Hi, My dell inspiron 1150 won't turn on anymore, no led lights, no spinning up of the fan or hard drive.
This occured after I plugged in a flash drive, the screen went white and the power just cut out, the battery was plugged in as well as the power chord. Here are steps I've tried:
1. Removed and replaced memory modules with spare working ones
2. Removed DVD-ROM, Hard drive, and battery
3. Plugged in power cable, the light on the power cable stays on but
the laptop stays "dead" 4. Removed the keyboard, heatsinks to examine chips, no visible sign

A fast check to determine whether you have a problem with the power
adapter, power cord or the laptop's battery is to turn off the laptop,
remove the battery, connect the power adapter, turn on the laptop &
see if it works. If the laptop works directly from the power adapter
with the battery removed, then the power adapter is good. In this case
we can suspect that the battery is defective.
This fault usually means the hard disk has failed or the disk controller, in most cases it is the hard disk that has failed.
Check the BIOS settings and see if the hard disk is detected, if not it is probably a faulty hard disk.
When you boot up the computer does the hard disk LED light flash and can you hear the hard disk spin up. If the hard disk is making a clicking noise then it is definitely faulty.
To test the hard disk another way, remove the hard disk and connect it to an USB hard disk adapter and connect it to a working computer's USB port. If this computer cannot detect this as an external hard drive and you can't open the folders and files, this confirms it as faulty.
To get the computer operational again, you need a new hard drive, Install Windows on the new hard drive with the computer's device drivers and your programs.
The fans on this unit are thermostatically controlled and only turn on when the predefined processor temperature is reached, so upon turning the unit on It will spin up too full speed and then seem to shut down until it is needed.
If you are getting no beep tones and since you have already tested your memory, I am forced to assume that either your processor has retired or your cmos is wrong, Since you sound like you have already opened the unit then locate the clear cmos jumper/switch on the board and clear your cmos which will reset to defaults.....if you still have the same problem then I reccomend trying a different processor.
Dell inspiron has a lot of promlem most are power adapter related ,Check and see if the power port is loose if you have tec savie repair the port .If you dont know how to repair the port your local computer guy will fix it about $100 at most places
