Re: my keyboard won't work
Assuming that the area below your keyboard is clean, check your keyboard properties and make sure that it is set to the language and country that you prefer (such as English - US). If the area underneath the keys is not clean, use one of those commercial cans of air that are for cleaning electronic equipment. It could also be that the contact(s) for the keys are physically damaged, the cable is bad/damaged/loose, etc. I would check cleanliness and keyboard properties first.

If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.
You have your numbers lock on, press the NumLk key and that should correct it. You will notice on you keyboard that there are small numbers on it below some of the letters, this is so you can use the keyboard has a 10 key number pad/ calculator etc. If pressing the NumLk key does not work, the key may be stuck or you have a bad keyboard
Try attaching an external keyboard to your usb port, if it works you might have an internal keyboard cable loose. Since everything is very cramped up in the notebooks unless you are really confident you may not want to open it up and check the cable yourself. You can send it in for service or warranty repair or take it to a local computer place that you trust and have them check it out.
you will need to reinstall the drivers for the sound card and your sound will work again. You will need to go to the manufactures web site and click on support. than enter your model number and or serial number and then click on search and should bring up a page that has a drop down pages so you can choose drivers and downloads than click on that and find the one that says sound and or multi media. aspire usually uses reltek for the sound driver.
