I have a Dell Inspiron 1764. The BIOS version was A05. There were a few options that were grayed out so I could not use them example load defaults. I also tried do this by pressing the designated F9 key but all I got was a beep. I downloaded the newest BIOS A13 from Dell. I right clicked on it and Winphlash started erasing the blocks then started to do the flash. It came up with an error message and the flash turned off. I then did the wrong thing and shutdown. A while later I decided to try again but I get no response at all when I press the power button. I removed both the laptop battery and the CMOS battery. An hour later I put the CMOS battery back and tried to power up and again got no response. I also noticed the power light was not lit at all. Do I need a new motherboard? Thanks.
