What's going on ,4 hours sleep costs 20% battery

[yonghong]

Even worse, shut down ,restart then put it to sleep, 1.5 hours cost 15% battery ,and take it out feel hot , do I need return it?

What does the Sleep Study say? I would do a factory reset and test it again before I would return it personally....

chances are your battery is dying a slow death, unfortunately. I recommend when you replace your battery, charge it fully for 2-3 hours don't play with your computer then and always remember... always plug the power adapter into the socket first, then plug your device in.

maybe it's sd card ,as above people ,I took out the sd card last test, and sleep 1.5 hours cost 15% battery

It is either the SD card or possibly a bad keyboard cover as both are USB based....

Also I should have asked, do you have a USB Wireless Dongle (for a Mouse) in the USB Port?
