I have a lenovo Yoga and the mouse/trackpad drives me nuts?

Only a tiny portion of the mouse right clicks, the rest is left, and it is always dragging/scrolling. Is there a way to make it work like a regular laptop mouse? I just want it 50% left click, 50% right click and I want it to move the mouse. I do not want it to do anything else. Is there a way to do this?

Can I upgrade memory and graphics card in my laptop?

I have a Lenovo z500t touchscreen laptop (core i5, 4gb RAM, 1tb hard drive, Intel HD4000) but it runs pretty slow with some games, even on low resolution. I know I have a free slot for RAM but does it have to be the exact same size and model RAM that's in the other slot or can I (for example) get an 8gb ram to work alongside my 4gb? Also I would like to upgrade my graphics card but I understand some laptops come with them integrated and therefore can't be changed I'm not sure if mine is able to or not.

No input detected on LG TV when connected to my Helix via mini-DP to HDMI adapter?

Today I tried connecting my Lenovo Thinkpad Helix to my LG 24MN43D TV using a mini-DP adapter and a separate HDMI cable, however I'm getting nothing - no input detected whatsoever on the television. Both the adapter and the cable are new.

Does anyone know what may be causing this and how I could fix this? Any help is appreciated.

Good laptop for university student?

I'm in grade 12 at the moment, but am feeling the need to get a laptop very soon. I'll be using this laptop for when I go to university in september, so it has to be a decent/good one. I don't want to get a Mac, since I don't have 1000+ dollars to spend on a computer and my family already owns an iMac. I'm starting to think that I would like one with a touch screen, and can flip into a tablet, but I'm still not 100% sure… I know those are becoming more and more popular. My brother uses an iPad for his power points for uni, and a laptop for his work, so I'm thinking maybe to get one object with both those in it. I'm not overly great with knowing what computers are best, so any help is appreciated. I'd also like to keep it around the 500$ range.

Which of these laptops should I buy?

Hi

I want to buy a laptop, but I'm not certain which one of these models I should buy.
1. Sony VAIO Fit 15E SVF153290X - Touch
2. Sony VAIO Fit 15E SVF15328CX
3. ASUS N550JK With Leap Motion
4. Lenovo Flex 2 - A

My main uses for the laptop are mixing and composing music (using Cubase 5), doing basic designing in Photoshop, and occasionally playing video-games.

I've read about all the technical details, and I'm more interested in the actual experience of using these laptops

So, I would highly appreciate answers based on personal experience. No matter which of the mentioned laptops you've had experience using, I'd be more than happy to hear about it.

I will choose the best answer personally.

Should I buy the MacBook Air?

I already have a Lenovo Y510P which I use for gaming, but I was wondering if i should buy an apple laptop for college. The reason I'm contemplating the purchase of an apple laptop is because I have been told it is very efficient and is very hard to get a virus on.
