I'm trying to perform a 'hard' reset and took off the back cover of my laptop. Can someone look at the attached picture and tell me if that is the CMOS battery where indicated with the arrow. To 'disconnect' the battery in order to clear settings, can I just pull out the connector wire? If so, I'm having trouble doing that. I used some force with small pliers but don't want to tug out the entire housing. Is there a trick to releasing the wire from the connector, i.e. disconnect the battery wires?

    Hi grayg, yes, that is the CMOS (RTC) battery module, the white plug is tiny (2-wire) with a handle on each side and you may need tweezers and a small screwdriver to wiggle it out by the 2 handles, don't use pliers as that will squash the plastic plug. Alternatively cut a small slit in the black plastic wrapping with a box cutter to remove the battery and replace it, then close the slit with black electrical tape.

    OK< thank you Purzaw! I will proceed with care. I tried wiggling it out with a couple of small screwdrivers but it's really stuck in there. I thought there might be some sort of release tab, but I don't see one.

    The electrical tape slit might be the way to go.

    As I described in a duplicate thread I posted a few days ago, my problem is that I can get to the windows screen where it asks for my password, but as soon as I put it in, the screen goes black. I can ctr-alt-del to task mgr, but everything I've tried so far is not working.

    It's out of warrantee and I couldn't find anything on Acer's website with a detailed layout of the mother board components for this model, like a service manual.

    It began with my plugging in an older USB external drive and when I 'safely' removed it, the problem started. I was able to view device mgr at one point and removed my graphics driver and it didn't help. I think it's something to do with explorer.exe being corrupt. There seem to similar unresolved issues when I go through the posts here.

    Just a follow up, the battery wire did indeed 'pull' out, but it took some prying with some tips of small screwdrivers to coax it out. I could not pull it out with my fingernails.

    After a 'hard reset', it still did not fix the problem. I had to do a fresh reinstall of windows and load all my programs back in which I'm still in the process of doing.

    I thought I had a backup with macrium reflect at some point, but I could only find a recovery usb I had made.

    I found diskgenius mentioned and figured that out by discovering you use it effectively you need to first create a bootable diskgenius PE within the program onto a USB drive. Then fiddle with the BIOS (press F2 repeatably upon startup to get there), enable F12 in the BIOS. Reboot and press F12 repeatably to get the options to boot from USB, to your usbPE drive you created.

    I had already followed these directions to create a 'copy all files' clone onto a 2TB USB drive, but when I went to test reinstalling the clone from the USB drive to the Acer laptop, the program wanted an system image file, which I did not create and don't remember a prompt to create. So I created the separate USB stick bootable diskgenius PE. Booted from that, and could see both my original Acer drive and the backup I made onto the USB 2TB drive.

    From there I did a system migration from the USB 2TB drive back to the Acer. Shut down, unplugged the USBs and it booted back OK.

    Just so I could immediatley determine it was copied OK, after I had done the original clone, I created a new .txt file on the desktop of the Acer, and that .txt file was not there after the 'restore'.

    Reddit suggested superclone as a better alternative to diskgenius, and I was going to go that route

    but after reading about it, it recommended not to back up onto a USB interface and I don't see that as an option with the VERO because it only has one disk drive.
