Yes, but that was the cause of me not able to get back in as of my OP. It was after i had set the csm to auto.
I had another problem for the rest of the dAY..I LOST MY WIfI...SO I COULDNT answer the latest post. I had to replace modem and now just got online with my acer notebook, with wired connection. Before the wifi problem, i changed the battery.. I have no idea abutThen simply clear cmos. How to properly clear cmos;
1 System OFF and pw cord removed from the pw supply
2 Press the ON button 2~3 times. This removes any residual charge from the pw supply
3 Open the side cover and clear cmos with the clear pins. Modern motherboards use just two pins that you short for at least 10 seconds. Old stuff uses three pins and a jumper that you move for at least 10 seconds
4 Replace side cover and pw cord. Attempt to pw ON and enter the bios. If you still cannot enter the bios, try another keyboard. Still does not work, then the motherboard has probably failed or you have some other hardware failure
2 pins. I did get finally into Bios, and tried to set up default and then i lost wiFi. have to tackle that the next day. TY
