If you want to keep Acer Softwares, you could try migrating the whole disk to SSD with MiniTool PW Free, if you don't mind loosing few unused Acer programs or SW, you can take the traditional approach, it will be clean, you don't need to worry about drivers as Windows installation will take care of that and you can still download from Acer support site, if you need any.
You can also download some programs like Acer Care Centre and Acer Quick Access from Acer site.
As I mentioned in a different thread, this is what I have found for the original cover.
Quick search for the part number shows that the acer part number is: HC.70211.08A
Not sure where you are are located.
In the UK:
They used to have over 100 units in stock back in January, but now showing 0 inventory, not sure if they will restock. If you are in canada, you may want to call them and see if they can order you one.
I know in Canada Staples also carried them, since a friend of mine bought the phone there (in Montreal), and picked up the flipcover at the same time as an extra option. It was about $20 about 3 months ago. I don't see it on thier web site however.
USA, I have no idea... Maybe some Acer support person can provide guidance. Considering the phone doesn't even show up on Acer.com web site yet, I'm not too surprised that no accessories are being sold for it yet in the USA.
Considering it sells separately for anywhere from €20 to €35 (which is about USD$22 to USD$40), I'm not sure it is really worth it as a separate item. But to each his/her own.
I've had it now for close to 5 months, and honestly, I don't think I'd miss it if I didn't have it either. It's a nice gadget, but far from ideal in many ways. The fact that you need to open/close the cover to even see anything, kind of defeats the purpose of the smart window. Would have been nice if you could awaken the smart window by double tapping it or swiping. But having to open/close the cover to even see the smart window is kind of pointless. Yes, the battery charge is nice to see at a glance. But there are many apps for that. I use Nova Launcher instead of the default launcher, and I use the Transparent weather clock by MACHAPP from the play store, and I have a wiget on main screen which also has my weather, temperature and even battery charge, and it's usually what I use. Anyhow, everyone has thier own preferences. Overall, I have no real issues with the phone, it has been great (and still is), and for the price at the time, it was hard to beat.
It is actually a picture sequence at https://www.ifixit.com/Device/Acer_One_10_S1002-145A. Select the motherboard replacement and look through the sequence. The step 3 picture shows the connector I found a problem with at the bottom of the picture. There is a special plastic tool for wedging the unit apart. I used a plastic orange peeler that is about the same. The only other tools needed are a Philips screwdriver, care, and patience. The connector has a little clamp that comes up from one end and it to go down over the ribbon cable to hold it in place. There is a fold-over in the ribbon cable that I moved slightly and retaped to make it less prone to pull out of the connector. Good luck.
Turbo boost doesn't mean overclocking. It is called intel turbo boost and it is automatic. Please send screenshot of the Predator Sense version you are using now.
Edit: 6gen mobile CPUs can't be overclocked except 6820HK. Also 3.5Ghz is for single core. For 4 cores it is about 3.2GHz
To get maximum performance from your computer's battery, we recommend that you initially condition (fully charge and discharge) your new battery a few times during the first several weeks of use, to let it reach its maximum rated capacity. Over the long term, use the battery at least once a month, even if it was kept in a cool, dry place for storage, but avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for a lithium-ion battery than one complete discharge, and recharging a partially charged lithium-ion battery does not cause harm because there is no memory. Closely monitor the battery charge. When the battery charge gets low, change the battery or connect to AC power immediately to prevent losing any unsaved work.
