I have my laptop plugged in and "charging". The red battery light is flashing and when i open the power settings the battery doesn't even register. I also noticed a serious decline in performance once this started. I thought it was simply the battery died so i replaced with a new one with the same results. Please help.

Try removing the battery and just use the AC adapter. If the laptop functions normally then you have a problem with the battery charging circuit . Either your battery is defective or the circuit that charges it is defective ( meaning the system board).
That means either the battery is no longer good anymore or the laptop is unable to charge and/or recognize the battery. Try cleaning the contacts of both the battery and the laptop when everything is unplugged and powered off with alcohol and a q-tip. But usually if a laptop is not charging the battery then most likely you will need a new one
This could indicate a bad battery. Try removing the battery and powering on the laptop. If the power LED remains white then you have a problem with the charging circuit. That means your battery could be defective or the battery charging circuit on your motherboard is faulty.
If the battery light flashes red, this is usually an indicator of a bad cell in the battery or the battery is not being charged. This could be a power supply problem, a battery problem or a power adapter problem on the motherboard (The piece mounted to the motherboard that the power cord plugs into). Laptops are becoming notorious for this last problem.
the battery has reached its expected life, you need to replace it. If it is under warranty, you can call dell and have them replace it. You can still use you laptop with the wall power/charger plugged in, remove the battery to get rid of the flashing red/green light.
Hi, when u get power on of your laptop .u seen Red/orange light blink 4 times on front panel.it means your laptop battery is not getting charge.please get charge for minimum 6to 8 hrs & then try to on .if y u laptop battery is get charge u r laptop will started on (also confirm your A/c adapter is working .green light is display on front panel it indicates charging on )
If you are using known good batteries, and you have the most current BIOS Flash, then it is likely a failure of the charging curcuit on the motherboard. The flashing Amber (Some people see it as red) led indicates a failed battery
The Multiple good batteries, I assume have been recently purchased, because computer batteries are consumable and are rated for 300 to 500 charging cycles before they wear out.
I replaced my 700m motherboard with one from Ebay for about $170.00 about a year ago.
sounds like a dead battery. Plug the origional charger into it and the front led (below the flash) should flash red. If the red led in the back of the camera flashes or stays lit, then you have the wrong charger plugged in. (the camera won't power up if the back red/green led is on when plugged in)
