Had to change my rating these have been a nightmare.1. When we reinstall the laptops install Home, not Pro. After some playing around and a hack on the Internet we were able to get past that.2. Get one machine completely loaded. Power it off power it back on, need to enter the date and time, the second time. Update that and now get the BSOD.3. Unplugged two laptops and the battery went down to almost zero within a couple of minutes. The battery showed Excellent in the BIOS. Ordered 4 new batteries, I had to deliver two of these by tomorrow.I do not plan to buy any more machines from this seller.
