Computers are the most common in our lives, and they are also very important in our work, and they are almost inseparable from the office. In addition, the trend of social development is also towards informatization, so it is very important to be able to use computers. The first thing you need to learn about a computer is to turn it on.

1.Select "Power Management Setup" in the main BIOS settings page to enter the "Power Management" window.

Note: By default, the "Resume by Alarm" option is turned off.

2.Move the mouse over the "Resume by Alarm" item and use the "Page Down" key to change "disabled" to "enabled", and the date and time settings that were originally grayed out will be brightened under the "Resume by Alarm" option.

3.Hover over "Date Alarm" and set a specific date between 1 and 31 with "Page Down".

4.Move the mouse over "Time Alarm" and set the specific time as needed, and the time mode is generally "Hours:Minutes:Seconds:".

5.Save the settings to exit the BIOS.

After that, when the clock in the BIOS jumps to the set time, the computer will automatically start up when the computer is turned off.

1. First of all, you can press and hold the power button for about 35 seconds to use up the residual static electricity inside the notebook, and then wait for five or six minutes, and then press and hold the power button again.

2. Remove the battery of the computer, plug in the external power supply, and wait for about 20 seconds to press the power button to turn on the computer.

3. If it still can't be turned on, and the light of the power adapter will be extinguished immediately, then you should unplug the power adapter immediately, it may be a circuit problem of the adapter, and plugging it may cause the motherboard to be burned out or short-circuited.

4. Unplug the power adapter, install the battery, turn it on again, if it can't be turned on, then take off the battery and send it to a professional maintenance place for maintenance.

1. If the host is not powered on, first check whether the mu spike failure indicator light on the chassis is on, put your hand on the power supply fan port, and see if the power supply fan is rotating, so as to judge whether the host is powered up; If the host is powered on normally, then see if the indicator light on the display is on, if it is on, the display is also normal when it is powered on, and both are normal, then the power supply fault is basically eliminated. Trembling.

2. If the computer host or monitor is not powered normally, please check that the power socket of the computer is in good contact, whether the power cord is broken, and the plug-in family ruler board.

There is no electricity. If it is not caused by the above problems, it may be a problem with the host, and you can ask professional maintenance personnel to repair it at this time.

You can unplug it and check if there is bending, broken needle, and a lot of dirt in the D-shaped socket, which is a problem that many users often encounter. When connecting the D-shaped socket, due to uneven force, or forgetting to tighten the socket fixing screw, the socket is not in good contact, or due to improper installation method, the needle in the D-socket is broken or bent, resulting in poor contact, etc.

3. Open the side cover of the main chassis, check whether the CPU radiator fan and the power supply fan are running, if the fan is not running, then you can basically know the reason, either the motherboard or the power supply problem (if the indicator light on the motherboard is not on, it is a power supply problem).

4. If the CPU radiator fan and power supply fan are running, after shutting down, then we unplug the memory and use the eraser to wipe the memory gold finger.

Plug it in another memory slot and try it again.

5. If there are two memory, it is recommended that you unplug one memory and try to boot it up, if it can't be turned on, replace it with another (single) memory plug in, in case one memory is broken and the computer can't be turned on.

6. You can try to put the button battery on the motherboard.

Discharge (unplug the coin cell battery and install it), and then try to turn it on. If your computer has integrated graphics.

The computer host of independent graphics card, the vast majority of computers at present are dual graphics cards, with screwdrivers.

Remove the discrete graphics card, connect the monitor cable to the integrated graphics card connector on the motherboard, if the computer can turn on, it means that the discrete graphics card is broken.

There are many reasons why HP computers can't turn on, so what are the reasons why HP computers can't turn on?

1. After booting on, the host is normal, and the monitor screen is black.

If the HP computer cannot be turned on for this reason, then you need to check whether the VGA cable between the host and the monitor is connected normally, and whether the power supply of the power core button of the monitor is normal. If there is no problem, find a screwdriver to open the lid of the main chassis, pull off the memory module, and wipe the gold finger area with an eraser; If you don't turn on the computer yet, unplug the graphics card if you have a discrete graphics card; If it doesn't turn on yet, it is likely that the motherboard's hardware is faulty.

2. The computer cannot enter the system after booting, and a hail attack is stuck in the startup.

The computer has been booting since the open source brother machine, and it can't enter the system interface, so at this time, it is likely that there is a problem with the system. This requires pressing F8 all the time after booting up, and when a selection screen appears, select the option "*Configure correctly at one time" and restart the computer. If it still doesn't work, it is possible that the system files are corrupted, so reinstall the system.

3. After powering on, the cursor in the upper left corner of the monitor keeps flashing.

HP laptop has this fault, you need to go into the BIOS to set the hard disk to * boot item; If it doesn't work, then change the hard disk mode in the BIOS; If it still doesn't work, insert the USB flash drive boot disk into the PE desktop, repair the boot file again, and reinstall the system if it still doesn't work.

4. After the computer is turned on, the system has been self-checking.

After the HP computer is turned on, the computer system has been in the self-test state, which means that a certain area of the hard disk has failed. At this time, reboot, when the system reaches the self-test interface, quickly press the space bar, that is, the key on the keyboard *long, at this time, the self-test will be skipped, and the system will be entered.

The problem that the computer cannot be turned on with a black screen is generally caused by the oxidation of the memory and graphics card, resulting in poor contact with the memory slot or graphics card slot, and the number of skins causes the computer to be unable to turn on and the black screen. At this time, turn off the power supply, open the back cover of the notebook, take out the card slot of the memory, if it is not a separate graphics card soldered to the motherboard, also take out the card slot to burn which one, and use an eraser to align the part of the memory and the gold finger of the graphics card.

The desktop computer can not be turned on, you can first check whether the socket is normal, check whether there is a loose contact, if the contact and socket are fine, it may be a problem with the computer power supply, the power supply can not be supplied to the lead electricity, naturally can not open the grinding machine.

According to the survey, consumers in the region prefer products with better brands, and laptops are more popular with consumers than desktops. Therefore, in the development of computer sales in the region, two to four types of computers with better brands should be monopolized, such as Lenovo, Asus, HP, Dell, etc., and the models should be mainly notebooks, with some desktops;

Eliminate computers, do not turn on bad computers, all kinds of computer accessories ten years of professional experience, door-to-door ****: Apple products, notebooks, desktop office equipment: **desktop computers, laptops, all computers**! Good and bad! Free door-to-door!

Hardware upgrades, (whether it is a desktop or a notebook, it can greatly improve the speed of turning on and off the software of the computer, especially when the mouse has been turning around when it is booted and opened the software).

1. The computer host is malfunctioning. Faults such as damaged power supply, excessive overclocking, and incorrect CMOS settings on the motherboard will cause the problem of black screen cursor flashing when the desktop laptop is booted, so it is important to eliminate these problems first.

Need to often work in the outer code inspection, although the unit has a desktop computer, but the desktop computer equipment is inconvenient to carry, for a bid to buy tens of thousands of yuan of laptops, the use rate is really not high, with a few hundred yuan to temporarily rent an IBM laptop should be more appropriate. The unit does program development, recruits a new batch of salesmen, the salesmen are more mobile, and most of the business units outside to run work, leasing laptops should be more suitable. School is about to graduate.

We have to determine whether the computer is powered on normally, if it is powered on normally or the virtual machine is not opened, it may be that there is a problem with the hard disk, and the hard disk is still not working after replacement, then the head of the slide is a problem with the computer screen, which needs to be repaired to make the socks burn able to deal with it.

6.If it is confirmed that it is not a problem with the keyland software, then it is likely to be a hardware problem, and the first thing that should come to mind is memory. When using a desktop, our computer can't be turned on, and we will unplug the memory and wipe it on it, and the notebook can also do this kind of operation, but compared to the cavity bright, it is inconvenient to disassemble the notebook purely in the desktop, and it is not easy.

HP desktop computer won't turn on, why? If the HP desktop computer can't be turned on quickly, you can open the computer case, pull out the memory module, wipe the contact points of the cable with the burial resistance, and then reinsert the liquid into the postponement to boot the computer.

There are many reasons for this, both software and hardware. If you don't have any experience, it's best to look for a professional.

1. Reinstall the power adapter

At this time, you need to remove the battery and the power adapter, press and hold the switch button for 30 seconds to discharge the static electricity, wait for about 15 minutes, and then connect the power adapter separately to power the machine.

2. Remove the memory card.

HP laptops won't turn on, and it may be caused by oxidation of the laptop's memory and graphics card. At this time, you need to open the back cover of the notebook, and then take out the card slot of the memory, if it is not an independent graphics card soldered to the motherboard, also take out the card slot, aim at the part of the memory and the gold finger of the graphics card, wipe it back and forth with an eraser, clean it up and insert it back in, and cover the back cover.

3. Change the connection wire.

Another reason why your HP computer won't turn on is because of a problem with the cable, which causes the computer to not connect. At this time, you can try to reconnect a line, try to reconnect the computer cable, and replug the hardware cable in the computer case on the motherboard.

4. If the computer fails, it is recommended to send it to a professional repair shop for professional disassembly and repair.

Troubleshoot the LCD screen

1. In addition to excluding non-motherboard and graphics card failures, it is a common LCD screen failure. If something is faintly displayed, it means that the LCD screen and cable are not damaged, and it may be that the backlight is not lit.

2. There are two reasons why the backlight cannot be lit: the backlight tube is burned out or the high-voltage circuit driving the lamp is damaged. The working principle of the high-voltage circuit board is to convert the low-voltage direct current provided by the motherboard into high-frequency and high-voltage electricity through the switching circuit, and light up the backlight tube.

3. If the backlight can't be lit, you can just press the power button to start when you put your ears on the screen frame and listen carefully, if there is a sizzling sound, and then it will be silent, which is roughly the problem of the high-voltage circuit board, if it has been silent, it may be a problem with the lamp.
