Hello, i'm writing here because i've a problem with my Ultrabook envy 4 1200-el.
i bought it 6 months ago.
it's a win 8 64 bit
Intel(R) Core(TM) i5-3337U CPU @ 1.80GHz
Intel(R) HD Graphics 4000
IDT High Definition Audio CODEC
Bios F.21
Well, it was all ok but around 2 weeks ago the suonds and videos ( streaming or downloaded,reproduced with any kind of players ) started skipping or stuttering and making such as a metallic noise. But the most important thing is that all this staffs starts when my sleebook is charging up..ONLY DURING THE GHARGE!!
for example: a movie reproduced when the pc is on battery supply is OK..NO PROBLEMS. The same movie reproduced, when the pc, is charging up shows the problems described before, during all duration of the movie and the charge.
I've tryed to update drivers( audio, graphic, bios, win 8.1 ) but no news; i've changed my charger but it's same story.
Then i've inizialize my pc with the factory settings...deleting all the programms downloaded, all personal file...everything.
In this way IT SEEMS to be BETTER ( now audio sometimes skips but there is no metallic noise )...Now i think that from the date in which i've bought my pc and the date in which the problem has started there is one windows update or hp update , or more than one, that amplifies the problem.
The real problem, for me, is mechanical...in the connection between pc and the pin of charger.
So i' m asking for suggest or a solution ..if it's possible
Thank you for the attention.
