I have a 5150 Inspiron that upon pressing the power button, the battery indicator flashes amber 10 times. No other lights light up. Machine won't boot -AC adapter plugged in
When i remove the battery, nothing happens, the machine won't boot. -AC adapter plugged in
Verify that the LED on the AC adapter is on before you plug in the notebook end. If it's not, replace the adapter. If it is on, then the mainboard in the notebook is faulty - and on a system this old, the cost of a board replacement (on the order of $350 or more) makes a new system a better idea.
