I had this issue, RobAnthony's solution absolutely works!!! Ignore the warning from Dell when you flash this Bios that they don't recomment going to an older Bios version. I went from Bios 12 with a 0% battery not charging to Bios A09 with a 13% charging within 30 minutes! Here is the Bios A09 link again.
Do what I did ... and dump the Dell and get a HP laptop. Brilliant piece of kit. I have had 3 PCs fail on me before, other 2 were hard drive issue just outside of warranty, and guess what they were all Dells ... there will not be a fourth!
In 3 years my Dell XPS M1530 went through 2 power adapters, 3 motherboards, one keyboard faceplate (the first one carried a small electrical charge) one hard drive - all changed courtesy of my Dell warranty. Shortly after the last motherboard it just up and died anyway. Some reviews have stated the new XPS notebook line still runs a bit hot. So I bought some cheapie replacement and am regretting that too. Next time I will buy a Sony VAIO. The bottom line is if you're having problems with your M1530 laptop, it's quite likely it's due to a hardware problem - and if you sink money into it, it may still die shortly afterwards.
Was getting "AC Adapter Not Recognized" message in BIOS (BIOS was A12)...flashing the BIOS back to A09 now allows my adapter to charge new battery!!!
Its because a little red cable going from the power supply unit to the mother board has snapped. It tells the motherboard that you have the right power unit for the laptop. I've had two power supply units and both have done the same. I had to take them apart and solder them back together and now they work fine. Also another tip to stop the graphics over heating you need to raise your laptop cos ive had to fix mine four times, last time having to cook graphics card to repair it. Not enough air flows through the laptop, poor design!!
I have not had the "no charge" problem but my battery would not hold a charge shortly after 1 year. I told dell service and they said the battery was not under warranty.
I have had this "piece of junk for the price" for about 4 years. Since I use it plugged in most of the time I have not replaced the battery but plan to soon.
My experience has been far less than satisfactory with this "high end computer". Problems started shortly after I got it. It crashed bad (cannot remember what). I called Technical Support and they tried several things to adjust, nothing worked. I had to lose all my installed programs and put it back to the factory restore. Then later the motherboard and memory had to be replaced. Then another motherboard and memory. The third time the motherboard and memory went out I had to send the computer in to be repaired. Dell's next day warranty is not worth the paper/bytes it is written on/with. I was without my laptop for about 8 days.
The bluetooth keyboard quit once under warranty. They were good and quick to replace it and they replaced the bluetooh mouse at the same time since they are sold as a set.
With all the trouble I have had with this XPS 2530, I have decided to never buy another Dell and I am not afraid to let others know that they shold not buy Dell products.
When the extended warranty expired Dell called and asked me to renew. When they told me the outrageous figure, I told them when this one quits again I will go to Walmart and get an HP with more features, bigger hard-drive, more memory, for less $$$$. I recommend that others to do the same.
