You mentioned that you read suggestions but have you actually tried any of them. To reset the system disconnect the battery and unplug the adapter then press and hold the power button for 30 seconds. Then reconnect everything and try to boot again. Also you could try reseating the RAM. Are you able to run diagnostics (tap F12 immediately at boot) and watch for RAM errors. Try removing one stick of RAM and boot the system and if unsuccessful try the other stick. If you can get into the BIOS try resetting it.
Hello everyone, A BIOS update on my E5590 resulted in the laptop not booting, the screen being blank, as well as the amber light flickering twice, and the white light flickering four times continuously. According to Dell's website, the 2,4 flickering signals a RAM problem. The RAM is original and the computer has been working without a problem. How is this possible? I have read about removing the battery, resetting the BIOS, and so on, but are there any other options? I appreciate your help.
