Studio 1537 straight out of the box has major issues re. sleep mode

It seems this is not a new complaint looking at the google results - so why on earth has Dell not done something about it?

My Studio 1537 was delivered Friday.  I have not installed anything or changed the factory defaults & it will not resume from sleep mode.  Whether put in sleep mode from closing the lid or via the Start menu, it's the same story - the keyboard lights up (although the media lights flash they do not stay on) but there's no display & it's totally non-responsive.  I have to shut down via the power button & then get an error message when I restart saying it didn't close down properly, blah, blah.

It's successfully come out of sleep *once* - but that was it.

Naturally, phoning tech support was totally hopeless.  Firstly I was told to reset the factory defaults - even though I'd just finished telling the guy it's fresh out of the box!  Then I was told to download any windows updates while I was on the phone.  When I pointed out that I hadn't connected to the internet yet & didn't have a wireless router as yet (or a cordless phone, so I couldn't go to my laptop) I was told I was "uncooperative" & that the tech guy couldn't help me further!  Oh, & that was after sitting in a queue for 40 minutes & was my third call as no one phoned me back as promised.  Effing hopeless.

The tech guy didn't mention the bios, but a friend of mine suggested I install A05 (I have A04).  Yet another friend warned me it may jeopardise my warantee if something goes awry - & I'm hesitant to change anything since I may need to resort to a refund claim.

I am so disappointed & totally appalled that this common issue hasn't been resolved & that Dell continues to churn out faulty merchandise.  I've just spent $2,500with this company & the fact that I can't even get some USEFUL phone support is SO irritating.

Does anyone else have this problem & has installing A05 resolved the issue?  I've got a good mind to lodge a complaint with the Trade Practices Commissions that Dell is selling goods that are not of merchantable quality & get a refund, but if I can fix it by updating the bios, I'll just put it down to experience & make sure to tell all my friends NEVER to buy a Dell.
