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.

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:
 Wrist grounding strap and conductive mat
 Flat screwdriver
 Philips screwdriver
 Polydrive screwdriver
 Plastic tweezers
 Flat plastic pry
 WEEE Annex VII Component
These components are classified as requiring selective treatment.
