I changed the battery of my computer and I don t recognize the disk? Understand, come in

The motherboard settings of each computer are not very different, you don't say the model of your computer, you don't know how to set up your computer, the main thing is that after you go in, you restore the factory value, load option, click yes after selection, the general computer has two such options,

The question is too simple to answer, except for the one upstairs you, paste it directly.

Available,That is, it has been used.,Including the ones occupied by the set display.,There are also running processes and programs occupied.,It's normal.。 "Generally available", your "general" comes from **. Even if it was originally only occupied, but now it has been added, there is nothing abnormal, and there are too many programs that occupy memory.

It's okay to set up a RAM disk with RAM Plus, but you want to set it up with 4G, which is a bit too bold, plus 4G memory is about the same. So, in the case of 4G memory, don't play these tricks. Otherwise, once you run medium to large software or games that eat memory, you won't run out of memory.

Oh, so you use a 32-bit system and don't want to waste memory that you can't recognize. The 32-bit system can recognize, and the capacity that cannot be recognized can be made into a virtual disk, about 768M.

Can the memory be set? What can be set is virtual memory.

It's still best to let the system assign automatically.

You can see it on the motherboard, it's the size of a dollar coin!

The round thing in this ** is yes.

The location varies from motherboard to motherboard.

The battery is a coin cell battery.

Round, silvery-white.

Look at this**.

In the early mobile phone battery, the T pin was used to connect the negative coefficient thermistor (generally 10K), which was directly connected to the ground of the battery protection board, and did not have any relationship with the protection circuit of the battery. The function of the original design is to calculate the battery level through the change of battery temperature that causes the thermistor to change (the higher the temperature, the smaller the resistance value) (the discharge and charging of lithium batteries are related to temperature), so as to better indicate the power level.

Some of the early batteries also have a D pin, this foot is generally connected to the ordinary chip resistor, Motorola's mobile phone is generally connected to an identification IC, this foot is basically directly to the ground, this foot is used to identify whether the battery is correct, and the current mobile phone battery basically does not use this.

In today's batteries, the T pin is generally directly connected to a chip resistor to the ground, and the resistance value is nothing more than 10K, 100K, and other commonly used ones.

If this foot is charged with a universal charger, it has no effect, and you can't identify it with the original charger, which means that your original charger has such an identification item, and the charger is relatively high-end, at least there is a comparison circuit.

The following is a schematic diagram of the mobile phone battery protection board, I don't know if you can understand it. Notice no, the resistance of the T pin is directly connected to the battery ground.

The charger has three pins, i.e. +-t

It is the positive electrode. It's the negative electrode.

t is the induction line.

It is not a series grounding, it is to induce the signal of the cell, because the battery has already added a protection board, and the function of the protection board: overcharge protection, overdischarge protection, and short-circuit protection!

T is the abbreviation of thermal, which is mainly used to monitor battery and PCM temperature;

There is a thermostat on the PCM in the battery at the T terminal, which is mainly used to monitor the temperature of the battery and the PCM, and transmit the temperature signal to the load controller for processing, if the temperature of the battery and the PCM is too high, the charge and discharge will be prohibited.

"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. In 1912, lithium metal batteries were first developed by Gilbert NLewis proposed and studied.

In the 70s of the 20th century, m s.Whittingham proposed and began research on lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements.

1. Charge according to the standard time (3-4 hours to be full) and program, even the first three times;

2. When the machine power is too low, you should try to start charging in time;

3. The activation of the lithium battery does not require a special method, and the lithium battery will be activated naturally in the normal use of the machine. If you insist on using the circulating "first three 12-hour long charge activation" method, it won't actually work.

4、You should keep the battery high,Don't wait until you run out of power to charge,This will affect the life of the battery 5、Don't use the phone when the battery is charging,It is easy to damage the life of the TV。

Don't worry about the T pin, you just need to connect the positive and negative poles of the battery cell to the positive and negative poles of the protection board, you can also go to the home of the flashlight to search for posts, there are many articles on changing the charger of the mobile power supply.

To redo the system, you only need to format the C disk, and there is no need to format other disks.

Your hard drive has been used for so many years, have you done disk defragmentation on a regular basis?

If not, then the files in your hard disk are stored in a paragraph, one here, one there, the hard disk reads the file is to find it back and forth, the hard disk is very hard, I won't talk about the reading speed, transfer the important files.

Format your hard drive, and it's best to do a bad sector test to see if the hard drive is partially damaged after using it for so long.

Reinstall the system, repartition it.

Then copy the transferred files to a non-system partition (generally speaking, a non-C disk).

You can also add a memory module without a grid, there is no connection, and adding a memory module will definitely be fast. If you want to check, just check C.

The running speed of the computer is related to many aspects, such as the aging of the hardware, the number of running programs, whether there are viruses, etc., generally speaking, you only need to have a ghost to make a system disk, which has the least impact on your files, and once the system has a problem, you only need to restore it, which is currently a more popular and convenient method.

If you don't have important documents, you can make a full use of them.

Disk file fragmentation can affect disk performance. If you don't organize for a long time, there will be more and more file fragments, and the read and write performance of the hard disk will deteriorate. Therefore, it is not a comprehensive approach to just focus on the C drive.

Also, it's not necessarily all the disk's fault that you feel slow. If you win XP, you won't be able to experience what it's like to be refreshing without 1G of memory. Besides, now that the memory has been cabbage price, 1G is not difficult to achieve.

I installed it in 05, Sempemp 2500+ (overclocked 50%), 1G DDR400, Seagate SATA 80G, except for playing games CPU is not enough, other applications do not feel slow.

In the case of no virus, just the C drive is on the line.

Just defragment it.

Full-step formatting, repartitioning, or saving the files you want to keep to a USB flash drive!

CMOS settings,There are a lot of tutorials like this on the Internet.,A look at it will。。。

There is a special protection board with a boost (5V) with charging port, you can use it directly! Pay attention to the magnitude of the current. If a 10Ah battery is connected in parallel, the charging time will be very long, and long-term low-current charging will have an impact on the performance.

Why bother to make it clear, okay? What is it used for, what are the requirements?

It should be possible, what is the output current of your charger? If it is an ordinary mobile phone charger, the charging time can be waited.

Yes, but not just 5vYes, but be mindful of the charging time!
