.2 Interface? Size and benefits?
Smaller form factor of an SSD
smaller than SATA connected SSD; size of a stick of chewing gum
smaller size allows for more storage in smaller space; no cables like how you’d find on a SATA connected SSD; modular so you can easily screw in more for additional storage
Where would you find a laptop’s storage?
On the back usually under the entire cover or seperate in a small window that gives access to the storage area.
