Buddy of mine works at a laptop repair, states the following:
Never buy an HP (I found it the hard way); after Carly Fiorina gutted the company, they have among the worst quality control. Think Compaq (which merged with HP). That's what they've become. Several thousand HP laptops have a known design fault in which the integrated graphics card burns out and forces the ($500) replacement of the entire motherboard. Conveniently for HP, this seems to happen at around 16 to 24 months after purpose, or conveniently after the warranty expires. By all ethical and good business standards, this should have been a recall. There is a likely class action suit in the works, which I signed up for---- always nice to make the trial lawyers rich. But if it costs HP a few million or so, more power to them. Meanwhile, that's $500 I'll never see again.
Anyway, my friend says they repair very few Sony or Lenovo laptops; and usually when they do, it's because the owner put an eggo waffle in the DVD drive or something. Don't remember hearing anything one way or the other about Toshiba, but that's probably a good sign for that make.
Asus also makes good notebooks I hear, but I don't have any verification.
And yes, I wish I'd talked to my buddy before buying that HP ($1500) laptop instead of relying on on-line reviews!
Best of luck on whatever you buy!
