I have brand new Inspiron 1520.
Battery fully charged, when I unplug the charger from the wall, but let the plug in the Inspiron for a while (let's say a night), when I startup my computer, I get the message "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" (needless to say that the power adapter IS a Dell 90W...).
Unplugging and replugging the adapter solves the problem.
I have the same message under Windows when I unplug the adapter from the wall, leaving the plug on the computer side while the commuter is running (to go from one room to another for eg.)
I have contacted Dell support, they asked me to reflash the Bios (already done) then, they sent me an new power adapter : same problem... now they are talking about a mainboard replacement !
While Googling for a solution I've seen this is a very common and long term issue on Dell computers.
Are there any people around here that had the same issue and managed to have Dell correct it ?
Dell has no way to change an order placed by a salesperson using incentives. They switch a component on the ordered system to a lesser one that isn't selectable from the website and then charge more for the one already purchased. Off Shore CS is a con job.
Is it the battery or the AC Adaptor - or worse? Dell Inspiron 1505 battery shows 100% charge but unplug the AC Adaptor and it dies instantly. Won't reboot on battery alone.
Have tried a different adaptor (both are Dell), but since battery says it's at 100%, that doesn't change. Of course I'm 2 months past the 1 yr warranty... but it's the uber-expensive 85 WHr 9-Cell Smart Lithium-Ion Primary Battery for Dell Inspiron E1505 Laptops. I'm not really wanting to spend $300 to replace the damn battery when it's only 14 months old.
