- do a bios update (or downgrade if needed) to see if it fixes the issue

- but probably the BIOS battery is not keeping the proper voltage anymore, and it automatically resets the BIOS (do the bios setting that u change, remain changed after unpluging/pluging the comp ?!). Try keeping the computer pluged in for a day and see if the battery charged properrly (if the set date remains )... if not ..change the battery.

- as for the self starting, there is a setting in the BIOS, that activates/dissables that ! - see u;re user manual ...

What is BIOS?


The BIOS information is typically found at or near the top of the POST screen for a very short time ALR PC non / PCI = CTRL+ALT+ESC AMD advanced micro devices=BIOS = DEL Award BIOS = DEL Dtk Datatech Enterprises Co. BIOS = ESC Phoenix BIOS = CTRL+ALT+S Phoenix BIOS = CTRL+ALT+INS 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.. this will reset your cmos
Sleep mode is a convenient power-saving feature used on both laptops and desktop computers. This feature powers down hard disks, monitors, wireless devices and any other power-consuming peripherals without turning the unit completely off and necessitating a reboot. Sleep mode can prevent battery drain if using a laptop or mobile device while away from the power supply. This mode is useful when quick access to a computer is needed, but can be irritating if the sleep mode takes a long time to come back from. It is simple to turn sleep mode off, based on the operating system being used.

Go to the "Start" button, then click on "Control Panel." In the control panel screen, click "System and Maintenance," then click on "Power Options." This brings you to the "Select a power plan" page. From the "Select a power plan" page, select the option that says "Change plan settings." This changes the settings on the currently selected plan. Select the "Change advanced power settings" option. Click "Sleep" and then click on "Sleep After" to expand it. If using a laptop or mobile PC, click "On battery" and "Plugged in," then select the "Never" option. This turns off sleep mode for both battery and AC use. If you are using a desktop computer, click "Setting," click the arrow and then click "Never" to turn off sleep mode. Click "OK," then click "Save changes" to save the modification. b> Turning Off Sleep Mode - Mac OS b> Click on the Apple logo at the upper left corner of the screen to open the menu and select the "System Preferences" option. From the "System Preferences" screen, click on "Energy Saver." If you are using a desktop, select "Power Adapter" in the top drop-down menu. In the second drop-down menu, select "Custom." Highlight the "Sleep" tab, then adjust the top slider to the far right, marked "Never." I f you wish the display to stay on, adjust the bottom slider to "Never." Click the red button on the upper left side of the "Energy Saver" screen. If you are using a mobile product or laptop, follow step 2 and select "Battery" from the top drop-down menu. Repeat step 3 to change the settings for battery use. Hope this helps.

incorrect CMOS device not specify

CMOS device(electronics)

A device formed by the combination of a PMOS

(p-type-channel metal oxide semiconductor device) with an NMOS (n-type-channel metal oxide semiconductor device). Derived from complementary metal oxide semiconductor device.

The CMSOS is only a battery to store you're bios/mainboard settings.
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..

The moment that you unplug the power and remove the battery for at least 10seconds, the mainboard will reset it self into the 'default-state'.

This can also be done by selecting 'reset to default settings' in bios screen.

Restart your computer
During the boot process you will see on the screen to press a certain key to enter setup usually the Delete or F2 key
this will vary depending on your computer and operating system

Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart

hope this helps

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!

Computer powers up by its self when first plugged in


Most BIOSes have a setting for what to do after a power failure--stay off, turn on, resume last state. If the user is unplugging the unit before a total legal and proper shutdown, then that might explain why it turns on 'when plugged in'. Disconnecting before completely shut down is detected by the BIOS as a power failure.

Also, killing power to a running system can cause file table corruption, corrupt files, a destroyed operating system, even in rare cases a total loss of everything on the disk.Although, If you mean the computer turns on by its self after it's been turned off (so he unplugs it to keep it from powering on), then it might be "auto awake" settings in the bios, I've seen some bios' have "auto-power on" settings so that signals from network cards or peripherals can power the computer up.

Also It turns out the CMOS battery went out and that probably reset the BIOS so the computer itself was set to turn on by itself when it was plugged in. With a new CMOS battery and a quick setting change the computer is ready to go.

Changed lan settings in post now my bios and xp wont launch


Turn the computer off.
Disconnect the AC power.
Look closely at the motherboard.
Look for 3 pins in a row, with a jumper between 1 & 2.
This is the "BIOS RESET" control.
Move that jumper to connect 2 & 3, for 5 seconds.
to reset the BIOS to its "default" settings.
Move that jumper back to to the 1 & 2 position.
Reconnect the AC power.
Turn the computer on.
Enter BIOS SETUP, to confirm that the "default" settings have been restored.

How to reset bois for a MSI laptop model # ms-no11


1
When you first turn your computer on, you are briefly presented with a BIOS "splash" screen. Somewhere on this screen (just where depends on the manufacturer), are instructions on how to access BIOS settings. Generally, this requires tapping a function key, say F2, while the splash screen is visible. Make note of which key the splash screen says to press to access the BIOS and restart your computer.

2
When the computer boots and the splash screen appears, tap the required function key quickly to enter the BIOS settings screen. You will only have a couple of seconds to hit the right key and if you miss it you'll have to restart the computer and try it again.

3
Once you successfully enter the BIOS settings screen, use the arrow and function keys to navigate the menus. Keep an eye out for an option that says something akin to "reset to factory defaults." If you see this, follow the on-screen instructions to reset the BIOS to the factory settings. Then, confirm your choice and exit the BIOS screen, usually by pressing escape. Congratulations, you are done.

4
If your BIOS does not have an option to return to factory settings, things are more difficult. Because the BIOS is stored in ROM, it must have a constant power supply to store any changes you make to it, otherwise it would reset every time you disconnected your laptop from AC power. Removing power to the BIOS resets it to factory settings and involves disconnecting a small battery attached to the motherboard. On many laptops, the BIOS battery is easily accessible through a door on the bottom of the unit. Unplug the computer, remove the main battery and touch something metal to ground yourself.

5
Remove any screws holding the BIOS battery door in place. Then identify the battery, (it is generally a small lithium "watch" battery), and remove it taking care not to damage any surrounding circuitry. Let the computer rest for a minute or two to discharge any remaining power, and replace the battery.

6
If your laptop does not have an easily accessible door for the BIOS battery, you may have to dive deeper and disassemble the computer to find it. Consult your laptop manufacturer's website for information on replacing or removing the BIOS battery from your model.


Thanks.
Have a great day.
