Hello:
We have a 15 year old son who we want to limit his computer activity
after school, while he's home alone -- before we get home from work.
We used to be able to just use a key to lock the keyboard with old 386
and 486 machines. But they don't make this like that anymore. Now we
have two an AMD 1.2 GHz machines. One is running Win2000 and the other
one has WinXP sp2 on it. Is it possible to "lock" these two pc's?
Thanks in advance for your help.
The same type of key-lock used in those older systems could
also be put on yours. You'd either buy the lock (or take
one out of an old 486 box as you mentioned) then drill an
appropriately-sized hole for it wherever you want it. Then
the contacts on that switch are wired in series to the power
button, or there might be a chassis intrusion header that
could be used instead, after a bios setting to enable the
chasssis intrusion feature (and/or wired into existing
chassis intrusion switch).
HOWEVER, as others have mentioned there are quite a few ways
to circumvent almost any practical and cost-effective
deterrent, if he were REALLY motivated to get it running.
Then again, an old used computer can be found for cheap or
free, what's to stop him from fishing one out of the
dumpster and not needing yours at all to do (whatever)?
Complete prevention of use might have drawbacks though,
since a computer is a pretty basic educational tool these
days it might be better that he be exposed to (whatever you
fear) while still under your supervision so you can help
guide his choices now, helping to promote healthy attitudes
and discuss these things... besides that, the forbidden
fruit is always the sweetest.
