Owners of laptops and computers often face a similar situation. When turned on, the motherboard manufacturer's logo is displayed and then nothing happens. Then, if you wait a few minutes, the “Boot device not found” error often appears.
In this article we will tell you why this happens and what you can try to do yourself to solve this problem.
Causes
First, let's figure out why the Lenovo laptop does not turn on and only the splash screen is visible. The appearance of such a glitch can be caused by the following situations:
- RAM shortage;
- software conflict or driver incompatibility;
- laptop overheating;
- negative effects of viruses;
- hard drive failures;
- BIOS problems;
- hardware malfunction and others.
These are the main reasons why a Lenovo laptop does not boot beyond the logo and does not turn on. In such a situation, do not rush to take your computer for repairs, because many problems can be fixed on your own.
Troubleshooting
First of all, make sure the power supply is fixed. If you hear a slight whistle or click from the external or internal power supply when you turn on the PC, the power board is most likely burned out. Now, instead of the required 4-6 amperes, the unit produces 1-3 a.
A typical “symptom” is that the device seems to start turning on, the LEDs on the case light up, the hard drive starts, but after 1-2 seconds the equipment turns off.
Remember if there were any voltage surges in your network. Due to constant operation at high temperatures, the capacitors in the unit could “swell” - then you won’t have to change the entire module, just install new ones.
What to do if only the splash screen is visible
Now let's look at the instructions on what to do when a Lenovo laptop does not boot beyond the splash screen. If the device does not turn on, start with simple steps, and then move on to more global solutions.
Please note the error
If there are any malfunctions, text may appear at the bottom of the screen to show the user the progress of the test. If the survey is successful, the field remains empty. If an error occurs, it appears and informs you about the problem. With its help, you can understand what exactly led to the malfunction. Just copy the link and paste it into a search engine.
Remove the flash drive
If your Lenovo laptop won't boot past the logo, check to see if there is a USB drive installed. Before loading, remove the flash drive from the connector and check whether the device turns on or not.
Open and close the CD/DVD drive
A common situation when a Lenovo laptop freezes and only shows the splash screen is a problem with the SD/DVD drive. This is explained by the fact that at the moment the system boots, the operating system begins to poll all devices and starts with the drive (its opening and closing). If this does not help, and the laptop still does not turn on, try disabling the HDD in the BIOS.
Reset BIOS settings
One of the reasons why the laptop does not boot beyond the Lenovo manufacturer's splash screen is a malfunction in the BIOS. To fix the problem, try resetting your device to factory settings. The algorithm is like this:
- Enter the BIOS at boot time by pressing F2 or F1.
- In the Exit section, find the Load Setup Default item.
- Save your changes and exit by pressing the F10 button.
Wait for the reboot and check if the Lenovo laptop turns on or if it also does not start after the splash screen.
If it is not possible to reset the BIOS using the method discussed above, remove the battery from the motherboard. To do this, disconnect the device from the network, remove the battery and get to the motherboard. Here, remove the battery for a few minutes to reset.
Check the hardware
The cause of the freeze may be poor contact between different elements of the laptop and the motherboard. As a result, only the splash screen is visible upon startup. To check, do the following:
- Disconnect the device from the network.
- Remove the battery.
- Remove the screws that hold the back cover in place.
- Pay attention to the RAM and the quality of its installation. The plank should not be skewed.
- Disconnect the hard drive and plug it back in. At the same time, monitor the quality of the contact connection.
- Pay attention to the keyboard. Perhaps some object got inside and is pinching one of the buttons.
- Enter the BIOS and make sure that the hard drive is set first as the source for booting the OS.
After that, check whether the device turns on and whether the screen saver stage is completed.
Find the faulty peripheral device
If the Lenovo sign still lights up and the laptop does not turn on, disconnect the peripheral devices, and then try connecting them one at a time. As noted, most often the cause of the problem is the CD/DVD drive. In this case, the algorithm is like this:
- Shut down your Lenovo laptop and remove the bottom cover.
- Disconnect the hard drive, CD/DVD drive and other peripherals.
- Leave only one stick of RAM if there are several of them.
- Check whether the device turns on without additional elements, and whether the loading proceeds beyond the splash screen.
- If everything is fine and the device turns on, insert one element at a time to find the problem.
In addition to the drive, the problem may be with the RAM stick or the graphics processor.
Contact the service center
It happens when Lenovo does not turn on (stuck) on the laptop name logo, and the steps discussed above do not help. In this case, the cause of the malfunction may be the motherboard itself. It is impossible to repair it at home, so you will have to contact a service center. Specialists conduct diagnostics, clean the device (if necessary) and give recommendations on further steps.
Now you know why your Lenovo laptop won’t turn on, and what to do if only the splash screen is visible. Start by checking your BIOS settings and making sure your peripherals are connected correctly. Be sure to look at the error that the system throws and try to determine its type. Discarding the peripherals one at a time may help, but be careful not to damage anything. If none of the steps help or you don’t want to disassemble your Lenovo laptop, take it to a service center.
In the comments, tell us if you have had a situation where the laptop does not turn on and only the splash screen appears, and how you managed to resolve the issue.
Hardware faults
Unlike full-size system units, monoblocks are usually sold immediately “assembled”, from one manufacturer. For most models, the buyer receives a guarantee, which will instantly disappear after any manipulation of the case, not to mention the electronic circuits. It is for this reason that repairing this type of device at home is a questionable decision.
You can independently clean the dust that causes the PC to overheat - this procedure does not require complete disassembly of the case. In some situations, the computer does not turn on due to a broken power button - clean the contacts with alcohol.
The most expensive procedure when repairing All-in-One computers is replacing the screen. This module is built into the case, and it is very difficult to buy it separately. If the display is broken, contact the service center and be prepared to pay a considerable amount for repairs.
Diagnostics
Checklist for finding and identifying the problem.
| What's happening | Suspected breakdown | Solution |
| No image on screen | 1. BIOS failure. | Contact service. Flash the BIOS on the programmer. |

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.
Why is this happening?
The fact is that at the initial startup stage, when you have just turned on the laptop and its logo is displayed on the screen, testing of the main components, as well as connected devices, takes place. The BIOS sends a request to devices and receives a response from them. If everything goes well, then the operating system is further turned on and started. In cases where the logo hangs on the screen for a long time (20 seconds or more), this means that there are problems with some of the devices surveyed. The BIOS simply does not receive a response from 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 a 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 one model or another. The new component will 100% work. Accordingly, the computer will turn on. But what if there is no progress even after replacing the wire?
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.
