This is my first time in the forum, but after no support from Dell over the telephone I thought I would see if I could get help elsewhere.
I bought my XPS15 9530 in February 2015, and have had the same fault occur 3 times, where the laptop will ot power on. Each time I have tried the usual, check the power adapter, disconnect the battery, hold down the button for 'X' seconds etc. with no luck.
The first time occurred in May/June 2015 and was repaired by Dell under Warranty, by replacing the motherboard. The second time occured in November 2015 and again Dell repaired it under warranty by replacing the motherboard. Now in April 2016 the same fault has occured.
Having spoken to Dell the only thing they can do as my laptop is out of warranty is send me a replacement motherboard for a price of £737!! I did complain and said that this was a recorruing fault and there must be a manufacturing issue. They did not confirm this and just said basically no warranty, no help (except for a fee)!!.
I said for £737 I may as well buy another laptop, even though this one cost me around £1500 when I bought it! In hindsight, maybe a warranty extension should have been purchased but I would have hoped Dell would look after customers for re-occuring faults!! I also said my lesson learnt for the day is don't buy Dell!!
