trackpad/pointing stick not function after battery loss

Helo,

have this laptop that got used on refurbished market
that i like very much but showing age slowly

it function well with devuan,
would have two minor complaint

1. the battery bridging does not function properly (that may be an issue of the aftermarket "external" battery), hence when the first battery depletes, the laptop shut down.

2. in case of such an event, after restarting the laptop,
the touchpad and pointing stick is no longer recognized (bit odd).

the "solution" is to boot into windows 10 and then reboot, again into linux/devuan, and the touchpad/touching stick is bacck.

maybe you know of more modern solution to the second issue,
thank you very much.

this is xinput with the touchpad and stick function

xinput
ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

    ↳ BRLTTY 6.9.1 Linux Screen Driver Keyboard id=14   [slave  keyboard (3)

with the nonfunctional trackpad/touching stick it goes only until 10 or 11 or so, not showing SynPS/2 Synaptics TouchPad and TPPS/2 IBM Trackpoint.
this had been described on other forum, but have not found a solution yet, besides the incursion of booting into windows first.

Re: trackpad/pointing stick not function after battery loss

Old Toshiba laptop here. The trackpad occasionally, seemingly at random, stops working after startup/reboot and is then found to be disabled in the UEFI firmware setup. The solution is re-enable it in the setup. Presumably buggy firmware or ailing on-board cmos battery.

Re: trackpad/pointing stick not function after battery loss

If the hardware disappears in xinput (can also check cat /proc/bus/input/devices) then it's completely gone as far as Linux is concerned.

Back to basics: Are you sure there isn't a hardware/firmware level way to disable/enable the trackpad? There is on my laptop, it's a Fn+F8 key combo that is handled by the firmware directly.

You can check sudo dmesg for any messages about the device being disconnected.
