Question 6

How to change the display resolution on an Xbox with the ACER AL1516W monitor?

Accepted Answer

To change the display resolution of an Xbox on the ACER AL1516W monitor, you must first understand that it is the Xbox console that determines the resolution, not the monitor.

Procedure on the Xbox

Go to Settings > Display and Sound > Video Output
Select the desired resolution
Confirm the changes

Important: Resolutions compatible with the ACER AL1516W

The ACER AL1516W is an older analog monitor (VGA connection) that supports the following resolutions:

640 x 480 at 75 Hz
800 x 600 at 75 Hz
1024 x 768 at 75 Hz

Note: If you select a non-compatible resolution on your Xbox, the monitor will display the message "Out of Range" or will be blank. In this case, change the Xbox resolution to one of the values listed above.

Optimize display after change

Once the resolution is accepted by the monitor, you can:

Press the AUTO button on the monitor for automatic adjustment
Use the OSD (on-screen display) menu to fine-tune CLOCK (frequency) and FOCUS (sharpness) if the image is blurry or poorly centered

Question 8

Why won't my ACER AES023 electric scooter start after charging?

Accepted Answer

If your ACER AES023 does not start despite a full charge, here are the checks to perform in order:

1. Check the battery charge

First, ensure that the 7.8 Ah lithium-ion battery is fully charged. The charger indicator turns green when charging is complete. A low battery displays the error code 0E on the LED display. Allow it to charge for the full 3 hours if the scooter turns off quickly after starting.

2. Press the start button correctly

Starting requires precise action: press and hold the start button for 3 seconds. The LED screen will light up. A short press does not activate the scooter. Make sure to maintain pressure for the entire duration.

3. Check the folding system lock

For safety reasons, the folding platform must be completely locked before the scooter can start. Mechanically check that the folding system is properly closed and clicked into place.

4. Interpret error codes

If the screen displays a code:

0E: low battery - recharge completely
3E: controller overheated - stop riding and let cool down
9E: motor blocked - restart or contact support

5. Complete restart

Hold the handlebars firmly, place one foot on the platform, use the other foot to gain momentum, then gradually press the accelerator after the first few meters. The motor should then start.

If the scooter still does not start after these checks, consult an authorized ACER repair shop.

Question 9

My ACER H9500BD projector is tripping the circuit breaker, how can I resolve this issue?

Accepted Answer

A tripped circuit breaker generally indicates an overload or an electrical fault. The ACER H9500BD consumes a maximum of 445 W. Here are the checks to perform:

Electrical Circuit Overload

Is your wall outlet on a dedicated circuit or shared with other high-power devices (air conditioner, heater, another projector)? Try plugging the projector alone into another outlet to eliminate an overload.

Check the Power Cord

Inspect the power cable (plug side): look for signs of wear, scratches, wet spots, or damaged insulation. A faulty cable can cause a short circuit. If the cable is damaged, it must be replaced.

Clean the Dust Filter

A clogged filter blocks ventilation and forces the projector to overheat. The thermal protection activates and may trigger an abnormal power cut. According to the manual, the filter should be cleaned every 1000 hours. After cleaning, activate the High Altitude mode to optimize ventilation.

Check the Temperature Indicator

Observe the LED (indicator) Temperature of the device: if it blinks rapidly, this indicates a fan failure. A ventilation failure causes overheating and risks a power cut. The fan should be inspected or replaced.

If the Problem Persists

If the circuit breaker trips upon startup or after a few seconds, this suggests a serious internal fault (damaged capacitor, failing insulation inside the device). The projector will require professional repair. We recommend contacting an authorized ACER technician.

Question 10

What does the red battery light flashing mean when the ACER EXTENSA 2511 is disconnected from the power supply?

Accepted Answer

According to the documentation for the ACER EXTENSA 2511, specific details about the indicator light codes are not documented. However, on this laptop model, a flashing red light while the device is disconnected from the power supply generally indicates a charging or battery issue:

Possible causes:

Battery fault: The battery may be damaged or worn out (the manual states that batteries support a minimum of 400 charge cycles). It may not be recognized properly by the system.
Charger issue: The power adapter may be supplying incorrect voltage or may be faulty.
Dirty charging contact: Dust or oxidation may prevent proper contact at the connector.

Actions to take:

Gently clean the charging connector with a dry cloth;
Try another compatible ACER charger if you have access to one;
Completely turn off the computer, wait 30 seconds, then turn it back on;
If the problem persists, contact Acer support with your serial number (referenced in the system settings of the EXTENSA 2511).
