Acer PCs have a set of indicator lights that communicate the state of the system, the hard disk drive and other components. While these lights are useful when troubleshooting devices or determining whether the computer is awake, asleep or off, the blinking of the light-emitting diodes can be distracting if you leave the PC on while you sleep.
Things You'll Need
- Phillips screwdriver
- Antistatic wrist strap
Turn off the Acer and disconnect the power cord after the power light on the front of the computer turns off.
Press the power button to dissipate all electrical charge from the motherboard. Unplug all cables and peripheral hardware from the computer.
Remove the thumbscrews or crosshead screws that secure the cover panel to the computer case. Push the panel toward the back of the Acer PC.
Pull the panel off the case. Put on an antistatic wrist strap or touch the chassis to prevent damaging the internal hardware with electrostatic discharge.
Find the tabs, located near the top, bottom and middle of the chassis, securing the front cover to the case. Release the tabs; then pull the front cover off the case. Disconnect the LED cable connected to the opposite side of the front cover.
Locate the LED cable connected to the socket near the side of the motherboard closest to the front of the case. The LED cable is made up of several colored wires.
Disconnect the cable from its socket to stop the LED lights from blinking. If the cable is separated into different segments, check the labels on the wires to see which wire is assigned to the LEDs; then unplug that wire. Reassemble the PC.
Tips & Warnings
- On some models, disconnecting the LED cable also disables the power and reset switches.
- Disassembly steps vary from model to model. For example, some Acer PCs lack a removable front cover.
- Contact Acer before disassembling the PC, as opening the case may void your warranty.
- Removing the LEDs from Acer notebooks and netbooks is not recommended, as it requires the complete disassembly of the computer or the removal of a central component, such as the switch cover.
