I have a DV6 pavillion that has been in mothballs for almost 2 years because i thought the monitor or video card had stopped working (blank screen).
Got it out the other day and decided to put it back together and turn it on as i figured perhaps the problem may not be the screen but something else (such as a virus).
You can imagine my surprise when it booted up perfectly...I was then very suspicious that perhaps it may have a virus. Anyway, it was late at night so I turned it off with the idea that the next day I would tackle that problem.
The next day things did not go to plan...system refused to boot, although I could at that time access bios but nothing more (ie no boot from dvd drive)
I decided to remove the hdd and reformat it using a desktop pc and have completed that task then I removed battery, cmos battery, disconnected power too.
However, I am now having problems at the BIOS level...the system keeps saying the hdd self test needs to be completed (even though the drive is working fine in desktop pc.)
My feeling is that perhaps the virus has got into the bios...or at least the bios may be corrupted.
Anyway, I have inserted a dvd into the drive and am attempting to boot from it (i changed the boot order to dvd)I have tried to boot from Windows 8 cd, after what seems like ages a windows 8 logo comes up on the screen then the systems hangs at this logo.
I am able to run the Primary Hard Disk Self Test. Results displayed on screen after about 5 minutes are as follows;
Primary Hard Disk Self Test
Hard Disk 1 Quick (303)
Hard disk 1 Full (305)
Hard Disk SMART Passed
Press <Esc> to continue
When I hit <esc> the following is displayed
"Hard Disk Test" Failed
"Hard Disk Quick" (303)
"Hard Disk Full" (305)
Memory test pass
I'm not understanding why it is failing the hdd test when I can easily access the hdd when it is installed in my desktop pc!
Have I formatted the drive incorrectly in desktop pc? (desktop pc runs Windows 10 x64)
Do I have a virus in the bios?
I am now seeing a windows automatic repair screen when booting from the hirans cd (hirans cd doesn't have windows 8 automatic repair on it and the hdd has no OS on it because I formatted the drive). This has to be a corrupt bios.
Also, I have tried creating a hirans bootable USB...the computer wont boot from it. I will try creating a windows bootable usb and see what happens
I have created a bootable Windows 8.1 USB, set the BIOS to boot from USB key, however the laptop will not boot from it (just keeps coming up with a hanging screen showing same windows logo as before.
Is there a way to flash the bios without having to boot system?
Is there a way to clear the cmos? (ie where are the cmos jumpers on this laptop?)
