Computer Does Not Power On
The laptop does not respond when pressing the power button.
Malfunctioning Battery
Ensure that the power adapter is plugged in and the light next to the charging inlet is lit up. If this light is not lit, then the power adapter may require replacement. If the light is on and the device is not charging, the battery needs replacement.
No Boot When Powered On
The laptop turns on to a blank screen and does not proceed to the operating system.
Blank Screen
Once the laptop is powered on and you are at a blank screen, press the ESC and then press F2 to follow the prompt. Select “System Tests” to proceed and then your laptop will perform a quick hardware check to ensure all hardware components are operating normally. Depending on the diagnosis, please proceed to that heading in this troubleshoot guide.
Failed Hard Drive
If the computer is unable to run windows or often crashes, refer to the Blank Screen section above. The test will diagnose any hardware components that are not functioning properly. If the hard drive is stated, it needs replacing otherwise the processor is faulty.
Defective RAM
To determine if your RAM is faulty, open the control panel, go to System and Security, then administrative tools, and run the application Windows Memory Diagnostic. If the laptop is not booting up, refer to the blank screen section to run a hardware diagnostics test to see if the RAM is faulty.
Failed Motherboard
It is important to eliminate all other hardware components that could be related to a motherboard in order to determine that the motherboard has failed. If you have gone through all relating components such as failed hard drive, RAM, CPU, battery, and cooling fan then your motherboard could have failed. Non-physical motherboard related issues could be blank screens or continuous crashes. Physical motherboard related issues could be burning marks or a burning smell and damaged components on the physical board itself. If any of these non-physical and physical symptoms are present AFTER checking all other hardware components, then the motherboard could be faulty and should be replaced to prevent further damage to other components.
Display Errors
The screen does not respond to power or respond to physical touch.
Improper Display
The display is not functioning properly. Check to see if an external display via an HDMI cable is functioning. If it displays on the external device then consider replacing the LED’s lighting up your screen. If it does not display on the external device then consider replacing the processor.
Overheating
The laptop gets very hot during usage and the fan is either non-responsive or very loud.
Dust in Vents
Open the computer and gently but thoroughly clean the dust off of the fans, use a dry cloth or a can of compressed air to assist you.
Defective Cooling Fan
If the option above does not solve the overheating, listen for the cooling fan that should turn on during laptop usage. If you cannot hear the fan, consider replacing the cooling fan.
Wireless Connectivity Issues
The laptop is experiencing connectivity issues when connecting to wireless networks or Bluetooth devices.
WiFi Connection Issues
If you are experiencing issues trying to connect to a wireless network through WiFi , try reinstalling the wireless network adapter driver. If the problem still continues, consider replacing the wireless network card component inside the laptop as it has become defective.
Bluetooth Connection Issues
If you are experiencing issues with Bluetooth connectivity, try removing any wireless interference that may be blocking the Bluetooth signal. If the problem continues, check if there is any Bluetooth driver update on your device and update it. If you are still having connectivity issues, try to pair the Bluetooth device by removing and pairing it again.
