I have a Dell laptop, just out of warranty, and the touchpad isn't working.  For the most part I use a wireless mouse, but when I want the laptop to be portable, I can't always use the touchpad. I've tried running anti-virus software, thinking that might be the culprit, but everything came back clean.  I don't want to pay for an expensive repair.  Any suggestions as to what might be causing this?  I don't recall any damage to the area.  Thank you.

I'm wondering what are the benefits of having one and would someone recommend me to buy it. I've heard that there is an application that turns speech to text, so it is pretty good for deaf people. Is there anything else Google glasses can offer to someone who is considered healthy and that isn't included/supported in our smartphones?

I have a nexus 4 and I am not quite satisfied with the on-board sound quality. Is there any software that can help me better boost and improve the quality of the sound. Also can anyone provide me with a list of good Bluetooth speakers? Are they worthwhile and do they have any impact on the battery?

Can my mobile be used as Wi-Fi hotspot? I always heard that latest smartphones can be used to share internet connection. What kind of mobile connection is required? Can anyone who tried it, tell me how it is in terms of connection quality? How many devices can be hooked up without losing speed?

Hello! I just bought Samsung S5 Galaxy and loved its functionalities. But there is this problem that it takes a lot of time to charge completely. I cannot afford to put it on charging mode all the time because I have to use it as well. So initially I thought there was some problem with the electric connection and I tried to charge it in less time by using different places to charge, but the result is still the same. It takes hours to charge it completely. Please help me out

What is the raspberry pie? I was browsing the internet and saw that this apparatus was used to automate the air-conditioning systems in the house of individuals. Also I saw that, it could be further used to control the alarm system and act as a universal remote. Is that possible? 

I just got a Samsung S5 and I noticed that the fingerprint sensor is not working properly. When I swipe my finger on it, nothing happens. Is this a software or hardware problem? If it is a hardware problem, is there a need for me to return the device to the retailer?
