Dell Inspiron 2500 Battery

I got a couple of inspirons. Circa 2000 came with millenium. updated it to xp-pro, wanted wifi and ordered throuh ebay.a damaged one. Sounds like the charger is gone and the Dell Inspiron 1721 battery is shutting down as it has not been charged. You cannot change processor without changing bios. Have somebody with voltmeter test charger.. If you have access to another computer go to Dell and give #s on bottom and they will give you what it came with , my guess 512k max but they will tell you which processor. Get both numbers as they may have had a choice of AMD or Pentium 

Why can't you access the BIOS..? You should just need to press a button when it is being started up, just after the POST beep - the button is normally either [Delete] or [F2], and you might find that it is displayed on the screen (often in the bottom left) as it starts up.  Normally it would take longer for the CPU to heat up than 3 seconds, but if you aren't getting anything on the screen it sounds like it isn't completing the POST (Power On Self Test). One way to check whether the screen is FUBAR would be to connect an external monitor to the VGA port on the side and see what happens on that... If you want to check the PSU (which is basically the cable) then you can take the Dell Inspiron 2100 Battery out before you try to power it up and/or look at the "charging" light when you first power it up. 

Wouldn't I get something on the screen though, or the other lights turning on? Currently, only the power light turns on, while before all 3 of the "Lock" lights turned on for a second. I would think that it would take a little longer for CPU to overheat. The light turns off after only about 3 seconds.If you aren't hearing/getting any fans going when you POST, then it is likely that the CPU is getting too warm and it is likely that the CPU is shutting itself down (hopefully) before any damage is done....My DELL Inspiron 2200 battery laptop seems to have gone into an endless recalibration loop. I thought something was odd when it asked me to plug it in when it was fully charged, but I followed the directions (charge, discharge, recharge) and when I started it again it gave the recalibration warning.

I've been through this three times and I'd appreciate any suggestions. It occurs to me I use it pretty heavily and haven't defragged it since I received it (used). It could just need a new Dell Inspiron 2500 Battery, so battery recommendations would be appreciated if that is the case.First, I have changed your Discussion title to give a clearer indication of your question. For future reference, please be as descriptive as possible in both the heading of your Discussion as well as the post itself.Now, a continuous recalibration seems to be an issue with the battery. I am not one to provide recommendations on any hardware components. However, I would almost bank on a faulty battery.
