    At boot up, Power, Wireless and Bat chg lights turn on for 3 secs then unit shuts down. No onscreen video what so ever!

    I changed RAM modules(2 qty) out and now unit partially boots, Power, Wireless and Bat chg are lit, and stays powered up to the point where the caps lock lights (two of them) blink three times then pauses, blinks 3 times and pauses and so on, but still no onscreen video what so ever!

    HP Blink code says defective memory first, (installed new pair RAM modules 2 x 2gb DDR3) and if that don't solve problem (it didn't) defective motherboard!

    Installed new motherboard, with new DDR3 RAM modules and same condition exists, powers up, Power,Wireless and Bat chg are lit, caps lock lights blink(3 x sequence), and nothing further. No video display what so ever, NO PRODUCT NAME/MODEL, NO BIOS/POST screen nothing. (see attached pic) g71blkcaps.jpg

    Anyone else seen/had this problem?

    thanks in advance
