This problem is almost definitely a hardware issue, however you can try reinstalling the sound card driver found on Gateway's website: http://www.gateway.com/gw/en/US/content/...-downloads. If this doesn't work, you need to consider replacing the speakers or seeing if your laptop is still under the factory warranty.
Hello - first connect your laptop to its AC adapter to ensure a dead battery is not the issue. Also, disconnect any external devices connected to the laptop (i.e. mouse, USB device, etc.). If this doesn't help, disconnect the AC adapter and remove the battery (guide is provided by our page). Leave the battery disconnected for at least a minute, then reconnect and try powering on. If this doesn't work, most likely the hardware of the laptop has failed in some way, and you should either contact Gateway for recommendations, or just take it to a computer repair shop to have them diagnose the issue.
Hello, the more your laptop is used the more the adapter will become hot to the touch, generally speaking. An AC adapter being warm is quite normal - however if it becomes hot enough to harm your hand after touching it, there is a problem. There could be something wrong with either the laptop or the adapter. If you are still able to charge your laptop while the adapter overheats, then the issue is probably with the adapter. However, if there is no charge running through to the laptop, then the issue is most likely in the power connection in the adapter and the laptop. Check the adapter and the adapter cords for any damage, particularly the end of the adapter cord which connects to the laptop. If any damage is found, replace the adapter and/or have the laptop repaired. If the adapter becomes hot very quickly after plugging it in, then you need to have a computer repair shop take a look, because it is a danger to use.
