i have changed the intel nortgbridge with integrated vga in it, and after put this new bga, pc boot telling me some cmos error found ( i forgot to connect the 3v battery for testing).

i thought it was a cmos battery message error, so today i put almost all together and when i go for boot, it give me this message and then no more display come.

Have you tried to start it without CMOS battery again?

Does the cursor LED and Caps lock LED blinks continuously?

HP notebooks key to blinks on startup
HP says 1 blink = CPU problem, 2 blinks = BIOS, 3= Memory issue, 4 = Graphics, 5 blinks and it means your system board is dead, 6 blinks = BIOS problem

i didnt try without cmos battery, and it blink continuously (generally continuous blinking is nb failure, but after change 4 bga... and at first boot i got video on the first 2 bga rework. the other 2 bga rework i give notebook to a friend to give it a try with his bga rework station.)
