I have a 1720 that enters sleep mode/hibernates repeatedly whilst actively working.
The screen goes off and after 30seconds the system shuts down with the blue power light pulsing slowly - 1 press of the power button and the system will come up again with the sign in screen, after signing in the system returns you to the place you were before it shut down.
This can happen continually or sporadically
I have updated the BIOS to A09 and installed the Video driver download - set the power management to never sleep but still it happens.
There are a few people experiencing this but there does not seem to be any posted solutions. Has anybody had any luck fixing this problem please?
Any help would be appreciated.
