Anonymous users2024-02-15Hello, the laptop can't turn on the processing :
1. The power supply of the notebook is insufficient; This situation is caused by excessive use of the laptop or excessive power consumption of the battery that has been standby for a long time, and as long as you charge it more before use, this problem will be solved.
Second, there is no reflection when the machine is turned on; This type of situation is generally caused by loose hardware or water ingress into the notebook. If the hardware is loose, just open the notebook and reinsert the loose hardware; However, if it is caused by hardware damage, the hardware should be replaced after testing with a professional instrument.
3. When the machine is turned on, it prompts that the serial port, parallel port, hard disk, etc. cannot be recognized; This type of situation is usually caused by loose hardware or the same error of COMS data, and can only be troubled by reinserting the loose hardware and restoring COMS data.
Fourth, the computer cannot enter the system after the alarm is turned on; Whenever the computer starts up, it sounds "Flute." The alarm sound of the "flute" is caused by hardware error or damage. This kind of fault needs to be repaired according to the different alarm sounds.
5. Operating system problems. This type of problem is always reflected in a system boot error or reboot after the hardware detection is completed, and the solution is to restore the system or reinstall the system.
If it doesn't help you, please keep asking!
It's not easy to answer the question, your question is the driving force for me to move forward!!

Laptop batteries are batteries inside laptops, and now the use of rechargeable batteries is one of the advantages of laptops over desktops, which can greatly facilitate the use of laptops in various environments.
The first batteries to be introduced were nickel-cadmium batteries (NIMDs), but they had a "memory effect" that had to be discharged before each charge, which was inconvenient to use, and was soon replaced by nickel-metal hydride batteries (NIMH), which not only did not have a "memory effect", but also increased the power per unit weight by 10 %.

Why can't my laptop turn on with the battery, remove the battery and connect it to the power supply, can it be turned on, will the battery be broken?
How long has it been since the computer turned on?
For daily use, is the battery fully charged, and still plugged in the power to play?
Well. Playing with the laptop like this for a long time will lead to a shorter battery life.
Try to unplug the power supply after a full charge until it is time to recharge.
Just reconfigure the battery
So why can I turn on the battery after pulling it out, and reinstall the battery, the battery is nothing, and it can be used? Is it a battery issue?
At the moment, it's a battery issue.
You unplug the battery, charge it directly with the power supply, and you can turn it on.
It can be turned on by charging directly with the power supply. Mine is a Lenovo G13 that I bought in 410. Go to buy a battery? Is it reliable online?
It's best to check out the brick-and-mortar store.
The battery life of a laptop is about 5 years.
It's not like a motherboard, memory problem, right?
It has nothing to do with the motherboard memory.

This is the first thing to check whether the battery and the notebook are in good contact, if the contact is not good, although you can read the communication data of the battery, you can not charge the battery, at this time you can take out the battery and test the machine more, insert the battery into the computer If you hear a beep, you can think that the contact has been good, try a few more times, you can rule out the problem of poor contact between the computer and the battery, especially when using IBM computers, pay attention to this problem. If it is confirmed that the contact between the battery and the computer is good, but the battery still cannot work normally, then it is possible that the battery itself has a quality problem, and the possibility of the problem is twofold: first, the circuit board of the battery is damaged or has been short-circuited protection; Second, the battery produced by the company may not match the computer you use, incompatible, please correct the battery, or you can come like this, you put you and the battery to someone else's book to try it, to see if this is the case, there will be more relevant information about the use and maintenance of the battery Jimo, I hope mine can help you.
If you have a power supply, you can leave the battery unplugged, and if you keep it plugged in, it's fine, but the battery will be charged automatically. Your laptop can last for hours on a charge, which is pretty awesome, and I haven't heard of it last a few months after charging.
In fact, the battery can still be used now, but your battery must be longer, so the computer self-test chip will indicate that the battery needs to be replaced. I bought Dell in 2006 >>>More
