To troubleshoot some common problems with a Lenovo PC, try and restart the computer, and use an antivirus program to get rid of any viruses that could be causing the problem. Check any recently installed programs and drivers. If the computer does not power on at all and power is available, try and perform a power supply reset. If the computer does not boot properly, use the beep codes to determine the cause of the problem.
One of the most common ways to resolve Lenovo PC problems is to shut down the computer and restart it. If this does not work, the problem could be due to a virus or malware. Use a reliable anti-malware and antivirus program to scan the system.
If the problem persists, check any recently installed programs. Sometimes, Lenovo computer problems are due to a driver crash. If you have the system restore feature, use it to restore your computer to a time when it functioned properly.
If the computer refuses to power at all, check to ensure that there is power and that the power cable is connected to the socket. Also ensure the switch is on. Perform a power supply reset by unplugging the cord, pressing the power button and holding it for 10 seconds. Then, reattach the cord and switch on the computer.
If the Lenovo computer refuses to boot, count the number of beeps and their sequence to diagnose the problem. Remove any installed hardware, including modems, USB drives and printers. Disconnect and reconnect internal components such as memory, adapters and riser cards. This is because these connections may become loose when you move the computer. If the system still refuses to power up or boot, it could mean that the system board, power supply or the processor is defective.
