If you see any corrosion inside the slot clean it up with a toothbrush and alcohol. Nothing seems to work. The battery icon indicates that it is not charging. Keep track of screws. Once replaced, I plugged in the power cord.

After a year of using my wirwless without abuse, i found some annoying problems with its CMOS battery, touchpad, internal keyboard and even its earphone and speaker sockets… Damn it! Thanks for this guide. I hit my laptop inspiron N it was a soft hit but after I did it my laptop screen went white, so I turned it off and back on and it was the same with 8 beeping sounds.

Took it apart, inspect the monitor wire, looks good. So I tested with other new memory. Help would be greatly appreciated Check memory.

My main wieeless is: I got a 3 beep code and then it would not bootup or even start I have had this problem several times and for some mysterious reason, everything would work fine! I think this laptop has a regular CR coin battery which you can buy in any convenience store. I think you can see that on the picture. I turned on the power botton and it lights up a few seconds and goes off. Many thanks for putting these very good instructions up.


You have done a good job by giving the steps to dismental the laptop. I remove battery, follow your instructions and dry it. I only had a problem with its main external battery and nothing else…after 8 months of use which i got it replaced through its warranty service for free. It power adaptor and the batter are working fine but the laptop does not switch sell.

I have a loose connection i think because the webcam gets detected when i keep my screen at a particular angle. Also, make sure the AC adapter is good. Probably you had purchased wrong memory type. I have know idea where it goes. You cannot disassemble the keyboard for cleaning. I replaced the wirelses drive myself. Mine is 6 months old….

I then took out the battery while plugged in and it died again!


After I got it back together, the laptop would not power up still del it would finally with the battery installed.
