Thinks to try:
Try a different browser on your laptop.
Try your laptop in a different location(different high speed connection like coffee shop or libarary)
Try your accont on a different computer

try removing the battery and just use plug power only if it boots normally then change the battery and the change the power supply unit as well I would just start with the power supply unit first then see if the battery charges up if not the battery is bad replace it. Now if the computer will not start with the battery removed then you have a power supply issue.
Change and replace it. Hope this helps. Also when computer lap top get hot they will shut down to protect the computer wait and let it cool down then try to restart your computer. If this does work and the lap top restarts normally get a fan cooler that is USB powered and the lap top sits on top of it. Also make sure the fan is running and is not stopped. Clean and dust it out once in awhile. I hope this assists you with your problem. John

Read the same topic "dell ac adapter can not be determined" on Dell.com and getsatisfaction.com. May it will help.
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation"
AC power adapter can not be determind

Dell Inspiron 6400 AC Adapter

Since most newer lap tops and note books use Li-ion batteries, they (the BatteryPack) have a built in chip to keep the charger from over charging a depleted battery, one that has locked itself from being charged. This is a safety feature to prevent a fire from a hot battery that may be overcharged. This feature locks the battery when the internal resistance gets too high and the battery pack falls below 3 volts per cell.

Try this for laughs, take the battery out of the lap top and put it in your freezer for about an hour and then place it back in your machine and see if it will begin to charge. This works sometimes as the cold slows the charging down to where the battery may recover. However, it will still be a low use battery as over time they loose the ability to be recharged to a full 100%

The worst is that you may have to buy another battery. If you do avoid buying used batteries as some one else is trying to sell you their problem.

your problem is that your missing drivers thats why its not seeing it. you can get the drivers from here if you donot have a disk with the needed drivers

try contrl alt del at same time hold for 5 sec if that does not work take batt out hope this helps

It is very likely that the batteries need charging, tip, charge them in a separate charger, if the batts are low, the scanner asks for confirmation to charge them (it is not automatic) and with no display you won't see this message and will forever keep trying to charge them without confirming "yes" for the scanner to do it!!.

Dear customer,                  You can try *#7370# and *#7780# for resetting or formatting your mobile. Also the "Restore factory setting" will help too. Thank you.

take out battery or unplug from wall open cpu or lap top and remove the inner memory batt. this will kill the last mode it remembers thats why its stuck. leave out for 2-4 hrs for best results. min 1hr and a half

Replace Battery.
