I know there are a lot of known suspend issues, but this is not one of them, I believe. If you have to do this every time you turn on your computer, its possible your CMOS Batte.
This error only occurs after waking from suspend. Learn how to address a Checksum or a Date and Time Not Set error. If I put the computer to sleep, upon waking it, I'll get a "CMOS checksum error," which'll cause the BIOS to reset immediately (Secure Boot = Enabled is the default value it resets to), which'll cause the BIOS to not detect my boot drive whatsoever, so I need to go to the BIOS and disable Secure Boot again after force shutting the machine down from its error state. The CMOS battery is practically BRAND NEW.Īfter disabling Secure Boot, everything works absolutely perfectly with this computer EXCEPT: This happens when the CMOS backup battery fails (and CMOS contents are lost), or after a BIOS.
I'm running Xubuntu 18.04.01 LTS on an HP Stream 14 (14-CB108CA). A checksum error means that the CMOS RAM contents are invalid. Please check your BIOS setup options to see if they change.' this also. The CMOS will be reset to the default configuration and will be rebooted. The only other existing post about my issue ( Ubuntu 18.04 on HP Stream 14 - Suspend Produces Checksum Error ) doesn't help much. if your laptop shows:The CMOS checksum is invalid. A battery that has become discharged (the computer has been off a very long time). First post/first time asking anything in any forum ever! and a checksum error is issued by the BIOS.
