I've got two Dell laptops - both are Vostro V131. One of them had numerous hardware problems soon after the purchase - the hard drive died and left button of touch pad stopped working. When I've contacted the support, they basically told me, that I've stolen my laptop.
I forgot to mention - I bought my laptop from my company, which is an official Dell distributor. It was absolutely new, no questions about that, in a never opened box.
Well, when the support "tech" guy asked for my company name, I said that this notebook is my own, no company assigned. Nope, - he said - try again.
And I tried - the company that actually sold me the notebook. No luck. In the end, he just said that there is no warranty for a notebook if I can't prove that it's mine. However, there is no way to show them the invoice or something, they simply play the game of "guess which company name I have in my head".
After that, I tried the same with second Dell notebook. I've got it from another shop a few months before. Although I had no problems with it, I just wanted to see if I have the warranty. You guess right - the company is not correct.
If I am able to learn from my mistakes, I will never have Dell again.
P.S. Just got my new laptop. It's Lenovo.
