My laptop was working correctly until I uninstalled and reinstalled the latest version of Eset Smart Security 4.2.58. Now when my computer tries to go to sleep or hibernate it hangs and the hard disk light continues to flash, but I have to reset the laptop eventually to get out of the hanging state. I have an Acer travelmate laptop with Windows 7 64bit (Home Premium) I have dropbox installed, read somehwere it might be an issue between eset and dropbox. I also tried with the older version and with 0.8.90 What I did was: I uninstalled Eset Smart Security and then ran the eset uninstaller tool and the ndis repairer. After that I installed eset smart security 4.2.58 again. Everything works fine except that when I let my computer go to sleep or hibernate, the hard disk icon continues to flash and the computer does not enter sleep state, it can also not come out of the state and hangs. I have tried uninstalling and reinstalling eset and dropbox, I have tried disabling network sync on dropbox, I have tried disabling eset firewall, nothing works. If I uninstall either eset or dropbox, then the computer enters sleep state correctly and there is no problem.
