The computer was struck by lightning ,,, couldn t access the Internet

Whether you use the router or directly use the cat to surf the Internet, if it is a cat and suspect that the cat is broken, you can try to power off the cat first and then start it, can it be solved.

If it's a router, if you can't get the IP in the case of automatic acquisition, then you can restore it to the initial state, that is, power off first, press and hold the reset key, and then power on, release it after 5 seconds, that is, restore the initial, and then you set it again, if you can't, check the hardware, and be ready to spend money to buy the device.

Then you have to consider whether there is a problem with your network card?

Can I get an IP address with auto-acquisition?

Most of them are problems with cats or routers, if it's a problem with cats, try changing cats, if it's a problem with routers, change the jack or change the router.

It's just that you can't get on the network, that is, the chip is not broken, and the network card on the board is right? Change a good PCI NIC. You can't manually set the IP because there is a problem with the network card.

Personally, I think it may be the problem of the cat or the routing as mentioned above? If the network card is fine, check to see if the other hardware is damaged.

The switch port you're using may be broken too!

Curious to ask: How do you know if your computer has been struck by lightning?

After manual setting, I still can't get online"

Can you ping another machine or your gateway?

If it can be a problem with the router (gateway device), if not, it must be a connection problem!

Is your cat's adsllink light always on? If not, the cat is broken.

Check Check your network card and router or cat.

The cat was chopped, depressed, let's change it.

It's not rotten, what's the brand of your computer?

If your computer is struck by lightning, it can cause damage or malfunction of your hardware or software. Here are some possible workarounds:

Check whether the computer hardware is damaged: You can check whether the computer motherboard, power supply, memory, hard disk and other hardware have been damaged. If there is damage to the hardware, the damaged parts need to be replaced or repaired.

Check if your computer boots: If your computer boots up but something goes wrong, you can try to enter safe mode or restore your computer using System Reset. If the computer won't boot, you can try to repair the system using a Windows installation disk or recovery disk.

Fix corrupted files: If there is a problem with your computer's software, you can try to use a disk check tool or data recovery software to repair the damaged files.

Prevention of lightning strikes: In order to avoid the computer from being struck by lightning, it is recommended to use line protectors, UPS power supplies and other equipment to protect the computer.

If none of the above methods can solve the problem, it is recommended to contact a professional computer repair service or consult the technical support of the computer manufacturer.

It is possible that the thunder will break the computer in two cases.

One is through the power line, and the other is the signal line (network cable). Now there are lightning protection measures in residential buildings or suburban houses, and it is rare to break the home appliances through wires, and the power protector will induce a thunderous voltage, and jump off the power at home in advance. The signal line is much easier, and sudden thunder and lightning will produce a strong induced voltage, similar to a pulse, which will damage the internal parts of the computer, ** and other communication equipment within the induction range.

If your router does not have lightning protection, it is best to turn off the computer during a thunderstorm in summer and pull out the network cable (although the power supply is cut off, but the network cable is not unplugged, the pulse generated by the thunder induced voltage can still impact your computer through the network cable). Therefore, the cable TV in some families is obviously unplugged, but the closed line is not pulled out, and it is still damaged by lightning.

If the lightning protection effect of your router is very good, whether it is the power supply or the network cable, then don't play, because sudden thunder will often temporarily turn off the power supply at home, so that the computer will lose power, if this is done frequently, the internal parts of the computer may also be burned.

Although the probability of a computer being struck by lightning is very low, if it does happen, we can use the following points to determine it. The first is that it can't be turned on, and the second is the problem on the motherboard. If the lightning strike voltage is too high, the motherboard damaged by the lightning will be unable to withstand the motherboard original and even the PCB will be broken down and burned out, just learn about it with me!

What are the chances of being hacked while playing with thunder?

Generally speaking, the damage to the computer in a virtual thunderstorm is minimal, mainly because the power supply in the building is generally protected by lightning, and the network is also equipped with lightning protection. Even in the house and with the wireless network, due to the many lightning protection and lightning protection devices around, it will counteract the lightning damage. If lightning strikes, or enters the building through the power line or network line, and destroys the electrical appliances, then the household's TV, refrigerator, and other electrical appliances will be affected, so don't worry too much about the use of your laptop.

What should I do if the computer is struck by lightning and can't be turned on?

The damage of the computer is not covered by the warranty, so when you encounter this kind of problem, you can turn on the computer to see if the power supply is still turning, now the general power supply has power protection to prevent your motherboard from being burned, the old-fashioned power supply is not necessarily, the power supply is turned, the motherboard light is not on, the motherboard is generally the capacitor is easy to be burned, the motherboard, graphics card, CPU is not burned traces, blackened is estimated to be burned. If the main engine light can be lit, see if the display is burned, and the monitor light is still on. If you can't judge the situation, you can say to the after-sales service, let the after-sales service check, if the computer is more serious by lightning, it is recommended to buy a new host.

Thunder mobile phone charging will not be fine.

To be exact, thunder cannot be charged. Thunder and lightning are powerful flashes of light formed by the collision of positive and negative charges in clouds, accompanied by a roaring sound, which produces thunder and lightning. The voltage of lightning is about 100 million volts, and the maximum current can reach 300,000 amps.

Disassemble the chassis panel to see if the hardware is broken down, whether the power supply can run, the easiest is to send it for repair, and you have the foundation to eliminate specific problems with the elimination method.
