In most cases it is an expensive component and replacement will not be cheap.
Recommendations for Maintaining the Vitality of a Lenovo Notebook
Careful and tidy attitude towards technology significantly prolongs the term of operation, declared by the manufacturer.
Avoid mechanical influences on the laptop: intensive or violent shaking, dropping or bumping lead to the failure of the internal components of the device.
Avoid contact with liquids or high humidity in the air. Oxidized contacts can lead to short circuits and costly repairs.
Carry out regular mechanical, thermal paste and system cleaning. In this way you prevent the device from overheating and the operating system from working incorrectly.
It keeps rebooting or shuts down
The notebook may restart infinitely before Windows boots. It is a serious hardware problem, maybe the South Bridge is overheated, usually because of a short circuit in it. Most often it happens because of USB breakdown (remember what you put in the USB connectors).
Or processor overheating due to clogged cooler or loose fit of radiator. But it happens seldom and is usually accompanied by high fan speeds. Your notebook may shut down or restart at different moments.
In the absence or poor power supply the following picture can be observed: the device turns on, but quickly fades because of the dead battery.
How to reset the hardware
To perform a hardware reset, follow these steps.
- Disconnect your notebook from the mains or other power supply. This includes disconnecting the notebook from the charger, as well as removing the battery.
- Press and hold the power button for approx. 20 seconds
Why do this? It is very simple. The notebook stores the remaining charge in the capacitors to keep the settings. When you turn on the laptop without power supply. this charge disappears and all the settings are lost.
If this does not work go to the next step.
Turns on, displays a splash screen or writes something and hangs
It is possible that the start screen saver appears or information about the laptop is displayed, but then nothing happens, also something beeps or writes about errors. The likely cause is a problem with the BIOS settings. on the laptop I described in my article. You just need to enter BIOS and reset to defaults.
In different versions this item may be in different places, but it is called roughly the same “Load BIOS Defaults”. the key word is “defaults”. Then exit with “Save Settings and Exit”.
Please note that the system may report a problem but you can continue booting if you press the button. For example, it can write “Press F1 to continue” which means you press F1 to continue booting. Usually happens when the battery on the motherboard is dead (not to be confused with the large battery), disrupted time and bios settings. The battery has to be replaced in the service center.
This is the easiest thing you can do yourself.к. The problem may be more serious, for example a hard drive or RAM failure.
with a certain skill problems with the hard drive blindly can be diagnosed by listening to your laptop When you turn on the working drive spins the engine and crackles for a couple of seconds, reading the information. If there are problems, the motor may try unsuccessfully to start several times, or the heads cyclically crackle while trying to read something from the plates, while everything hangs on the screen.
