Hello everyone,

when I try switching on my Dell Studio 1535 Laptop, the machine does nothing, exept a flashing battery status light as long as I press the power button.

The battery is fully charged (according to the built in indicator leds). Its a 85 Wh 9 cell battery.

If i wait a little and plug in the AC power, the battery LED indicates a normal charging process.(constant light, than turns off as batt. is full)

Again if I try to start the Laptop unplugged to the charger it doesnt do anything, not even a flashing LED.Only with the charger plugged in, the battery status light flashes standard green as long as I am holding down the power button and then again nothing.

Has anyone ever experienced something like this? Or does someone know where I can look up failure codes for the LED-behaviour? Couldnt find anything in neither the normal manual nor the service manual.

Any help would be appreciated!

Thanks so far.
