Correcting a non-booting Dell Inspiron 1525 or 1526

The Dell Inspiron 1525 and 1526 laptops have a strange design issue. If you have one of these units that will not boot up this may be the solution. Check out the status lights, if the num lock is on solid and the caps lock and scroll lock lights are flashing then the CMOS battery needs to be replaced.

Here are the statur lights circled. Most machines will continue to boot and just display an error message stating the CMOS battery is low or maybe they will loose the data and time but these Dell models will not boot at all.   It may sound strange that the laptop will not boot is just a CMOS battery is low but its right. These units use a standard CR2032 lithium coin battery as seen here.

These are available from most stores that sell watch batteries for about $3.00  Getting the battery is the easy part installing it is another thing.  Dell’s design of this laptop series is a bit odd. To get to the battery you have to fully disassemble the laptop.  The battery socket is located on the bottom center of the motherboard but is not accessible through any cover.
Here is a link to the Dell website page on changing the CMOS battery -  Dell web site.  To change out the CMOS battery you will need about 30 minutes and a small jewelers Philips blade screwdriver. Leave us a comment if it helps you get your machine going again.

  2. Followed all the instruction and it completely resolved the issue. Thank you for the blog! It did the trick, which means a happy customer..

    So puzzled as to why Dell really dropped the ball on this one..
    No CMOS battery = NO Boot = Stupid.
    Fully Disassemble Laptop to get access to CMOS batter on said laptop = Even more stupid!

    Seems like a money making scheme to me.

    Anywho, thanks for the instructions.

  4. I am experiencing a similar problem with my 1526. I’ve attempted loads of things in order to correct this and nothing has changed…I have ran an LED code test and it FLASH-SOLID-SOLID. I have done some research for this and I’m getting conflicting stories. One tells me that it does not detect the processor, (which I know for a fact to be good). I have a (mostly) similar laptop model…the Inspiron 1501 with the same exact socket. I’ve had swapped processors into the laptop that I KNOW works and the said processor boots and runs perfectly. Another site says it’s a memory error…I’ve reseated the memory sticks multiple times…same results…Reseated the CMOS battery….Now I can also confirm that the monitor is also good..I’ve ran that test too. I have replaced the motherboard with a brand new one. Something is amiss…any help would be deeply appreciated. Thanks

Tell me what you're thinking...
