    Recent days i have got an alert 602 to change my internal battery. I tried to locate the CMOS battery by removing the HDD cover then removed the RAM from slots and finally found the battery at a different location. I checked the CMOS with a led bulb it glows. I inserted the battery, RAM and tried restarting it. All I could see is black screen and lights blinking continuously at caps lock and scroll lock. I could hear the CPU fan running. Then tried all the combination for the 2 RAM with the slots. Not even hearing the beep without any RAM. Please help me to resolve it.

    Just now i tried copying the .fd file for F.11 into a flash drive and tried booting it by pressing Win + B also tried with fn + Esc but no use.

    Thanks in advance.

    Laptop details: HP DV5t-1000, Win Vista, Insyde BIOS- F.11, 2X2GB RAM

    I don't think laptops do the beeping, my dell was the same with a badly seated ram stick.....just the capslock flashed no beeping!
