This section provides introduction to a set of diagnostics and troubleshooting tools at Lenovo Support Web site, the Vantage app, and in your computer. They can help you diagnose common software and hardware issues.

The following table lists these diagnostics tools and the recommended conditions for each tool.

Diagnostics tool Recommended scenario
Troubleshoot and diagnose at Lenovo Support Web site You want to have an online troubleshooting or scan of hardware and drivers on your computer.
Hardware scan
  • Your computer is installed with the Vantage app.
  • You want to perform basic examinations of the hardware components.
UEFI Diagnostics tool
  • You cannot log in to the operating system.
  • Your computer cannot connect to the network.

If you see a message that is not included in the following table, record the error message first, then shut down the computer and call Lenovo for help. See “Lenovo Customer Support Center”.

Message Solution
0190: Critical low-battery error The computer turned off because the battery power is low. Connect the ac power adapter to the computer and charge the batteries.
0191: System Security - Invalid remote change requested The system configuration change has failed. Confirm the operation and try again.
0199: System Security - Security password retry count exceeded. This message is displayed when you enter a wrong supervisor password more than three times. Confirm the supervisor password and try again.
0271: Check Date and Time settings. The date or the time is not set in the computer. Enter the UEFI BIOS menu and set the date and time.
210x/211x: Detection/Read error on HDDx/SSDx The storage drive is not working. Reinstall the storage drive. If the problem still exists, replace the storage drive.
Error: The non-volatile system UEFI variable storage is nearly full.

This error indicates that the operating system or programs cannot create, modify, or delete data in the non-volatile system UEFI variable storage due to insufficient storage space after POST.

The non-volatile system UEFI variable storage is used by the UEFI BIOS and by the operating system or programs. This error occurs when the operating system or programs store large amounts of data in the variable storage. All data needed for POST, such as UEFI BIOS setup settings, chipset, or platform configuration data, are stored in a separate UEFI variable storage.
Press F1 after the error message is displayed to enter the UEFI BIOS menu. A dialog asks for confirmation to clean up the storage. If you select “Yes”, all data that were created by the operating system or programs will be deleted except global variables defined by the Unified Extensible Firmware Interface Specification. If you select “No”, all data will be kept, but the operating system or programs will not be able to create, modify, or delete data in the storage.

If this error happens at a service center, Lenovo authorized service personnel will clean up the non-volatile system UEFI variable storage using the preceding solution.

The battery-charge LED indicator (hereafter referred to as LED indicator) blinks to help you diagnose and solve some computer problems.

Indicator blinking patterns

The LED indicator blinks amber first and then white continually, consisting of different blinking patterns. Each blinking pattern corresponds to an error code. For example, when the LED indicator blinks amber once The illustration of indicating amber LED indicator and then blinks white twice The illustration of indicating white LED indicator , the blinking pattern The illustration of indicating amber LED indicator The illustration of indicating white LED indicator corresponds to error code 0001.

Refer to the blinking patterns and error codes in the table below to solve your computer problems.

  • The LED indicator blinks automatically only when the error in the following table occurs.
  • The LED indicator blinks continually until the computer turns off. If you need to interrupt the process, press power button for a few seconds.
  • Do not attempt to service a computer yourself unless instructed to do so by the Customer Support Center or product documentation. Only use a Lenovo-authorized service provider to repair your computer.
