QUESTIONS AND ANSWERS SURE A+
✔✔"Bootable device not found" means... - ✔✔If the PC fails to boot from the fixed disk,
it is either faulty or there is file corruption.
✔✔Read/write failure— such as "Cannot read from the source disk" (SSD) - ✔✔On an
SSD, the cause will be one or more bad blocks
✔✔Read/write failure— such as "Cannot read from the source disk" (HDD) - ✔✔HDD,
This is typically caused by bad sectors . A sector can be damaged through power failure
or a mechanical fault.
✔✔Blue screen of death (BSOD) - ✔✔A failing fixed disk and file corruption may cause
a particularly severe read/write failure, resulting in a system stop error (a crash screen).
✔✔There are two main scenarios for RAID failure: - ✔✔1.) failure of a device within the
array
2.) failure of the whole array or volume.
✔✔This RAID configuration has no redundancy, speed is more important that reliability.
- ✔✔RAID 0
, ✔✔Correcting overheating issues... - ✔✔Ensure that the CPU fan is working.
Make sure the heat sink is properly fitted.
Always use blanking plates to cover up holes in the back or front of the PC.
✔✔...is a part of the chipset that keeps track of the calendar date and time. Its a coin
cell lithium battery. - ✔✔Real time clock (RTC) battery (CMOS)
✔✔How to fix "dim image" - ✔✔Use the OSD (on-screen display) to check the
brightness and contrast controls to make sure they are not turned all the way down.
✔✔How to fix "fuzzy image" - ✔✔Output resolution does not match the display device's
native resolution, the image will appear fuzzy. Use the OS to change the output
resolution or update the driver.
✔✔How to fix "flashing screen" - ✔✔Check the video cable and connectors. A flickering
or flashing image could also be caused by the display's backlight or circuitry starting to
fail.
✔✔Dead Pixels - ✔✔Defects in a flat-panel monitor may cause individual pixels to be
"stuck" or "dead." Fixed pixels can also sometimes be reactivated by gently pressing or
tapping the affected area of the screen with a stylus or pencil eraser.
✔✔Burn-In - ✔✔a ghost image is "burned" permanently onto the display. use
screensaver
✔✔How to fix "Incorrect color display" - ✔✔Color calibration (or workflow) refers to a
process of adjusting screen and scanner settings so that color input and output are
balanced.
✔✔Printer Wi-Fi connectivity can be established in two different ways: -
✔✔Infrastructure mode and WiFi Direct
✔✔Printer Property Traits: - ✔✔updating the driver, printing to a different port, sharing
and permissions, setting basic device options (such as whether a duplex unit or finisher
unit is installed), and configuring default paper types for different feed trays
✔✔Printer Preference Traits: - ✔✔orientation of paper or whether to print in color or
black and white, Paper/Quality tab and Finishing tab, printing on both sides etc.
✔✔Types of Network scan services: - ✔✔Scan to email
Scan to folder or SMB
Scan to cloud
