Hi, I have a samsung series 5 notebook laptop, last night (while running from the battery only) the battery came out and the machine turned off. When I try to power it on, there is no spinning of the hard drive, the machine displays all LED's and the samsung logo on the screen, and has a series of fast beeps( about 15 beeps in a row) I can get on to the BIOS, but nothing is detected in the boot list. I took it to currys, they ran a diagnostic test via USB pen, which found that the CPU, RAM, motherboard and screen were fine. What could be the problem?
Thanks
