Dell inspiron 15 N5050 screen goes blank

[passete]

I have this wierd problem, sometimes the screen goes blank (picture still ok on hdmi and vga), only way to get the picture back is to close and open the lid.
I'm running bios A03, and it seems that bios A05 cures this problem.
My problem is that i don't have an original 65 Watts Dell Charger to flash the bios.
I need at least 10% of battery and the original charger ... what the hell
Motherboard is :
10316-1
DV15 HR
48.4I916.011

Anyone with a A05 Bios dump or other Tips
Thanks guys

Yeah my friend, this A05 seems correcting the problem, but i guess that ME is wrong and fan is dozed out

Re: Dell inspiron 15 N5050 screen goes blank

does not make sense cos its latest version extracted from web update with clean me

try this, i have taken your me and put A05 ver on top of it

be sure to remove cmos bat

if this does not work try running web update file with /forceit command line
this will ignore any worning like adapter, battery wrong board etc etc

No change, fan is spinning crazy ...
I never done this manipulation with webupdate ..., is this exclusive to Dell ?

Passete, any chance that it just something as simple as a dodgy screen cable, i've come across numerous laptops with similar issues, sometimes screen distortion & flickering but have had one or 2 that does exactly as you mention,I had a Toshiba Satellite C660 in about 3 weeks back, worked fine but intermittently screen would go black just as you described, closing the screen approx 3/4 of the way down and the screen would come back on again. Changing the screen cable sorted the issue, you could also try upgrading Display drivers or maybe even boot into Safe Mode and see if the issue still exists

It seems that the force option, only works with a battery and without the charger :

Lol, No chance, the battery is flat (0% charge) and i get an error when i try to force the update.
I have replaced the bios chip with a brand new winbond, screen is not turning blank for now, let's hope that the problem was related with the original bios chip.
