Should I get a lenovo G510 or Lenovo Z50-70?

I will not be gaming but heavy internet and spreadsheet use.

They seem similar specs…

I can get £30 off the Z50 so we're looking at £550 v £570.

I think g510 has worse screen and graphics card… But better processor and integrated graphics card (which I'm told is more reliable when not gaming)

Let me know your views please

Do any of you out there recommened Lenovo Laptops?

My dad is planning me to buy a laptop since I graduated. I'm planning to get one of the Lenovo laptops but I'm not sure if they are good. Here is the link to the laptop I would like to buy: http://shop.lenovo.com/...CB0A6C8D1E

I don't play serious games(such as BF3, Bioshock, etc…) but I want a good fast computer. I'll also use it for my school work.

If you recommend different brand/laptop, please tell me!

Why does my laptop make beep noises?

I'm experiencing a beeping noise coming from my computer. If I put in a headset it will stop, but if I tap my headset it will make the beep noise. Same as for the laptop, if it does stop (rare) I give it a little tap to the right of the touch pad it will beep again. I don't know if this is because the microphone is catching the noise or if its an internal hardware problem. Here are my laptop specifications:

Laptop not fast enough to play games? Possible to upgrade? - 1

I have the most recent Lenovo Yoga, and a Pavilion dv6. I bought a couple of games on the Steam sale, but neither of these laptops are good enough to run games like Dragon Age, Far Cry 3, or Witcher 2. Is it possible to upgrade my laptops?
