Chapter 1. Safety information This chapter presents following safety information that you need to be familiar with before you service a ThinkPad notebook computer.
• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. • Do not work alone under hazardous conditions or near equipment that has hazardous voltages. • Disconnect all power before: – Performing a mechanical inspection – Working near power supplies – Removing or installing main units • Before you start to work on the machine, unplug the power cord.
Consider these conditions and the safety hazards they present: • Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) • Explosive hazards, such as a damaged CRT face or a bulging capacitor • Mechanical hazards, such as loose or missing hardware To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task.
– When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector-outside shells on these systems. – Use the round ground prong of the ac plug on ac-operated computers. Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting. If you select an incorrect drive, data or programs can be overwritten. If the computer is shipped with both an mSATA solid-state drive and a hard disk drive, the mSATA solid-state drive is used for the “cache” function and to support the Intel® Rapid Start Technology.
code. The country code assigned is alphabetic and represents a designated country or region (example: 20AA0009UK). FRU identification Use Lenovo eSupport to identify major FRUs, FRU part numbers, and FRU descriptions for a product at an MT - serial number level. Examples of major FRUs are hard disk drive, system board, liquid crystal display (LCD), and memory module. To identify the major FRUs for a product, do the following: 1.

Go to http://www.lenovo.com/diags. 2. Click Lenovo Bootable Diagnostics. 3. Follow the instructions on the Web site to create a bootable diagnostic medium on a USB device or CD.
Checking the ac power adapter You are here because the computer fails only when the ac power adapter is used. • If the power problem occurs only when the docking station or the port replicator is used, replace the docking station or the port replicator. • If the system status indicator does not blink three times when an ac power source is connected, check the power cord of the ac power adapter for correct continuity and installation.
Checking the coin-cell battery To check the coin-cell battery, do the following: 1. Disconnect the battery connector. See “Disconnect the battery” on page 64. 2. Remove the coin-cell battery. See “1060 Coin-cell battery” on page 68. 3. Measure the voltage of the coin-cell battery. See the following illustration. Wire Voltage (V dc) Red +2.5 to +3.2 Black Ground • If the voltage is correct, replace the system board. • If the voltage is not correct, replace the coin-cell battery.

The text file contains information on how to reinstall that device driver.
Attention: If you refresh your computer, the programs that came with your computer and the programs that you installed from Windows Store will be reinstalled, but all other programs will be removed. 1. Move your pointer to the top-right or bottom-right corner of the screen to display the charms. Click Settings ➙ Change PC settings ➙ Update and recovery ➙ Recovery. 2. In the Refresh your PC without affecting your files section, click Get started. 3.
Creating and using recovery media You can create recovery media as backups for the Windows recovery environment and the Windows recovery image. If you cannot start the computer, you can use recovery media to troubleshoot and fix the problems on your computer. It is recommended that you create recovery media as early as possible. Once you create recovery media, keep them in a safe place and do not use them to store other data.
3. Select a preferred language and then select a preferred keyboard layout. 4. Click Troubleshoot to display the optional recovery solutions. 5. Select a corresponding recovery solution according to your situation. For example, select Reset your PC if you want to reset your computer to the factory default settings.
