Hello Sparkles1. Thank you for confirming. I have tried many times, and just did again, to enter the F2-Diagnostics screen on start-up but it won't even get that far in the boot cycle. It almost immediately goes right into the single-blink mode.
The laptop is a dv7-1260us, running an AMD X2 Turion 64 processor. I am consdering buying an upgrade replacement AMD X2 Turion, 2.4 Ghz. There are lots of resources online to weed through to find out which one I should go with. Do you have any suggestions on this?
Thank you.
