happens that the laptop he suddenly turns off during use.Why turn off the laptop and what to do?
for disabling the laptop can be hardware and software.It can be turned off when running on battery power and when running on electricity.
If the notebook off occurs during battery operation, the most likely reason for failure of the latter, and should replace him.
The main reasons for self-shutdown the laptop, working from the power supply include: overheating equipment, crack motherboard connector oxidation, bad solder contacts.
In 90% percent of the laptop is switched off due to overheating.Working notebook emits large amounts of heat, especially during the demanding gaming and movies quality.As is known, the cooling system - not the most powerful place in the laptop, in which case there is simply no space for powerful fans.Overheating can occur due to faulty operation of ventilation.Laptop overheating if ventilation holes are clogged with dust or closed while the foreign objects.Ventilation openings are usually closed when working on soft surfaces: a blanket, a pillow, a carpet.
Determine overheat very easily - the laptop is too hot, noisy ventilation more than usual, the constant "snubs" and "squares" in the games, CPU utilization is close to 100%.When this mark is reached, an alarm system to protect against overheating, and the laptop is turned off.Permanent overheating laptop entails the failure of its various parts.Most often peeled from the chip card.
In case of overheating may be required to repair the cooling system: dust removal, replacement of thermal paste, cleaning and lubrication of the fan.If the fan is faulty, then it must be replaced.
Another reason at which the laptop is turned off - crack on the motherboard.This is typical of the old laptops, or in the case of active operation and its relationship unthrifty.Such cracks on the motherboard can occur if the laptop is dropped or hit.Microcracks may not immediately affect the operation of the equipment, but the inevitable result of heating and cooling, they will become wider, and the laptop is turned off.The problem is solved by replacing the motherboard.Replacing the motherboard are expensive, which is not always justified.
laptop is switched off due to oxidation of a connector.This defect appears during the incorrect use of the equipment.For example, use at excessive temperatures or inclusion in a warm room just brought in from the cold of the notebook.To resolve this issue needed to rewire or replace the connector.
And one possible reason the laptop is turned off - poorly soldered contacts.Such a defect is found in cheaper models, and notebooks, which have long and actively exploited.
Switch the notebook off and programmatic reasons.
This may be due to antivirus software, which consume a lot of resources, especially when scanning files or disks, loading the CPU to 100%.We solve the problem of switching off some of the functions and the inclusion of anti-virus scanning on request only.
following software reason - it is malicious and incorrect programs leading to "hang", which loads the CPU at 100%.This triggered overheat protection and the notebook is switched off.It wanted to get rid of viruses and remove incorrectly written programs.
reason for disabling the laptop can be an operating system error, incompatible applications, software errors.
laptop shuts down unexpectedly happens when a fault externally built and connected equipment.
