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 6ya Technician can help you resolve that issue over the phone in a minute or two.

You may have a burnt board or the input pin is bad, try wiggling the pin while it is plugged in to see if you can at least get the fans to start you obviously have a short of power in the power button area. You may want to try replacing the power button board for your model this may offer you a solution. If you take it in they can test it with a meter to make sure that this is the problem before a board issue is determined. It is difficult to diagnose this kind of things without the machine in front of me. My advice is to take it in and have the power investigated. Just because the lighting on the battery is going and showing signs of life does not mean the power button is not bad or not getting the proper power to start the computer. It seems to me that the power button board is bad. Or the input cord pin may be shorted out and only supplying power to the mains but not the power button circuitry. Just a good guess!......John
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.
Try removing one of the two memory SODIMMS under the cover on the bottom of the unit. It sounds like you could have a bad memory problem that is keeping the machine from completing the POST (power on self test). I'd try one stick at a time and see if that helps.
Good luck, please rate this solution if you feel it has helped!!
Try connecting it to an external monitor.
When you do, as soon as you press the power button to turn on the laptop, close the laptop lid - as this forces the laptop to display on an external monitor.
If this works, then it means the laptop screen is bad.
If it doesn't, the most likely cause would be that the laptop video card went bad.
For a while, some older Dell laptops with high-end nVidia graphics cards tended to die suddenly.
try taking out the memory.you can have the instructions by going to this link---http://support.dell.com/support/edocs/systems/ins1150/sm/upgrades.htm#1105389.Incase that does not work than i would suggest to get the motherboard replaced.You can contact the tech support incase you have the warranties and get it replaced
