If you discover that your Lenovo laptop has stopped turning on, the operating system will not load, or there is some problem with the indicators, then before calling for repairs, rule out the most obvious reasons, which you, depending on your skills, can fix on your own.
Problems that may cause your Lenovo laptop to not turn on:
- power button;
- battery;
- nutrition;
- wire;
- connectors;
- cooler;
- video card;
- RAM;
- hard drive;
- motherboard;
- screen;
- BIOS and OS.
Serviceability of the power supply, cords, connectors, power button
When faced with the problem that your Lenovo g580, g50, g500, b590, g505, b560, g585, b570e, Ideapad 100 laptop does not turn on, first check the serviceability of the power supply, cord and connection connectors. The power button can also cause the device to not respond when turned on.
Visually inspect these elements - they should not have external damage. If possible, perform a performance test on another device or connect a similar power supply.
External negative impact
A black screen when you turn on your Lenovo laptop or there is no reaction at all to turning it on - the indicators do not light up - this may be due to a fall/impact of your device or liquid getting on it. Both of these factors have an extremely negative impact on his ability to continue working.
It is best to immediately, especially in the case of liquid ingress, contact Lenovo laptop repair specialists, where they will take measures to eliminate the consequences and carry out diagnostics.
Constant reboot, operating system problem, BIOS failure
Depending on the malfunction that occurred with your device, the defect “Lenovo laptop does not turn on” manifests itself differently.
So, if it still responds to being turned on, but immediately turns off, this is a problem with the cooling system. How long has it been since you cleaned and replaced thermal paste? Thus, the system prevents failure of more serious components due to overheating.
If the device turns on, but does not boot, then this is a problem with the Windows operating system or the basic BIOS system.
The latter fails extremely rarely and in this case the amateur is not recommended to reinstall it himself. But Windows OS could crash if it shut down incorrectly or if an unlicensed version was used. Having the installation file, you can easily reinstall it yourself.
Lenovo laptop does not turn on, black screen and indicators do not light up
More serious problems that led to the fact that the Lenovo g580, g50, g500, b590, g505, b560, g585, b570e, Ideapad 100 or other models laptop does not turn on is the failure of vital elements for it: video card, RAM memory, hard drive, motherboard or screen.
If, when you turn on your gadget, you hear a reaction (the cooler starts up, the characteristic sound of the OS starting up), but there is no image on the screen, there is a problem with the video card or screen (matrix).
The hard drive problem is detected by the system and a corresponding message is displayed on a black or blue screen indicating a critical operating error.
The HDD itself rarely breaks down. This is often preceded by a fall or intense shaking of the device.
The laptop will notify the user about a failed RAM block with a special sound signal. This means it needs to be replaced.
The most severe breakdown for the owner is the failure of the motherboard. As a rule, repairs often do not give long-term results and in the end it all comes down to the fact that the board needs to be replaced with a new one. In most cases, this is an expensive component and replacement will not be cheap.
Recommendations for maintaining the life of a Lenovo laptop
Careful and careful handling of equipment significantly extends the service life declared by the manufacturer.
Avoid mechanical impact on the laptop: intense or severe shaking, falling or impact will lead to failure of the internal components of the device.
Avoid contact with liquid or high humidity in the air. Oxidized contacts can lead to short circuits and costly repairs.
Perform regular mechanical, thermal paste replacement, and systemic virus cleaning. This way you prevent the device from overheating and incorrect operation of the OS.
Computers are eternal mysteries for users. It is very difficult to predict whether a particular machine will actually work properly for a long time. No one is immune from failures and malfunctions. What should you do if you find that your Lenovo laptop won’t turn on? Why might this happen? The best tips and tricks will be presented below. Understanding all this is not so difficult if you use the method of elimination. Quite often, users immediately take the laptop to service centers. There is no need to do this. It is likely that the problem can be resolved without outside help. So what options are there?
No battery
Lenovo laptop won't turn on? It is likely that the device simply does not have a battery. This situation is relevant when it comes to working with a device without connecting it via a wire to the network.
Correcting the situation is easy and simple. It is enough to insert the battery into the laptop, into its lower part. The user will see a special niche on the panel. The missing part of the laptop is inserted into it. You can then resume using your device. No results? Don't despair! There are still a lot of options!
Battery charge
How to turn on a Lenovo laptop if the battery is inserted, but the device still does not want to work? It cannot be ruled out that the battery has no charge. In this case, you will not be able to work on a laptop without additionally connecting it to the network.
It is enough to connect a special power cord to the machine and then plug it into a power outlet. And then - wait a little. The light on the front panel of the laptop should light up indicating the battery charge. A little wait (usually a few hours) - and you can work with Lenovo without additional wires. True, until the battery runs out again. As practice shows, an average charge lasts for 4 hours.
Nutrition
The next reason is somewhat similar to the situation with a laptop battery. Laptop refuses to turn on? It cannot be ruled out that there is no connection to a power source in principle. Why is this schedule highlighted as a separate item?
The fact is that some Lenovo laptops are equipped with a built-in battery. It is located under the bottom panel and cannot be removed easily. In this case, it is recommended to find the power cord and plug it into the network. And then connect it to the device.
If there is no power, the machine will turn on and work. Still no progress? Doesn't turn on What other situations occur? How to deal with them?
Wires
For example, the whole issue may be a damaged power cord. Such situations are especially relevant for older laptops. Or if the device's power cord is frequently used/pinched/exposed to external influences. It is very problematic for the user to diagnose such a problem.
If there is a similar power cord, it is recommended to connect it to the laptop and then try to turn it on again. Otherwise, it is better to take the device with all components to the Lenovo service center. They will quickly help you sort out the problem.
Another alternative solution is to purchase a new power supply cable for a laptop of a particular model. The new component will 100% work. Accordingly, the computer will turn on. But what if there is no progress even after replacing the wire?
Laptop connectors
Lenovo laptop won't turn on? What to do in this case? When all the previously listed options have been excluded, you will have to pay attention to other nuances. Let's say, on the connectors for connecting power to the device.
The fact is that sometimes the sockets on laptops get damaged. This reason is practically excluded on new computers, but is more common when it comes to older devices.
The Lenovo service center helps fix the problem. They will not only help you understand whether the problem is really with the connectors, but will also fix them. Only in some cases will you have to buy a new laptop.
Video card
What other options might there be? All the previously listed scenarios are very common phenomena. But they are quickly excluded. What to do if the Lenovo laptop gives out? It is important to pay attention to what is happening to the device as a whole.
For example, when the cooler is running. And it’s normal - it doesn’t make loud noise, it performs its functions. In fact, the laptop turns on, but there is no image on the screen. What to do then?
It's worth checking the video card. It is likely that it is faulty. A black screen instead of a computer or laptop being turned on is a quite common occurrence when Unknowing users are better off using the services of a Lenovo service center to test the theory. After all, you can easily damage the remaining components of the laptop. After repairing or replacing the video card, the problem should go away on its own.
RAM
Lenovo laptop won't turn on? What to do? A similar situation cannot be ruled out due to an equipment conflict. For example, video cards and RAM. Or the RAM has broken down altogether. Relevant for old laptops or those that have been modified to one degree or another. Especially when the user independently went through the hardware of the device.
As a rule, if the problem lies in the RAM, the laptop will emit a certain signal when turned on. It is impossible not to hear him. Everything can be solved either by repairing the laptop (the computer is taken to a service center, then the working gadget is taken away), or by purchasing a new device.
BIOS
What circumstances can affect the performance of Lenovo? There are many reasons for this problem. And identifying them on your own is not as easy as it seems. What to do if the Lenovo laptop does not want to work? The monitor does not turn on, although everything is fine with the hardware, the power cord, connection connectors, and the battery are also normal. Why are problems not eliminated?
It is likely that the whole point is in the design of the computer system. A faulty or damaged BIOS quite often brings a lot of problems to users. In this case, the computer may not turn on, simply reboot, turn off on its own and not save what was done while working with the device.
The only thing that helps here is reinstalling and reconfiguring the BIOS. This is usually done by system administrators, as well as service center employees. It is not recommended for the average user to mess with the BIOS on their own. It is possible that an ineptly carried out reinstallation will turn a Lenovo laptop into a pile of useless metal. Fortunately, this happens extremely rarely.
Hard drive
It also happens that, despite the fact that the laptop or OS constantly reboots. Then you need to make sure the hard drive is working. If it is missing or in a faulty condition, there is nothing to be surprised about. In fact, the gadget works, but there is nowhere for it to load the operating system.
An extremely rare occurrence. It can be easily diagnosed by contacting service centers. In this situation, the laptop needs to be supplemented with a hard drive that will work properly. The operating system is installed on it, after which a second attempt to work with the device occurs. Everything is fine? Then you don’t have to worry about the integrity of the laptop and its further operation. Still no result? Lenovo laptop won't turn on? Other situations cannot be excluded. Which ones specifically? What else is recommended for users to pay attention to?
Turned on and off
Sometimes a computer or laptop turns on and then turns off. Or it constantly reboots. There is no need to be afraid of such circumstances. You need to pay attention to the operation of the cooler. Is it not working or is it functioning normally?
In any case, if a Lenovo laptop (or any other) starts to turn off spontaneously or reboots constantly, you can come to the conclusion that the culprit is simple overheating of the equipment.
It occurs for various reasons. One of them is a clogged cooler. Any laptop needs to be cleaned from time to time. And the cooler of the device too. It is necessary to take all possible actions to eliminate overheating. For example, clean the fan or replace it altogether. It is also worth paying attention to the position of the computer - the laptop should not be positioned in such a way that access to oxygen in the cooler area is blocked. All this will help restore the functionality of the gadget.
Screen
Sometimes the problem is a faulty laptop display. Theoretically, it will work, but the user will never see the image. If we are talking about damage to the display, then a new screen must be installed on the Lenovo laptop. This is done only in service centers. And this is not always the case.
Most often, if the display malfunctions, you just have to buy a new laptop. And it doesn’t matter what company the device was - Lenovo or ASUS, for example. The main thing is that the reasons for failure are the same for all laptops.
Now it’s clear why the Lenovo laptop doesn’t work. the system reboots or any other gadget failure is observed - different situations were considered. The help of service centers in such situations is not always required.
Question: Lenovo g500 laptop hangs on the manufacturer's logo.
Hello. I have a lenovo g500 laptop. Such a problem happened, it began to hang on the logo, every time it was turned on. This started happening after the update.

Does anyone know what to do?
Answer: alexeyvg, there is a button, but it’s of little use, you press it and the laptop freezes on the logo, just like when you turn it on. I tried through the recovery system, it was successful, but the problem remained.
Question: Lenovo G500 does not turn on
Good afternoon. This is the problem: I have a Lenovo G500 laptop (59-391955), a few days ago I installed Windows 10 on it (licensed, not pirated), everything worked more or less stable, sometimes a critical error occurred (the start menu and Cortana did not work) and required a reboot . In the evening I turned off the laptop without any problems, in the morning the laptop turns on, but the Lenovo message appears and no further loading occurs. I put the RAM in different slots, the BIOS does not open.
What could be wrong with it and how to fix it?
Answer: Managed to launch. I pressed the BIOS download button, again there was a screen with the inscription. I pressed Ctrl+Alt+Del a couple of times and windows loaded, all the files are in place, everything works.
Question: Lenovo G500 (LA-6931P rev 1.0) Does not boot from disks in UEFI mode, everything works in Legacy.
They brought in a Lenovo G500 (LA-6931P rev 1.0) laptop for repair with a malfunction - it won’t turn on. An autopsy and a quick inspection revealed a hole in the multi and a burnt matrix cable. During the diagnostics, an audio codec and SLJ8E hub were added to them.
After replacing all of the above (the hub installed SLJ8C, there are no others available now) and updating the firmware of the cartoon, the book started up, but it turns out that 7 in Legacy mode boots and works fine (the only thing after installing the firewood on the atish video was a blue screen, but switching in the BIOS on UMA and the beech boots normally).
And when I insert a disk with 8 or 8.1 and transfer the beech to boot in UEFI mode, when loading the beech it says that it does not find a boot device, while in UEFI mode the boot proceeds normally from the drive and USB flash drive.
The BIOS was sewn into a cartoon merged from the old cartoon on this board, the main BIOS was also sewn with a verified dump. What should I look at and can a new hub or a half-dead BIOS chip mess up like this?
Answer: I uploaded an image cut from the off-BIOS into another flash drive, but it still doesn’t want to load.
I rolled 8.1 onto a blank disk in UEFI mode - everything loads and works. There is no original disk included with this beech, but there are several other Lenovos with 8 or 8.1 disks for repair from the same client, but this beech doesn’t want to work with these disks in UEFI mode, it’s not clear why.
As soon as I test the beech I will close the topic.
Question: Lenovo G500 (LA-9631P) Bios crashed.
Hello)
Lenovo G500 laptop, LA-9631P platform.
flash drive - cFeon QH64-104HIP
cartoon - KB9012QF A4
Bios crashed. According to the owner, they reset the BIOS settings to default, saved the settings, and after that the image disappeared.
I unsoldered the flash drive, made a dump just in case, uploaded a known working dump with a clean ME - the laptop started, and upon boot it showed "EFI Network 0 for IPv4 (Mac address) boot fallen"
BIOS line
Product Name - INVALID
Lenovo SN - INVALID
If you make any changes to the settings and save, then after a reboot you get a black screen. and it only helps if you flash the BIOS again with the programmer.
What could it be? Or am I doing something wrong?
Answer:"The graphics are switchable by default. UMA mode can only be turned on manually." I completely agree with the statement. And you try to flash it into another, known working flash drive. Maybe it will help.

Question: Lenovo G500 screen does not turn on immediately
Hello,
There is a laptop Lenovo G500 8GB RAM, 500GB, i3 2.4 GHz
I’ve been using it for almost a year and a half, I miss going to work, going to university and using it at home. Mainly PHPStorm, Chrome, etc. software I almost never turn it off, I just close the lid (sleep mode, not hibernation). Windows 10 OS, I rarely reboot, mainly when updates require a reboot. My problem: About a month ago, the laptop started not turning off. I turn it off, the “Shutdown” message is displayed and after that the screen turns off, while the laptop is still working, the coolers are spinning and it can sit like that for an eternity, I tried not to touch it, it just doesn’t turn off. So I press the power button. After that, if you turn on the laptop, it will start, but the screen does not light up and I tried to wait, but just like when turning it off, it just stands there, after a while the coolers start spinning and that’s it. I tried many tricks and seemed to have found a method. I forcefully turn off the laptop, close the lid for a while (varies from a couple of minutes or more) and then open the lid and turn it on again. Sometimes the laptop starts normally, the screen lights up, etc. I also tried removing the battery for a while (also from a couple of minutes or more) and then turning it on again, sometimes it turns on, sometimes it doesn’t. I even reinstalled Windows, but that's not the problem. I also have a 2nd monitor, if that can have any effect. In cases where the laptop screen does not light up even with a monitor connected, the system still does not boot, the laptop just works, heats up as if it were working.
And yet, if you restart the laptop while it is on, it also does not turn off completely, or it may turn off but the screen does not show anything. What could be the problem? Maybe someone had something similar? I tried to describe the problem in detail, I hope there is a solution.
Answer: ZZZ7ZZZ,
