Dear all

I got a notebook that run out of battery on the mother board. Which
means, every time it reboots, or shut down and start again, the system
time goes back about 100 years.

I can workaround this issue by running ntp client upon booting, but this
notebook I used to take it everywhere (I am a heavy traveler) and I
cannot connect to Internet in many situations. Manually adjust clock
every time is very troublesome too. The local repair center told me to
fix this I need to pay the price close to a new notebook computer to get
the motherboard replaced, because battery cannot be replaced separately.

What brand of notebook is it, so the rest of us can avoid purchasing one
like that? Or maybe the repair shop is wrong and you can replace the
battery.

Apple iBook. I think it is designed in this way intentionally, to force
user to upgrade later.


I think there probably exist some sort of external system clock device?
That for example can be plugged in PCMCIA or USB slot, provide the
kernel the right time when kernel boots? If there are such device then I
can solve my problem. Otherwise I probably really need to spend a lot of
$$$.

You could write scripts to save the time in a file at shutdown and
restore it at startup. It won't be the correct time, but at least the
time won't go backward.

That's a very good solution. In fact, I managed to replaced motherboard
with another used motherboard at only a few $$$ by negotiated together
with a friend who knows a better repair shop.

Thanks for all the information and hints!
