****** Page 3 ****** Self-Repair This chapter highlights the limited self-repair capabilities of the product. Prior performing self-repair, familiarize yourself with the Safety Guidelines and Recommended Equipment sections first as described in the chapter “Disassembly Procedures”. Depending on model, the following key components are eligible for self-repair (if applicable); • Battery pack HDD /SSD module • DIMM module(s) • WLAN module • LTE module If a particular key component is listed and thus would be eligible for self-repair, but is not described in the ” Disassembly Procedures” section, then this component is either not present on the respective model, or it is present but embedded on the motherboard and therefore not eligible for self-repair. NOTE: Do not attempt to replace other components than those listed above. NOTE: For replacement parts, always use only Acer certified components in order to safeguard quality, optimum system performance, stability and reliability of the product. NOTE: Any damage to the product that occur during self-repair, or which has occurred as a result of a careless or unsuccessful self-repair attempt, is not covered by the standard product warranty. Software Recovery This product has embedded software recovery tools which can be used to either perform a partial or full software recovery, but also to create a Factory Default recovery media. For more information about the software recovery options, how to perform a software recovery or creating a Factory Default recovery media, please refer to the chapter “Recovery” which is available in the User Manual of the product. NOTE: In the event of not being able to create a Factory Default recovery media, it is possible to obtain a copy of the recovery media through Acer Customer Service (acer.com/support) This is not a free of charge service.

****** Page 4 ****** Disassembly Procedures Safety Guidelines This chapter contains step by step procedures on how to remove and de-install components from the computer. Use the following safety guidelines to ensure your personal safety. Each procedure included in this chapter assumes that you are preparing your computer for recycling and disposal. By performing any of these procedures you acknowledge that any remaining warranty applicable to your computer will be voided. Before you start any of the procedures in this chapter, make sure to read the following safety guidelines and the respective instructions within the chapter. CAUTION! • Turn off your computer and disconnect all power sources before opening the computer cover or panels. • To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface at the same time as touching a connector on the back of the computer. • Take off any metal objects on your arms or fingers such as bracelets, rings or watches and make sure your hands are completely dry. Even if your unit is unplugged, there may still be some remaining electric charge. • If a component does not come out easily, do not forcefully remove it. Instead, check that you are removing it correctly and that no wires or other parts are in the way. • When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. Recommended Equipment The following equipment are recommended to do the following maintenance procedures: e e 1-2 Wrist grounding strap and conductive mat Flat screwdriver Philips screwdriver Polydrive screwdriver Plastic tweezers Flat plastic pry Disassembly Procedures
