I have an Hp Envy Dv7-7205tx laptop notebook. Specs are Intel Core i7-3630Qm, Ram 8gb single stick, 120Gb ssd by micron and an 32gb msata. The problem is i got an update by hp support assistant for bios as my bios was Insyde F.12, 3/09/2012 and the update i got was BIOS Version:F.2D Rev. A
Released:26 Aug 2014 So i installed and proceeded with the update. it all went fine and after completion the laptop booted up.
After reboot the laptop doesnt boot up. No beeps, No post, Nothing on the screen just black. No led light indication/blinking. The Led remains turned on not blinks. The fan spins correctly but to no avail it wont boot or show up anything. After the update i waited for 15-20 mints thinking it would boot up but it did not do so.
I have possibly tried all solutions given on the internet but to avail nothing works.
thesolutions i tried.
1. Removing battery Drained all the residual charge by pressing power button power plug disconnected (Not working)
2. Tried removing Rtc battery to reset CMOS (not working)
3. Reseating and changing the ram in the other slot(Not working)
4. Hp Bios recovery method using usb stick (does not bootto or go to usb I dont know why. Hence not working)
5. Hp Recovery through key combination of Windows key plus B and also with V key. (No change or response whataoever)
I need desperate help.
