BIOS: frequently asked questions

Here are answers to some common questions about basic input/output
system (BIOS).

What is BIOS?
BIOS is a program built into personal computers that starts the
operating system when you turn on your computer. It is also referred to
as system firmware. BIOS is part of your computer's hardware and is
separate from Windows.

Do I need to do anything with BIOS?
No, BIOS doesn't need to be managed and you don't need to change any
settings. Advanced users might choose to change certain settings, such
as the order the computer searches devices when starting.

What kind of BIOS does my computer have?
You can view general information about your computer's BIOS in System
Information.

Click to open System Information.

Click System Summary in the left pane, and then look under BIOS
Version/Date in the right pane to view the BIOS manufacturer, version
number, and the date the BIOS was released. For specific information
about the BIOS used by your computer, check the information that came
with your computer or go to the computer manufacturer's website.

How do CMOS and ACPI relate to BIOS?
Complementary metal oxide semiconductor (CMOS) refers to a chip inside
your computer that saves your BIOS settings. As a result, the terms CMOS
and BIOS are sometimes used interchangeably. For more information, see
What is CMOS?

Advanced Configuration and Power Interface (ACPI) is an industry
standard that defines power management features and other configuration
information for computers. Some previous versions of BIOS don't support
ACPI, and so the computer might not successfully enter advanced power
modes such as sleep or hibernate. For more information, check the
information that came with your computer or go to the computer
manufacturer's website.

How do I access my computer's BIOS?
Procedures vary depending on the BIOS manufacturer. Usually, you must
press a key (such as F2, F12, Delete, or Esc) or a key combination
immediately after you turn on your computer before Windows starts. For
more information, check the information that came with your computer or
go to the computer manufacturer's website.

How do I update BIOS?
Procedures vary depending on the BIOS manufacturer. If you think you
need to update your BIOS, check the information that came with your
computer or go to the computer manufacturer's website.

Warning
Be careful when changing BIOS settings. The BIOS interface is designed
for advanced users, and it's possible to change a setting that could
prevent your computer from starting correctly.

Updating BIOS should only be done if necessary (to solve a compatibility
problem, for example). It can be a complicated process, and if an error
occurs, your computer could be rendered inoperable. Be sure to follow
the manufacturer's instructions exactly.

When it rains it pours. The Toshiba LP W-7 64 went dark. It was fine, was
shut off and when I hit the On button a few days later, just a black screen
with a blinking " - " in the upper left-hand corner. Tapping the F8 is
supposed to bring up Safe Mode (as per Google) but instead up came a screen
to do a memory scan. After it finished I tried again and it came up with 6
tabs of technical info that's alien to me. None of the tabs were for Safe
Mode. I had no way to know what to do on any of the screens. Anyone know how
to get Safe Mode to come up on a Toshiba W-7?

Where do I go from here? The LP actually gets little use and is like new. I
hate to recycle it.

I noticed a few days before that the battery wasn't charging. Since it was
almost always used plugged in, it didn't matter.
