I have been using my R.A.T 7 Mouse for a couple of months, but recently it has started behaving weirdly. Sometimes when I use it, the cursor randomly stops. All the clicks and the buttons function as they should, but the cursor seems stuck. I tried to change the power settings in the control panel, and it worked for maybe a week, and now I am back to square one. What could be the problem?

I have heard many wonderful things about the Raspberry Pi, and I was wondering if it could be used in an office setting. We have a very old (very, very old) computer that we use only to write up invoices with Excel and a very short letter with Word. Could we replace it with a Raspberry Pi? Will it be able to perform these tasks consistently?

Hello. Today I noticed that my fan speed was working at a much slower speed than normal. At first I could not hear it as loudly as usual, and then I checked the temperature readings, and the fan was actually running at half speed, and my CPU temperature was rising. I tried to change the fan speed in the BIOS, but it looked like I wasn’t allowed. I don’t understand why this is so, when I usually take the same steps and BIOS allows me to change with no hitch. Could there be a deeper problem than a faulty fan?

My Acer Iconia A1 tablet has gone mute. All of the sudden, with no warnings or weird scratching sounds, the volume was no more. I tried everything I could think of in the settings, but nothing helped. The headphones still work, and when I connected it to my car radio it plays through the AUX cable with no issue. What I would like to know is 1) if there is a way to know if this is a software or hardware problem and 2) if the speakers can be replaced in case it’s their fault.

Hello. I have been having some problems with my Asus Fonepad 7 since the last update. When I connect a set of headphones to the device, they don’t work. I checked, and the Fonepad tells me they are connected, but no sound comes out of them. I tried this with many headphones, even with another pair from Asus, but nothing. What could the issue be?

I am having problems with my monitor (Acer S240HLBID), attached to an HP Pavilion with Windows 7. Yesterday I tweaked with the settings a bit (mainly changed the resolution and luminosity), and the screen went black with an error message stating “input not supported” appearing almost immediately. I turned the computer off using another monitor, and then tried to use my Acer monitor. It won’t work and the error message appeared again. What could the problem be?

My Nexus 7 is behaving weirdly since the last update. Sometimes it behaves as if I pressed something, even though my hands were nowhere near that point. For example, when I am reading a message, the Nexus types a couple of letters, even though my hands were not on the keyboard. I don’t know if this is related, but it also seems to be lagging a bit more than usual. Are there some settings or some steps I can take?

Hello. My Compaq desktop computer (DC510SFF) does moderately fine for a daily home use, but I would like to try and speed it up a bit. It has a 2 GB RAM, a Pentium 4 3.0 GHz. I just would like to gain some more speed without spending too much money. What should I buy, that is compatible with what I already have?

I bought a Moto X smartphone to use together with my Moto 360. When I try to connect the two, however, I cannot get past the “Choose a device” screen in Android Wear. What could be the issue? The Moto 360 has never been connected to another phone, and the Moto X is brand new.

I have noticed that my Samsung Galaxy Tab Pro will not complete recharging the battery if I don´t reboot it and plug it in again. When I leave it all night to recharge, I wake up and the battery is somewhere around 70%. If I unplug it and then plug it in again the battery will not keep on charging. If I reboot the device, and then plug it in, it will charge to 100%. What is happening, and why?
