Nothing, the computer will run fine on the default settings usually.
If the CMOS battery dies you lose the settings that are held in the BIOS (Basic Input Output System). These include settings such as date/time, boot order,etc.
Reboot with a good battery and instruct setup to restore the default settings. Setup has to autodetect the hard drive present, and than you will need to set the date.
Data saved in cmos ram cant recovered if ram crashes suddenly but in case bettery or power failler 1) dont eject the ram runddnly wait for halting .2) use alternative system for power .3)detach the ram and place it in another ram reading system and fatch the data.
You will lose all custom settings in the BIOS, and the BIOS will revert to the basic default every time the computer is restarted.
As far as I know, there is really no advanced warning, until the battery starts to fail. For example, on my computer, after using it for several years, the computer started to be unable to maintain the current time. I eventually figured out that this was a result of a weak CMOS battery.
No, you are just changing the patently guidance settings.
The data is CMOS is on a chip called RAM. RAM will lose data when it loses power. A small battery on the motherboard is used to keep continuous power to CMOS when the PC loses power.
If you had installed anything in the PCI-E or any kind of Drive, it will lose all of the hardware configuration to that device. Overall, no performance enhancement will be made. In rare cases, Performance will increase by 1%-3%.
ONLY if your contacts are saved on your SIM card. If they're in the memory - and you re-set your phone to the 'factory settings' - you will lose all personal data including your contacts.
WOOOOOOOOOOOOOOOOOOOHOOOOOOOOOOOOOOOOO.OH YEAH
That's not entirely possible. Large amounts of application data is stored in the Rgistry. You would lose your saved settings for most of your programs.
Yes! Only if you have saved it though!
