The computer won t turn on, it s like it s running out of power, and nothing is running

The main unit may not be powered on in the following situations.

1. The power supply is used for too long, which leads to problems with the internal line connection, resulting in no power, 2. The cup capacitor on the motherboard is burned, resulting in no power supply, 3. The memory module is loose, resulting in the line not working

Hello, then charge it and then turn it on.

1. The battery is exhausted; Jian Hui.

2. The battery is aging or has a memory effect, and it cannot continue to last when the power is not exhausted;

3. The battery management software of the computer is abnormal, so that the computer obtains the wrong power information and causes the shutdown;

4. The battery management parameters of the computer are unreasonable, and the battery is shut down when the critical point of residual power is reached;

5. Protective shutdown caused by non-battery factors such as high computer temperature, abnormal software, and virus infection.

Introduction: Notebook originally refers to a paper notebook used to record and write a diary, and now it mostly refers to "laptop computers" and notebook classification browsers. Laptops, also known as "portable computers", are characterized by their small size and are easier to carry than PCs.

Also known as a laptop, PDA, or laptop, it is a small, portable personal computer that usually weighs 1-3 kilograms. The current trend is to be smaller and lighter, but more powerful.

Laptop battery: Rechargeable batteries are commonly used in laptops, and they also provide support for general civilian AC, which is equivalent to providing a UPS with excellent performance for computers. However, whether it can be shared with civilian alternating current depends on the type of battery.

Laptop battery classification:

1. The relatively rare nickel-cadmium battery, this kind of battery has a memory effect, that is, the battery must be completely used up each time and then charged separately, and the charging must be fully charged once before it can be used. If each charge and discharge is insufficient, insufficient charging or improper discharge will lead to a reduction in battery capacity;

2. NiMH battery, this kind of battery basically has no memory effect, and the charging and discharging are relatively arbitrary, so when in use, you can use the computer while connecting the power adapter of the laptop to AC. At this time, if the battery is insufficient, you can use the computer while charging, and if the AC power goes out, the battery can be powered automatically.

3. Lithium battery is the current mainstream product, characterized by high voltage, low weight, high energy, no nuclear answer has a memory effect, and can also be charged at any time; Other things being equal, the same weight of lithium-ion batteries can be supplied for 5 hours longer than nickel-metal hydride batteries, generally more than 2 hours, and some can even reach 4 hours.

The computer host suddenly ran out of power, and in this case, there are generally the following situations next to Huizhao:

1. It may be that the power supply of the host is broken, you can short the power supply of the host, and connect the green and black wires of the plug of the motherboard, if the motherboard can be powered on, it is generally no problem.

2. You can directly skip the switch and try it directly on the switch connector on the motherboard, if it can be turned on normally, the switch of the host is broken, and you can also use the restart switch as the switch chain of the power supply.

3. The motherboard is broken, which is the biggest failure, and the professionalism required is also the most advanced, so it can only be sent for repair or replacement.
