my Samsung NP-R700 suffered a weird screen flicker yesterday, and since then has failed to boot. Pressing the power switch results in the hard disk light briefly coming on, and then there is just the power light showing a steady blue. The laptop accepts DVDs, and with the samung recovery disc in there, it spins up the DVD every 5/10 minutes or so.
I've tried running with mains power only / battery only / battery and mains combined. I've also tried booting from the recovery DVD with no luck. I'm not very technical so that is really all I can think of trying.
Hope somebody can help.
