Laptop Will Not Power On
You're pressing the power button but it won't turn on.
Dead or Uncharged Battery
Plug in your device with the Lenovo charger and verify that the battery is charging via the indicator light on the front of the device. If it does not charge, the battery or the charger may be faulty. To replace the battery, use this guide
Faulty Battery Charger
Ensure your Lenovo charger is working properly by looking for the charging indicator light on the front of the Lenovo B570. If it is not on, check that the outlet you are using is working properly. Do this by trying to charge an already working device, like a phone. If the outlet is functional, but the laptop is still not powering on , consider replacing the charger.
No Display
You are sure the device is on and running, but the display is not working.
Disabled Display
The display may have been accidentally disabled. To re-enable it, first hold down the Fn key and then press down the F2 key. If the display was accidentally disabled, this should turn it back on.
If this doesn't work, try the previous method again and then hold the Windows key and press P twice. If the device had accidentally been set to Projector mode, this should change it back to Computer mode.
Sticking or Missing Keys
Keys Are Sticking
If the keys are sticking on your device it may mean that the keyboard is dirty. Clean the sides of the key in question with cloth.
Keys Are Missing From the Keyboard
If keys are missing from the keyboard, consider replacing the entire keyboard. If you are unsure as to how, refer to this guide
Overheating
The device is overheating during normal operation and shutting down.
Dust Clogging Fan Vents
If there is a buildup of dust on the fan air vents, it can lead to ventilation problems and cause your device to overheat. To ensure there is proper airflow you should make sure the fan, heat sink, and vents are clean and relatively free of dust.
CPU Overheating
If your CPU is overheating despite proper ventilation and a functioning fan, it may be due to having insufficient thermal paste on your CPU. Thermal paste is a substance that goes between your CPU and the heat sink to allow maximum contact between the two for proper heat dispersion. To solve this, clean off the existing thermal paste and reapply.
Computer Running Slowly
Your device is running very slowly when trying to do basic processes.
Fragmented Hard Drive
If the device is running slowly, it may mean that the information on the hard drive is fragmented. When information is fragmented, it leads to increased read time and therefore slowing your device. To defragment your devices hard drive, search for defrag on your start menu and run the program. If you want to completely change and upgrade your hard Drive, refer to this guide
Outdated Drivers
The only way to fix outdated drivers is to manually locate and update them with newer versions from the manufacturer. The current drivers are found on the product page for the Lenovo B570 on their website.
Too Many Background Processes Running
There may be an overflow of background processes running without your knowing. To minimize these, try downloading Jet Booster, or a similar program that easily allows you to choose which programs you want running and which you don't.
Insufficient RAM
If all other options are exhausted and the device is still running slowly, it may be due to insufficient RAM. Replacing your RAM requires the laptop to be opened.
