Acer N50-650 Manual

Self-Repair

This chapter highlights the limited self-repair capabilities of the product.
Prior to performing self-repair, familiarize yourself with the Safety Guidelines and Recommended Equipment sections first as described in the chapter "Disassembly Procedure".
Depending on model, the following key components are eligible for self-repair (if applicable);

• PSU module
• HDD / SSD module
• DIMM module(s)
• WLAN module
• ODD module

If a particular key component is listed and thus would be eligible for self-repair, but is not described in the "Disassembly Procedure" 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 Procedure
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.

• 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.

Troubleshooting

This chapter provides troubleshooting information for the N50-650 Service Guide

• Power-On Self-Test (POST)
• POST Error Messages List

Power-On Self-Test (POST)
Each time you turn on the system, the Power-on Self Test (POST) is initiated. Several items are tested during POST, but for the most part transparent to the user.
The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the system components, and controls the operation of the power-on password option. If POST discovers errors in system operations at power-on, it displays error messages on screen, generates a check point code at port 80h or even halts the system if the error is fatal.
The main components on the main board that must be diagnosed and/or initialized by POST to ensure system functionality are as follows:

• Microprocessor with built-in numeric co-processor and cache memory subsystem
• Direct Memory Access (DMA) controller
• Interrupt system
• Three programmable timers
• ROM subsystem
• RAM subsystem
• CMOS RAM subsystem and real time clock/calendar with battery backup
• Onboard parallel interface controller
• Embedded hard disk interface and one diskette drive interface
• Keyboard and auxiliary device controllers
• I/O ports
• One parallel port
• One PS/2-compatible mouse port
• One PS/2-compatible keyboard port

POST Error Messages List
If you cannot run the diagnostics program tests but did receive a POST error message, use "POST Error
Messages List "to diagnose system problems. If you did not receive any error message, look for a description of your error symptoms in "Error Symptoms List".
If you are unable to correct the problem by using the "BIOS Messages List" table and "Error Symptoms List" table, go to "Undetermined Problems".
To diagnose a problem, first find the BIOS error messages in the left column. If directed to a check procedure, replace the FRU indicated in the check procedure. If no check procedure is indicated, the first Action/FRU listed in right column is the most likely cause.
