When you begin to boot the system Tap the F8 key. This will give you several options for booting Windows in different modes. Select Safe Mode and boot the system.

The closest diagnostic code that matches what you're saying is the 4 (continuous beeping). This is a video module failure or system board failure. The T41 does not have a separate video module which indicates system board failure. If you can locate a T41 with a good system board on eBay for less than $50 then you could attempt a repair on the system. Otherwise the system is dead and its cost is greater than its value.
You can try the steps below.
Try removing the battery and plugin the charger and try turning on.
Do you see any thing displayed on your screen when you switch on?
Please mention the beep pattern, 2 beeps or continuous beep.
Hope this helps. Good Luck
The IBM Thinkpad has a very strong security system.
you are seeing a lock symbol when booting then somebody has set the supervisor
password. If you can't remember it or guess it (try "password", "admin", "pass", etc)
then you need to find the person that set the supervisor password.
the supervisor password is set the T41 is very well protected and it
can't be reset by removing the laptop battery or CMOS battery.
is a way to read the password from the protection chip but this is very
complicated and requires taking the laptop apart and building your own
I had the EXACT same problem with my T41. Mine issues were caused by overheating from too much dust/dirt inside. I took it completely apart, blew it all out with a compressed air, and reapplied thermal compaund to the processor/fan...works like a charm now. Definitely start there...it cost $4 for a can of air and $6 for thermal compound and about 45 minutes of my time. It's better than spending a bunch of time and money replacing components.
Check that the hard disk is in working order.
If the hard disk will not spin up... sometimes the system will just shut off.
It may be a bad motherboard.. usually a damaged or failing capacitor will cause the system to not stay powered up long enough.. capacitors usually create a steady flow of electricity... if it can't hold a steady charge it will behave as you've mentioned.
