I have a HP Pavillion DV6-2010sv with a strart up problem (screen is black - cannot boot).
Caps Lock and Num Lock are flashing twice and Wifi is orange.
HP says that the BIOS is corrupted.
I have tried the following without any success :
1) The solution from the article with id 28161121 which says to remove the real time clock battery for 5 minutes.
2) Update bios with a USB drive (FAT32) and pressing Window + B with file 3635F12.fd renaming to 3635.fd, 3635.bin, 3635.rom and 3635.
3) Remove power cable, remove battery, press power button for 1 minute, etc.
4) Dissasemble laptop and clean CPU fan and put new thermal paste.
CPU fan is working ok.
Note: In this laptop i have changed the MB before 1 year.
I do not know what else to do. Any help would be very important !
