This chapter presents following safety information that you must be familiar with before you service a ThinkPad notebook computer... General safety on page 1 Electrical safety on page 1 Safety inspection guide on page 2 Handling devices that are sensitive to electrostatic discharge on page 3 Grounding requirements on page 4 Safety notices (multilingual translations) on page 4

Page 8

Safety inspection guide The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions... As each machine was designed and built, required safety items were installed to protect users and service technicians from injury... This guide addresses only those items... You should use good judgment to identify potential safety hazards due to attachment of non-ThinkPad features or options not covered by this inspection guide...

Page 9

Handling devices that are sensitive to electrostatic discharge Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD... ) ESD damage can occur when there is a difference in charge between objects... Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge...

Restoring the factory contents by using the product Recovery Disc Set When the main storage device is replaced because of a failure, no product recovery program is on the new drive... In this case, the customer must use the Recovery Disc Set to recover the tablet... Order the Recovery Disc Set and the drive at the same time so that the customer can restore the tablet to the factory default settings by using the Recovery Disc Set after the new drive is installed... For information about which discs to order, go to: http://www... lenovo... com/serviceparts-lookup...

Page 36

You can create recovery media as backups or replacement for the Windows recovery image... With the recovery media, you can troubleshoot and fix the problems on your computer even if you cannot start the Windows 8... 1 operating system...

Page 39

Recovering your operating system if Windows 10 fails to start The Windows recovery environment on your computer is capable of operating independently from the Windows 10 operating system... This enables you to recover or repair the operating system even if the Windows 10 operating system fails to start...

If the LCD you are servicing has two or less visible defective pixels, it should not be considered faulty... However, if the LCD has three or more visible defective pixels, it will be deemed as defective by Lenovo and it should be replaced...
