Well hey there folks. Been awhile! We have some cool news for you Acer Chromebook School districts that are self-insured, or self-repair.
We tore down the C740 and the C720 and compared them side by side. We noticed some compatibility, and a few differences. Some may criticize Acer for not changing the model much, especially in comparison to some of the other manufacturers. My mama says " If it aint broke dont fix it". In our opinion, props to Acer for stretching this design out a bit, as it will help the schools keep these devices in circulation longer and help with budget constraints!
Anyway! Lets get down to it:
The LCD panels are the same. The Batteries are compatible. The AC Adapters are compatible. All the plastics, the palmrest, the trackpad, the motherboard, basically everything is compatible!! That's right, most of the C720 parts work in the C740 and vice versa.
Here is a bullet list of whats different:
C740 Hinges are beefier, using same screw holes, but the hinges continue to the top of the display to another screw hole.
C740 Processor is more efficient, boosting battery life by AT LEAST 30 minutes(some say over an hour), while using a 30MAH smaller battery cell capacity! Would a new C720 Battery, with a C740 motherboard = even more battery life? You should try it out!
Auto-Brightness ambient sensor seems to have dissappeared?! We are still figuring out if they deleted it or moved it somewhere sneaky. At this time we don't see one.
Wifi Chipset is different. Most of the other surface mounted components look exactly the same, however the onboard wifi chip, and the chip layout around are slightly different. Could they have improved the range? You'll have to chime in on that.
C740 Back cover has a brushed metallic finish on LCD Back housing, and the palmrest color is just barely different.
All in all the differences are minimal. This will help with parts availability, and again should help schools fix these on the cheap.
