This is a troubleshooting guide for the Acer Aspire One model number 725-0845.
- Laptop Will Not Power On
- Keyboard or Keys Not Responding
- Computer Frozen on Start Up
- Malfunctioning Speaker
- Unresponsive TouchPad
Laptop Will Not Power On ¶
The laptop will not power on when pressing the power button.
Dead Battery ¶
If the laptop will not power on when pressing the power button, connect a charger and attempt to power on again. If the problem persists, the charger or battery may be faulty. Consult the Battery Replacement Guide.
Faulty Battery Connection ¶
If the laptop will not power on when pressing the power button, check to ensure the battery is properly inserted on the bottom of the laptop. If the battery is loose, completely remove it using the Battery Replacement Guide and reinsert it. If the laptop still won’t power on, the battery may need to be charged.
Malfunctioning Charger ¶
If the laptop will not power on when pressing the power button, plug the charger into the laptop and check for the orange light on the bottom right of the laptop to illuminate. If the light does not illuminate, the adapter may be faulty, or not receiving electricity and may need to be replaced. If replacing the charger does not resolve the issue, the battery itself may be faulty. Consult the Battery Replacement Guide.
Keyboard or Keys Not Responding ¶
Entire keyboard is unresponsive, or individual keys are missing or malfunctioning.
Unresponsive Keyboard ¶
If the keyboard is not responding, try to restart the laptop. If the problem persists, use an air duster to clear any debris from the keyboard. If the keyboard is still unresponsive, it may need to be replaced. Consult the Keyboard Replacement Guide.
Individual Key Malfunctioning ¶
If an individual key is malfunctioning, there may be debris under the key. Clear the debris out using an air duster. If the problem persists, the individual key may need to be replaced. Consult the Keyboard Replacement Guide to replace an individual key.
Computer Frozen on Start Up ¶
The computer will not boot up, and is incapable of loading up the operating system.
Corrupted Hard Drive ¶
If the operating system appears to run an automated repair process and repeatedly fails, the data on the hard drive may be corrupted. This issue can be fixed by reinstalling the operating system from a factory installation disk. If a rattling or clicking noise inside the laptop is audible, immediately shut the laptop off; the hard drive's mechanical parts are likely failing and the drive should be replaced. Consult the Hard Drive Replacement Guide.
Insufficient Memory ¶
If the computer is running slow on startup, or notifying you of insufficient Virtual Memory, it may need a RAM upgrade. First attempt to disable memory-intensive processes via Task Manager. If the problem persists, consult the RAM Replacement Guide.
Malfunctioning Speaker ¶
The speaker provides no audio or a distorted audio with a static interference.
Improper/Outdated Driver ¶
If there is no audio coming from the speakers, check to make sure the volume is at an appropriate level. If the volume is at an appropriate level and there is still no audio coming from the speakers, the driver may need to be updated. Access the Settings from the desktop, and navigate to the Control Panel. Select Hardware and Sound → Sound. Click on the problem device and select Speaker → Properties → Driver → Update Driver.
Broken Speaker ¶
If the speaker has been physically damaged and/or broken, it can be removed and replaced using the Speaker Replacement Guide.
Unresponsive TouchPad ¶
''The TouchPad is not responding to any input'.'
Misconfigured TouchPad Settings ¶
If there is little to no activity when attempting to use the touchpad, restart the laptop. If the problem persists after restarting, the driver may be outdated. Access the Settings from the desktop, and navigate to the Control Panel. Select Hardware and Sound → Devices and Printers→ Mouse. Under the Hardware tab, check that the device status is "properly working". If not, click Properties → Driver→ Update Driver.
Faulty Touchpad ¶
If touchpad settings are appropriately set and the touchpad is still unresponsive, the touchpad may be defective and may need to be replaced. Consult the Touchpad Replacement Guide.
