This is the second time my laptop has suffered the exact same issue:
- The laptop turns off when the battery fails (not a windows shutdown, just power loss)
- On startup, the trackpad and trackpoint dont respond, but the keyboard is responsive enough that I can log in.
- After login, even the keyboard is unresponsive.
The funny thing is that only those part of the keyboard that need OS interpretation don't work; those actions that signal the board/Bios directly work just fine. The thinklight toggle indicator shows up on screen correctly when i toggle fn+space, and the power button works fine. Other than that, everything else is just *dead*.
The solution seems to be to use windows recovery to go back to the last restore point.
From this, it seems to me that Windows has horrible durability when it comes to power issues. Or maybe I've not configured it properly. Whatever the issue, I know that the aftermarket battery (something that mimics a Sanyo 45N1023 **badly**) has to go, as it loses power around the time it indicates it has almost 20%.
Is this a common issue with windows 7? How can I ameliorate it such that post such a power loss, I don't get an unresponsive system? Or it prevention the only way?
Note. I've been off Windows for more than 4 years, but from the little I remember, the situation was supposedly much better.
