BQ computer mining

1. Desktop computers have the advantages of rability and affordable price. Compared with laptops, they have better configuration and better heat dissipation at the same price. If the accessories are damaged, the replacement price is relatively cheap. The disadvantages are: bulky and large power consumption. Computer is a kind of machine that processes data according to a series of instructions by using the principle of electronics. Computer can be divided into two parts: software system and hardware system. The first computer ENIAC was born on February 14, 1946< br />

2. Bq28400 (not recommended in new design)
network notebook and writing board, lithium-ion battery power monitor and protector
description
bq28400 device is a fully integrated battery power monitor and analog monitoring management solution with a single tssop package, which can provide protection and control for two series Cell Lithium-Ion battery pack
Supplier: paimingxincheng components mall www.iczoom.com
by achieving the optimal balance between monitoring and control based on fast response analog hardware and an integrated fast CPU, an ideal pack based or in system lithium-ion battery solution is created. In addition, bq28400
also provides flexible user programmable settings (stored in flash memory) for controlling key system parameters such as over-current, short circuit, under voltage / over voltage and over / under temperature conditions
bq28400 communicates with the system host through an interface compatible with the two-wire SMBus 1.1 specification, thus providing high accuracy report and control of battery pack operation. FET driver and
tssop package realize the solution of low cost and small footprint, as well as simple layout and wiring on narrow battery pack PCB<

3. From your description, it should be that the system file is missing. If it can enter the system normally, you don't have to worry about it, otherwise you have to consider reloading it.

4. Unknown_Error

5. The harm of this virus is that after the virus runs, it can infect the virus file to the system directory and automatically run the item to randomly boot the virus body. The main behavior of the virus is to delete all files of the user's extended partition and blackmail the user
solutions; 1. If you are infected with the virus, you can use anti-virus software to kill it, such as Tencent computer manager's cloud intelligent killing. If the killing is not clean, you can kill it in safe mode. Restart the computer, press F8 to enter safe mode, you can kill the virus, and you can completely kill the virus
2. Now virus prevention is the most important thing. Installing a better antivirus software can prevent viruses, such as Tencent computer housekeeper, Dongfang weidian, Kaspersky and so on. Turning on intelligent protection can prevent viruses.

6. The causes and solutions of computer crash are as follows:
1. Computer system security, viruses or Trojans in the computer, may cause the computer to restart or crash
solution: you can use network guard and network antivirus to repair the computer
2. Computer hardware failure, such as: mainboard capacitance leakage, memory mole damage, memory mole incompatibility, hard disk failure, CPU overheating and other failures
solution: non professionals suggest sending them for repair
3. Computer software failure, such as interruption conflict, incorrect software configuration, incorrect system configuration, etc
solution: the system can be reinstalled or the computer can be repaired with network guard and network antivirus.

7. The general reasons and solutions for not finding Bluetooth: first, it is generally believed that after Bluetooth is turned on, the mobile phone can find Bluetooth and successfully connect with it. In fact, this is wrong. If a mobile phone wants to search for Bluetooth, Bluetooth must enter a special state: pairing state. 2、 Specific operation steps: 1. Confirm that Bluetooth is in the off state: long press the multi-function key for 2-3 seconds, and the Bluetooth indicator red light flashes rapidly for about 3 times, that is, turn off Bluetooth. 2. Bluetooth enters pairing state: long press the multi-function key for 7-8 seconds, Bluetooth enters pairing state, showing that the red and blue colors flash alternately or the indicator light is always on. 3、 After Bluetooth successfully enters the pairing state, the next step is to enter the operation of the mobile phone: 1. Turn on the Bluetooth function of the mobile phone and search for the model of Bluetooth. 2. When the mobile phone is connected with Bluetooth, if the pin code is prompted, it is usually 0000 or 1234. 3. The match was successful. At this time, you can use Bluetooth to answer and make calls. If Bluetooth supports A2DP protocol, it can also be used to listen to music.

9. Hello, when the battery is fully charged, the computer will automatically stop charging, which will not cause overshoot
as long as the AC power is plugged in, it is power supply
it is recommended that you plug the power into the notebook, so as to prevent sudden power failure, causing greater damage to the computer and data loss. It is recommended that the battery be fully charged and discharged once a month
I hope it can help you
