Lesson 3 Chapter 3 - Managing and Maintaining Laptops Flashcards
What are some maintenance duties a tech would have to do for laptops? (3)
- Power Management
- Keep it clean
- Avoiding excess heat
What are some maintenance duties a tech would do for laptops the same as desktop PCs? (4)
- Keep OS up-to-date
- Keep device drivers updated (use stable recent drivers)
- Keep an eye on storage device health with tools
- Delete unwanted files
What are 3 types of laptop batteries used over the years? Which one is in use today?
- Nickel-Cadmium (Ni-Cd)
- Nickel-Metal Hydride (Ni-MH)
- Lithium-Ion (Li-Ion)
Why are Li-Ion batteries more in use today?
Li-Ion batteries have a higher energy density per weight and are less affected by external factors
What should a tech do if they’re trying to replace a laptop battery? (2)
- Check to see if it’s easily removable with a tab/notch
- Consult manual on how to remove it to save time
What are 5 important tips when working with batteries?
Storage, Draining, Charge, Handling, Green
- Keep it in a cool place (no freezers)
- Don’t completely discharge the battery (have limited charge cycles) unless battery calibration
- Keep the battery charged to at least 70-80%
- Don’t touch ruptured or broken batteries, dangerous chemicals are toxic and flammable
- Always recycle old batteries
What is power management?
Components
Power management is turning off unnecessary components to conserve battery power
What 3 parts of a computer work together to reduce battery drain?
- Hardware
- BIOS/UEFI
- OS
What are the 6 PC power states?
S0 = on
S1-S4
S5= off
What happens when a computer goes to Sleep/Suspend? What number is this power state?
Sleep/Suspend (S3) = the components are turned off except for the memory
What happens when a computer goes into Hibernate? What number is this power state?
Hibernate (S4) = Hibernate saves the system state by copying data and applications from RAM into non-volatile memory and powers the computer down. When starting back up, it takes longer but loads data and applications back into RAM
How do you get to the power management settings?
Control Panel > Hardware and Sound > Power Options
What are the 3 power plans?
- Balanced
- High Performance
- Power Saver
In terms of power management, what is Standby?
Standby is when the display turns off but the computer is still “awake”
What is standby called in Windows 8 and Windows 10? Can you directly trigger it?
Windows 8 = Connected Standby
Windows 10 = Modern Standby
What does turning on USB Selective Suspend allow you to do?
USB Selective Suspend allows you to turn off a specific USB device when not in use to avoid turning off the entire USB hub
How do you get to the USB Selective Suspend option?
Control Panel > Hardware and Sound > Power Options > Change Plan Settings > Change Advanced Power Settings > USB Settings
What are 3 specific power management options on the 1102 exam you should know?
- Standby
- USB Selective Suspend
- Fast Startup
What is Fast Startup?
Fast startup doesn’t shut down the computer fully (keeps some Windows core files loaded) so that the computer can start up faster
What are 2 problems that having Fast Startup can cause?
- Can cause Wake-On LAN to not work properly
- If you need to do a full system restart to fix an issue, you won’t be able to with Fast Startup
What are 2 ways around Fast Startup?
- Shutdown like normal, hold down the power button for 10 seconds to forcefully shut down the computer all the way
- Disable Fast Startup in the Power Options in Control Panel (Choose what the power button does)
What’s a mode that’s a fast way to disable power-sucking components on laptops?
Airplane Mode
What are 2 ways to enable/disable airplane mode? Which method has priority over the other, recognition-wise?
- Hardware switch/button or keyboard combo
- Disable in Windows (Network settings)
Hardware switch/button will have priority even if it’s disabled in Windows
What are 4 additional ways to reduce battery usage and save power?
switches, modes, keyboards, display
- Turn off Wi-Fi antenna/Bluetooth with switch or keyboard combos
- Airplane Mode
- Turn off backlight keyboards
- Reduce the brightness of the display
What are 2 things you should NOT use when cleaning a laptop?
NO:
glass cleaner
water
Oh no! You spilled water on your keyboard! What should you immediately do?
How can you speed up the process?
Turn off the laptop immediately, wait for it to dry
Can also take out the keyboard (refer to manual) and use a hairdryer to speed up the process
What are 7 ways to control excessive heat on a laptop?
power, air, keyboard, fan, utility, disassemble
- Use power management even when plugged into AC outlet (esp in warm room)
- Keep air space between bottom and surface it’s on (hard, flat surface)
- Don’t use keyboard protector for a long time
- If the fan is running fast, change what’s causing heat retention
- Make sure fan didn’t fail if it’s quiet
- Check BIOS/UEFI utility to see if there’s a setting for cooling mode (cool, quiet, high performance)
- Disassemble laptop, blow dirt, debris and hair built up inside
What are 3 tips to properly store a laptop?
protect, battery
- Use a case
- Take out the battery to protect from battery leakage
- Charge the battery to 70-80% periodically to prevent full discharge
NA has what number of volt power outlets, and what power (volts) is found in most of the world’s outlets?
NA ~115V outlets
World ~230V outlets
Many laptops have auto-switching power supplies, what is this? What do these types of laptops need?
travel
Auto-switching power supplies detect the amount of incoming voltage and adjust accordingly
they just need a simple plug converter
What are fixed-input power supplies?
Fixed-input power supplies are only able to accept a certain voltage from an outlet (115V or 230V)
What are two electricity-converting devices a fixed-input power supply might need?
dance
Step Up Transformer
Step Down Transformer
What are 2 security measures?
- Cable lock
- Tracking software with GPS capabilities
