Lost power when updating bios accounting consolidating financial statements
I have old Asus Notebook that I have not used for 1 year and more (but my dad & brother sometimes used it).
The notebok battery has already broken so I detach it from the notebook.
In some cases this can help enable the CMOS battery to retain its settings for longer.
If this doesn't resolve your issue replace your CMOS battery.
All this time, there is no problem of BIOS date/time resetting itself until recently.
A computer's Basic Input-Output System (BIOS) is embedded software on a motherboard.
When you turn on your computer, the BIOS activates the hardware and enables the interaction of the operating system and the hardware and hardware.
If your computer was manufactured before 1995, we recommended that you contact the manufacturer to determine if the motherboard's BIOS is Y2K compatible.Because the bios battery is used to retain the settings of the Date and time RTC Real Time Clock. that is why the battery is there to keep the time and date right. Isn't it cmos battery alone is enough to save the date/time setting? I bought the notebook at 2005, so it's been about 7 years. It has a Negative spring plate at the bottom and two positive folds at the top that make contact with the battery... I only detach the notebook battery, so that means I only use power adapter to start the notebook. Duh, I tried to diassemble the notebook, but it's hard. Bought new battery but CMOS still resets the date etc. So i bent them slightly untill i could test the signal on the back of the and - pins on the motherboard... I also remember that I had set a password for the BIOS but now it's gone, all settings seems back to default. But interesting thing that I found if I restart or turn-off-then-turn-on the notebook without unplugging the power adapter, the BIOS date/time are not reset to default.
Because the bios battery is used to retain the settings of the Date and time RTC Real Time Clock. that is why the battery is there to keep the time and date right. Unplug the main power without a Cmos battery = Bios restet every time. Just be careful not to break them when you bend them..are fragile.Because the flash of the OC BIOS settings isn't working, I've tried manually changing everything again manually and it does work..until the next time I unplug the whole machine or turn the power supply off.
