Last year I bought a used Clevo D27ES, without a battery. I figured I'd pay less because it didn't have a battery (that may or may not work anyway). Last month I ordered a new battery (generic, Chinese, I'm cheap). When it arrived, I tried installing it, but my laptop will not recognize it. It won't charge, it won't show up in power management, nothing.

However, I tried hooking a spare 80mm fan I had lying around up to the battery (used a multimeter to find the main connections). The fan runs fine, I left it for over an hour, and the connections measure a bit higher than the battery's rated voltage, which is good.

At first I thought that the battery was the problem, but now I'm thinking maybe the laptop has a problem recognizing any battery, and that's why it was sold without one. Is there any way I can figure out which one is the problem? If it is the battery, I need to RMA it as soon as I can, but if it's the laptop, I have a whole different problem.

Any help is greatly appreciated, thanks.

Well, if you feel up to it, pop it open and make sure no wires are loose/broken. If you don't feel like opening it, you could bring it to a repair center, but be prepared to pay upwards of 80$ an hour:eek:.

A bit old, but I worked out a fix for this. I ripped my laptop apart and started looking around with a multimeter, and decided that component X (i'm nearly sure it was a power filtering cap for the main battery power line) was broken or installed backwards or something. I desoldered it and soldered a jumper wire in it's place, and the laptop works flawlessly with the battery now.

I'm just hoping i won't need a filtering cap to smooth anything on the battery line, I can see why I'd need it on the DC In, but it seems redundant here.

That was pretty clever on your end. Nice catch.

I highly doubt it was a capacitor, had it been a capacitor the jumper would have made a direct short and crated a big problem
