Too Much Use
If the computer has been running for a extended period of time, it is good to try turning the computer for a short period, in order to let it cool down.
Operating in Warm Environment
If the device is being used in an environment that is very hot and humid, it is possible that the device is unable to cool itself. If you are operating the device in a warm environment and it is overheating or getting very warm, try to move into a cooler place, or consider turning it off for a short period to cool down, and use it in short periods.
The Vents and Fans Are Covered With Dust
Depending on the environment where the laptop is used, as well as how long the user has had the device, dust can build up. If the device does not get proper air intake or outtake, the device will overheat.
Look at the vents on the computer and use either compressed air on the vents or a vacuum to clean off any dust that may be lingering. While the device does not have to be opened, it can be a good idea to clean the fans of the device, by spraying compressed air around the surface of the fan.
Fans Are Covered With Dust
Computers, especially the ultra-slim IdeaPad Flex 15, overheat because of dust stuck in vents or fans. This dust traps hot air in the body of the computer and the air can't leave. To fix this, locate the vent and spray a can of compressed air into the computer. Computers can overheat due to excessive dust and other materials stuck in the vents or fan. To fix this, use a compressed air duster to carefully blow the dust off the vents and fan.
Laptop Will Not Power On

Low Battery or Loose Connection
Make sure that the battery is charged by plugging in the charger from a working outlet and into the device. Also, make sure that the battery is properly attached.
If the charger is plugged into the wall but the light on it is not turning on, then the charger could be faulty. If this occurs, try plugging in to another outlet. If the problem persists, then the charger may be faulty. If this is the case, you may need to purchase a new charger for your device. Note that it must be specific to the device and should come from the manufacturer itself.
If the power supply adapter is plugged into the computer, and the light on the power supply is on, first verify that the adapter is plugged in securely. If the laptop powers on with the power supply adapter plugged in, but immediately powers off after removal of the adapter both after short and long charges, the battery needs to be replaced.
Malfunctioning Power Socket
Verify that the power adapter is plugged in firmly and securely. If it was, check the charging light on the computer itself to see if it is charging. If the power supply light is on but the computer is not charging, then that can mean that the power socket on the computer is broken, and should be replaced.
RAM Won't Post
When the computer starts up, an error is displayed on the screen, stating that the RAM will not post.
RAM Not Aligned
After verifying that the laptop is unplugged, and the battery is removed, take out the screws from the bottom plate of the computer so that the internals of the computer can be accessed. Re-seat the RAM stick back into the RAM socket on the motherboard, and verify that it is aligned correctly.
If after re-seating the RAM and the error message still comes up, try to place the RAM into another RAM slot if available. If after placing the RAM into a different slot and the error message is still displayed, consider replacing the RAM because is faulty.
