70W power supply for a 90W dell c840?!?!?!?!?!?!
 I have a dell C840 that requires a 90W power supply. I have a 70W power supply available. I was told by a tech that it would be ok just hit the requested "F" key and it would be ok. What would actually happen?

the ac power is insufficient to run it properly
run from the battery so it looks like you need the correct power block

hi
You Need to use the correct wattage for the laptop otherwise the computer will not work properly I suggest you forget what the so called 'tech' told you and get the correct power supply for the laptop As my power supply died a couple of weeks ago and i tryed the same thing -- doesn't work!
