speckytecky Posted June 17, 2013 Posted June 17, 2013 We have a few Lenovo M92Z all in one 23" computers running Windows7 (64bit) - occasionally the odd one will hang during shut down. Resulting in a black screen with the power on button still illuminated. Keyboard and mouse closed down and the only way we have found to get them back to life again is to do a hard reboot. Any thoughts please on what would be the cause of this?
speckytecky Posted June 18, 2013 Author Posted June 18, 2013 Posted the OP a bit late to catch anyone's thoughts perhaps - any suggestions would be very welcome? I'm thinking BIOS perhaps?
mac_shinobi Posted June 18, 2013 Posted June 18, 2013 (edited) Download & install system updater run and install any updates specifically bios, graphics, etc See if its still the same. Only other thing but doubt its related is on our laptops a similar thing happens is the ram that is used for onboard graphics gets corrupted ( physical ram modules are ok ) but then you dont see anything on the screens ie laptop or external via vga and we have to disconnect cmos battery for aprox 10 seconds , re connect it and you get the display back ( as it clears the area of ram that deals with the onboard video ) Not sure if or how that will help with the desktops seeing as you get the issue when attempting to shutdown etc Edited June 18, 2013 by mac_shinobi 1

mac_shinobi Posted June 18, 2013 Posted June 18, 2013 no problem - anything to help a fellow edugeeker out when I can
mac_shinobi Posted June 18, 2013 Posted June 18, 2013 Thanks as ever @mac_shinobi. Some useful suggestions. If that fails may need to book a warranty call
speckytecky Posted June 18, 2013 Author Posted June 18, 2013 Sadly I suspect I know what their response will be - reimage! If that fails may need to book a warranty call
mac_shinobi Posted June 18, 2013 Posted June 18, 2013 Sadly I suspect I know what their response will be - reimage! Getting anywhere with the shut down problem
speckytecky Posted June 19, 2013 Author Posted June 19, 2013 Not yet - haven't had a chance yet as I'm only part time! Getting anywhere with the shut down problem
