The computer motherboard can be turned on without a battery. However, because there is no set setting information and system date and time, it will ask you to set up or press a function key similar to F2 to use the default settings, and set Once it is done, it cannot be saved. It will be repeated next time the computer is turned on, but it will not affect the startup and use of the computer.
Nowadays computers do not have floppy drives. Generally, a CD-ROM drive or a hard disk is required to boot the computer when starting the system. There are also some motherboards that will automatically protect themselves due to lack of power supply when there is no power, and may not be able to boot. First of all, I suggest you replace the motherboard battery. Then according to the problem you described, it should be caused by the memory module not making good contact and the motherboard not detecting the memory module. It is recommended to unplug the memory module and wipe the contact points. Extended information The motherboard battery is used to record the time of the computer system, that is, to maintain the accuracy of the system clock. When the power is insufficient, the time will return to the factory date, and to record the hardware information used during startup, that is, to maintain the CMOS BIOS. information. If the motherboard battery is out of power and the computer is not turned on for two days, the system time will not be accurate after starting up and will return to the time when the motherboard was produced. When the battery is insufficient, the system time will slow down. For example, it is January 1, 2013.10 :00, it may be displayed that the displayed time is 9:00 on January 1, 2013, which is easy to identify.

Extended information
The motherboard battery is used to record the time of the computer system, that is, to maintain the accuracy of the system clock. When the battery is insufficient, the time will return to the factory date, and it will also record the startup time The hardware information to be used is the BIOS information that maintains CMOS.
If the motherboard battery is out of power and the computer is not turned on for two days, the system time will not be accurate after turning on the computer, and will return to the time when the motherboard was produced. If the battery is insufficient, the system time will slow down. For example, it is 2013 now. At 10:00 on January 1, 2013, it may be displayed that the displayed time is 9:00 on January 1, 2013, which is easy to identify.
The main purpose of the motherboard battery is to provide a steady supply of power to the BIOS. If the motherboard battery is powered off, the data saved in the computer BIOS will be restored to the initial settings, factory settings and factory time.
All the data in our computer will be cleared and restored to the system and state of the computer just after we bought it.
If we have changed the settings in the BIOS, we will not be able to enter the computer system and desktop when we turn on the computer. We must press f1 every time to enter the system. Expanded information: If the motherboard battery is out of power and the computer is not turned on for two days, the system time will not be accurate after turning on the computer. It will return to the time when the motherboard was produced. If the battery is insufficient, the system time will slow down. For example, it is January 2013. At 10:00 on the 1st, it may be displayed that the displayed time is 9:00 on January 1, 2013, which is easy to identify. 1. As soon as the computer is turned on, the computer prompts, CMOS ERROR PRESS F1 TO LOAD DEFAUL (similar to this in English, prompting you CMOS error, allowing you to restore default values).
2. After the first recovery, when you enter the system, it prompts you that the time is wrong. Please change the time.
3. Cut off the power, unplug the power cord from the back of the chassis, and wait a few seconds. Plug it in again.
4. When turning on the computer, the first step appears again.
5. After entering the system, the system time is wrong.
Then gently open the case, and then lay the case sideways so that it is easy to observe. Find a round battery with a diameter of about 1.5-2.0CM. Then press the clip on the battery slot and the battery will pop out. , then press down the new battery and make sure it is installed firmly. At this point, the motherboard battery has been replaced. Now gently install the chassis.
This statement is incorrect.
There is a button battery on the motherboard, which is used to remember some settings. If this battery is dead, the computer will not remember some settings, such as date and time, etc. But it won't shut down. If the motherboard is not used for a long time, the battery may run out of power. You can buy the same battery and replace it after the host is powered off. If the motherboard cannot be turned on after being unused for a long time, you can check to see if some diodes on the motherboard have exploded: usually they are flat, if they are bulging, they should be broken. Then the motherboard will not work properly. If it's worth repairing, find someone to repair it. The parts themselves are not expensive, but handwork may be more expensive. If the motherboard is too old, it's not worth repairing.A dead computer battery will not affect the startup of the computer, but will affect the computer time. That is to say, after adjusting the time, shut down and then restart, the time will return to the previous time, the bios information will return to the original state, and the startup sequence will change. Booting the floppy drive
The motherboard battery is out of power, and the following faults may occur.
1. Every time the computer is turned on, the computer time is restored to the factory-set time. Even after resetting, restarting the computer will still restore it to the initial time.
2. The computer Bios settings cannot be saved. If you restart the computer, the previously set BIOS items will be invalid and will be restored to the original settings.
3. The computer cannot start up normally, and the monitor has a black screen, etc.
It is necessary to replace the battery with a new one so that the computer can display and work normally.
