Can anyone who has actually performed this replacement discuss how difficult or easy it actually was? Did you use only the tools listed or was the heat gun necessary/useful? Does the tablet with a replacement battery accept a full charge and fully discharge before shutting down? Does the referenced glue that Alex mentioned actually make this replacement as unlikely to be successful as indicated. I ordered 2 new batteries from Chinese vendor via Ebay. They both arrived with comprehensive tool kits to execute the replacement including suction cups for the screen. I have a heat gun and will most likely do this in the next 2 weeks on 2 Venue 7840’s. I’ll re-post with results.
