From a_gondhaleka to Hank94170. You asked: When was the last time you changed the cmos battery? Answer: Never. I think it is still the original battery. However, I have tested it, the battery shows 2.87 volts.

I changed my "setup settings" : the F2 key and now almost everything crashes. i need the original settings in the different categories.

Unplug the machine, remove the CMOS battery, wait a 15 minutes
, replace CMOS battery, reboot, open BIOS, Set time ONLY. Save and reboot. That begs the question, Why change the BIOS setup?

Schematic for toshiba p200d-12kbecause i need to change the cmos battery

The CMOS battery will not prohibit the machine from powering on. If you're prompted before boot about the CMOS battery, you should be able to press whatever key-combination it asks for to move forward to boot. Otherwise, you have a separate problem.

When I turn off my laptop, my clock on the task bar stops. When I turn it back on, sometime later, it starts from when I turned ot off.

The real-time clock is maintained by a chip on the motherboard. It derives it's power from the laptop battery but there should also be a small 3V battery inside the laptop to maintain the clock and the CMOS settings in the event of total power loss. This battery should last at least 5 years and possibly longer if the main battery is kept charged.
In order to see if it is a Windows issue, start up the laptop and go straight into the bios setup. The clock will be displayed here and if it is the the same time as when you switched it off then the problem is hardware related, possibly with the CMOS battery. If the time is correct here then let the laptop boot into Windows and check the time again. If the time has now changed then the problem is with Windows, in which case you may need to check for possible viruses.
If you think it is the CMOS battery then it os not likely to be easy to get to it. Look on-line for addition info for you particular model. If you manage to get out the CMOS battery then check the voltage on it - it should be above 2.5V for guaranteed operation.

Cmos battery dead - needs to be replaced

Sounds like you need to change the CMOS battery, the time being wrong everytime you boot is a good sign but also it losing its settings in bios is also another sign

Boot problem

Updating the BIOS could be the solution, but, let's leave that until last - if you get it wrong, you'll stuff up your machine (mobo) for good.
Don't worry about the CMOS jumper, it is there to clear the CMOS memory, but I don't think you need to do that.
Can you get into your BIOS during start up OK? (usually by hitting F8, F2, Del one of these keys or similar during start up, it should tell you which).
If you can navigate your way through the BIOS settings ok, don't change anything you're not familiar with - another place you can do damage, and somewhere towards the end, where you have to option to exit BIOS with or without saving there should be another option like "Reset Defaults" or "Load Optimal Settings" or "Set Last best Settings" or something like that.
Click on this then exit your BIOS. Your computer should restart.
Make sure your new memory battery you put in is up the right way, if it's upside down it could be causing a short - the usual way is positive up, that's the whole flat face with the writing on it - the insulated button side is negative (down).

**.The best way to acknowledge contribution is to rate it's relevance.**
