Recently a friend’s laptop stopped working. The screen would go black and display only the message; “Time-of-day clock stopped”. The error occurred before the start-up sequence reached the boot options. After some research I discovered that it’s actually a common problem for the Dell Inspiron. I also learned that a little coin cell battery needs to be replaced on the system board in order to fix the problem.
It took me about an hour to take the laptop apart to get to the battery and another hour to put everything back together again. Fortunately, I didn’t mess anything up. Afterward, the laptop started up nicely and asked me to enter the BIOS setup to reset the system’s clock. After I did that, Windows started up normally and as far as I know, everything works perfectly.
Without the step-by-step service documentation provided by Dell, I probably wouldn’t have gotten it done.
Here are a bunch of pictures that I took, documenting the process;












its the best reply in short ,i will try for the seame for my laptop

Thanks a bunch it worked out great for my laptop. I wish everything i needed help on had pictures to show me what i needed to do.. You rock man!!!
u r the best
thanks u r the best ….
you can do this without removing the display, and also make sure to get a compatible clock battery from a computer supply store or website, not all cr2032 battery’s are totally compatible, cause I have done this many times and figured this out 🙂
I can remove the casing to get to the battery
I have to get the CMOS battery (clock battery) replaced on my dell inspiron 1545. I have a guy that is going to fix it however rather than bringing him the computer, having him take it out and then bringing it to a battery store, i’d rather get the battery first and then bring him both the laptop and battery. But I have no clue what kind of CMOS battery it is.. are they all the same? one size fits all? I honestly have no clue.. ive been googling for hours and cant find anything! Please help!
Click on the last picture on this page to bring up an enlarged picture containing the battery. It is a CR2032 flat, button type battery. Any CR2032 battery should work, and you should be able to get one at your local Walmart, electronics store, or even grocery store.
Here’s a picture of just the battery: http://media.digikey.com/Photos/Panasonic%20Photos/CR2032.jpg
Any CR2032 should work–it doesn’t have to be Panasonic.
My daughter board only appears to have one screw but it won’t come out. Is it somehow hidden? Please help!
Hello to all,
may you please give me a tutorial on how to fix the Dell inspiron 1545 battery charger.
Not charging battery . I tested the output voltage using a test meter: the 19.5V is present only on the middle pin .
This is awesome it worked for me!!
Isn’t it possible to replace that battery without to fully take all the laptop apart? I meant, is it possible to replace it directly from the underside?
Thanks in advance for your response!
Regarding the CMOS battery, are ther other bootup issues aside frome the TOD clock? My 1545 starts the bootup process but before the system reaches the login/password screen I receive a system error corrupted files. I have tried my WIN7 booting up with my System Recocery CD and get the same error.
nic one it worked for my pc
