Comment 107 for bug 1774950

I've noticed a similar problem with a Lenovo laptop with an Intel CPU, Intel Haswell graphics and an SSD. One difference is that suspend works fine the first time the lid is closed. Upon opening the lid, it comes back up and I can unlock the screen, but the touchpad no longer works. If I close the lid again, it never goes all the way into deep sleep. The symptoms are that the led that slowly blinks when it enters hibernate stays on all the time, so the battery drains quickly and it stays relatively hot. A hard reboot corrects the problem. This only appeared after upgrading to 18.04. The kernel version is 4.15.0-39.
