Thanks TommyCooper, I shall certainly get out the vacuum cleaner tomorrow! As I am working in Germany, we'll have to get in touch with a local supplier if the problem persists. Best wishes, Liz

Thanks...really appreciate the comments. We are in the throes of a week's inspection...so have decided to manage without it today..Will have a look at the software later. LC

Yes, thanks. I am a teacher......can't work without it . Will check firmware.

Yes, I've tried a hard reset ....no joy. I switched the SM on without being connected to the computer....it still went out after ca 5 mins, so the prob isn't with the computer or software. Haven't checked connections yet...I know our technician doesn't want anythng oepned up as it would nullify the guarantee, but I will suggest it tomorrow. Thanks for all your help. liz

Thanks, I had wondered about cleaning the filters, but have been told that the 600i range doesn't require filter cleaning! Is that right or wrong? Liz

I have used my smartboard daily for the past 18 months, but recently it has started to switch off for no apparent reason after about 10 minutes. The green onn/off switch stays green, but the lamp goes out. I have to disconnect from mains to get it to restart, then it only works for about 5 minutes. All very frustrating. What do yo think the problem is? Thanks, Liz
