Aloha, replaced cmos battery (assumed dead) because emachine hangs on E logo screen and neither option to press F2 (bios settings) or F10 (boot menu) do anything. Tried putting in Recovery media back up disc but also nothing, tried putting in windows xp disc and nothing....ideas?

Step 1:
All computer systems go through a set of instructions called the Basic Input/Output System (BIOS) when they are turned on. The BIOS checks all of the hardware and software installed on the computer to make sure they are working properly before loading the operating system. You may need to access the BIOS menu periodically to find out the current version of the BIOS you have if there are upgrades available. The command you use to access the BIOS settings on an Emachines computer will vary depending on the specific model you have.

Access the Start menu and click "Shut Down." Select the "Restart" option. Wait for the Emachines logo to appear on the screen as the computer begins booting up again. Press the "Tab" key when the logo appears and see if the computer switches to the BIOS menu. Press the "Escape," "Delete," or "F2" keys if the "Tab" key doesn't take you to the BIOS menu screen. Use the right arrow key to highlight the "Main" entry and press Enter. Scroll down to the heading labeled "BIOS version." Check the long string of numbers and letters under the "BIOS version" heading to locate the current BIOS version your Emachines is using. Press the "F10" key to exit the BIOS menu screen and finish booting up the computer's operating system.

Your cmos battery is dead and needs to be replaced.

Restart your computer
during the boot process you will see on the screen to press a certain key usually Delete or F2 to enter setup
this will differ depending on which bios you have

Press and hold that key during the boot up process to enter BIOS
if you have changed any of the BIOS settings by mistake

you can load failsafe or optimised defaults using the arrow keys you can after you make any changes in BIOS press Esc then press the F10 button save to cmos to restart

CMOS is an on-board semiconductor chip powered by a CMOS battery inside computers that stores information such as the system time and date and the system hardware settings for your computer..


removing the cmos battery for 15 to 30 mins should reset your cmos
some motherboard cmos batteries are soldered in

failsafe or optimized defaults should do the job

hope this helps

There are 2 things you could do. 1) you can change the boot settings in the bios or 2) you can choose the the boot device on the logo screen or bios screen on startup. to do #1 you need to press either DEL or F2 on the logo/bios screen. inside you can change the boot priority. for #2 once you see the logo/bios screen you can either press F10, F11 or F2 to go to the boot device selection. To know which buttons to press for these once you are on the bios screen the right button will be flashed.

Try booting from a Flash

Hi Krishna. Could be that the processor's cooling fan is no longer functioning and then the processor instantly overheats and everything STOPS !!! Could be the RAM memory chips not in good state anymore .....Could be that (while it tries to determine what hard drive is in there) the hard drive is BAD and cannot be identified... that would also just STOP everything. It really is quite a few things that could cause that

when upower up press
"del"
F2
F8
F12
F10
try above
then u can able to enter in bios

THE CMOS BATTERY HAS FAILED AND A NEW ONE HAS TO BE INSTALLED

PUSH THE F10
SO YOU CAN GO INTO THE BIOS
SET THE TIME, DATE, KB, HD, CDROM,DVD,FLOOPYS, ANOTHER DEVICES YOU MAY HAVE
F10 SAVE
YES
REBOOT
EVERYTHING SHOULD BE OKAY

reinstall the os

This machine is one of the first "legacy free" models which means there are no BIOS options to change. All settings and resources must be assigned by the OS.
For details, please check the "legacy free" FAQ on MS Knowledge base.
If you are trying to access the BIOS to change boot order so that you can boot from a CD, hold down the 'c' key during POST/boot. This will case your laptop to boot from CD-ROM.
