Question about Dell Inspiron 6400 Notebook
My computer says that it is plugged in , not charging and gives the error code 3600:0749 when i ran the diagnostics. i have the original adapter that came with my computer. it is only 6 months old. i have a dell laptop.
If the system is only 6 months old, then it should be under warranty (Minimum warranty at Dell is 1 year) So contact technical support and let them assist you in finding the failure (800 624 9896 USA)

Your problem has not gone unknown, you and probably a few hundread dell customers are having thes same issue and it happans right around their waranty expiration period. intresting enough apears to be a flaw on the physical motherbaords power adapter location, although it dosnt seem to be that serious from my inspection of simaller models. they complainbts show it is a flaw and dell shuld stand behoind this. have a read at this site if you have the time
once you have varified the problem might be good idea to click the i have the same problem link to help others with the issue. the more people who bcome aware then faster dell will correct or issue a recall for the problem baords. maby eavn replace your whole laptop at little or no cost to you ;). the fact is that theirs several issues with laptop batteries charging, some seem to be the wrong type of crapy oem charge controllers. a good idea is to get a replacement power supply from credited and superior source for power protection. and maby you wont be a statistic with the rest of the failed mother boards. please see this link when you have some time .
once thing i saw bellow is a power adapter not oem that will protect your laptop from spike issues and power fluctuations at least better then the oem one.
$19.99 to protect a 1,200 dollar laptop sounds like a good investment. but keeping in mind its only an option. if i was selecting one id look for good protection and circuit monitoring. this is an example of that. and will eliminate the other issues your having.
Input: AC100-240V (worldwide use)
Output: DC 19.5V 4.62A
good luck with it. note: the power in watts can be higher then your old one this is actually a good thing. but you cannot be lower in amp. then the required amount. this is up to you to verify the laptops power parameters but this should work out of box for you, as it;s made for your laptop exclusively ;)

-check the system battery information and charger information of the computer; restart the computer, while the computer is booting up, press F2 repeatedly; check "battery info"
-if it stated ac adapter = unknown device ; update the BIOS (-visit support.dell.com
-click on drivers and downloads
-click or choose by service tag
-download the BIOS and install it on the computer)
-check information after updating; if same message AC adapter = unknown device; call manufaturer for a replacement AC adapter, if status has changed it is a battery problem or motherboard, contact manufacturer to test battery
