Routinely 'recharging' the battery at 40% may well account for it's sudden
death after 70% battery life usage, depending on the type of battery it is.
I would recommend fully discharging the battery, and then fully recharging it.
To fully discharge it, make sure /all/ applications are closed (including
those running from the notification area). Disable hibernation. Disconnect the
A/C power, and let the machine sit until it powers down.
Then, plug the A/C in and let it charge while the system is powered off. Refer
to your users guide for the notebook for the recommended full charging cycle,
but it's probably a few to several hours. "Overnight" would be a good charging
cycle.
Also, depending on the current load required by your notebook, it's entirely
possible that a 30% reserve in the battery is simply not enough 'juice' to
keep the notebook powered up. This would be particularly true with systems
that have 17" or widescreen displays running at higher resolutions, or
high-speed internal drives, or any external USB connected resources that do
not use external power.
But, also do the uninstall update test to verify that it's not being caused by
any updates that were installed. I don't think it is, and even less so now
that you've described your operating conditions, but it's not impossible that
something in an update has affected the battery monitoring utilities in your
notebook, so do be sure.
