Dell Inspiron 6000 A/C Power Issue
I've seen a couple of postings regarding the Dell Inspiron 6000, but none that sound exactly like my issue - or more specifically, like the issue my son is having with his 6000. As it's been described to me, at some point last year, his computer would seemingly not run using the A/C adapter, nor would it recharge the battery. However, the remaining charge on the battery seemingly was able to run the computer satisfactorily - until the battery was finally fully depleted of its charge.
My son happens to own two Dell A/C adapters (PA-12s), which when I check them on my Dell Latitude 600, they both are able to power my laptop, as well as to successfully recharge the battery. So, this does not appear to be a case of the dreaded A/C Adapter Not Recognized problem. Beyond that, I'm not sure what's the problem. The A/C power input plug on the laptop appears to be solid, and no amount "twisting and turning" of the power input plug seems to make any difference.
So, what we have is the ability of the laptop to power-up with only the battery, but the A/C adapter is not able to provide power - and all the A/C adapter we're using all seem to be in working condition, or at least have evidenced the ability to power up another compatible Dell computer. I'm going to solicit some help from work to ask a good Samaritan whether they would be willing to take the Inspiron battery home with them - and at least get that charged back up, and rule the battery out as the source of the problem.
Any other suggestions or approaches, based on what I've already described and tried?

It's worth testing the batttery, but in all likelihood it's the mainboard that is faulty.

Hmm, that sounds like it might be [ partly ] a good explanation. Yes, I think reconfirming the status of the battery is an initial "winner". Mostly to know whether to rule out something from that end, but from what my son told me, while the A/C adapter wouldn't seem to run the laptop, the battery seemingly still would. If I can get the battery re-charged and if it re-boots the laptop successfully, I think that discounts the "faulty mainboard" speculation - at least somewhat.
So, if the battery (as a power source) lies downstream from the A/C power source in the laptop, and we've already successfully ruled out the A/C adapter(s) (any of the three of them), as the source of the problem, that would almost suggest that the problem is somewhere in the middle? That would be somewhere at the on-board power supply level, but upstream of the battery and almost certainly upstream of the mainboard.
What's the best approach to diagnosing this (assuming I get the battery issued clarified)? I've disassembled these Dell laptops in the past, so I'm not averse to taking things apart, but what I am averse to is just "randomly" replacing components. I need to narrow this down to the most likely "suspect" and then execute a fix. I'm going to check on either the eHow or PC World, since they post-up some pretty good repair strategies (with pictures), but any further suggestions?

There is no "in the middle". If it's not the battery, and it's not the adapter, it IS the mainboard - there is no separate "internal power supply". It could be just the power jack - but if it is, the repair cost - if repair is even possible - will be around the same was what it will cost to replace the mainboard.

Darn it . . I hate it when there's no "middle" anymore. Okay, I was thinking of the power source for a desktop PC configuration. I keep forgetting that the A/C adapter is effectively the power source for a laptop. I guess the next step (for right now) is to solicit for a battery charge "jump" from someone at work.

Precisely this occured on my Inspiron 6000 when I had accidentally powered it in reverse polarity. It never turned on from the DC In Again. Only battery.
There was no solution to this.
Another thing similar occurs on my inspiron 6000D, I had resolved it by soldering a wire to the DATA pin from the motherboard DIRECTLY to the DATA pin from the power adapter. I Think that because my computer requires so much power, If it can not verify that the power supply provides sufficient power, It refuses to power-on for safety reasons. Such as overheating and melting cables. The data pin seems to have weak contact between the motherboard jack and the power adapter.
Too bad this thread is so old. Perhaps my information may help someone else who stumbles upon this old thread.

Try adapter 90watts 19.5V 4.62Amps..................see if it will give enough power.
If you try adapter 65watts 19.5V 3.34A............it has less power may not be enough power for Dell Inspiron 6000.

Hello
I have accidently connect wrong polarity to my Dell XPS M1730. Now it works only on batterry. No charge no pwer by the adapter
I think it is the reverse polarity protection on the motherboard is blown
Do you wich component on the motherboard is doing the reverse polarity protection?
Is it diode , pico fuse or othern and where it is located on the board ?
Thanks a lot
