Take the battery out and disconnect the power supply. Let the laptop sit for a few minutes. Connect just the power supply, wait a moment, and try turning the laptop on. If the laptop does not start, disconnect the power supply, wait a few minutes, connect the battery, and try starting it again. Let us know if the laptop starts up under either of these conditions.

i tried your suggestion and nothing seems to work.

Pull everything that you can pull-- optical drive, RAM, MiniPCI cards, hard drive, any PCMCIA cards. See what happens then.

If you've got nothing, then, you're probably looking at either a bad motherboard or a bad processor. If you're out of warranty, then that stinks-- you'd want to contact Dell and purchase some replacement parts to fix your unit.

Thanks for the help

Glad to help-- be sure to let us know how everything goes!

Hi There, mine laptop was unable to use power on when using power adapter, but the battery did start. However, when power adapter is plug in, the power LED & the Battery Led is blinking non-stop & can't be switch on. Worse is that my battery can't be charge too.....any solution guys??

YES any solution on this subject...I have same issues with blinking lights. I just took the whole computer apart piece by piece put back together and so far it seems to be charging the battery (no flashing leds after 30 min so far...this is good...I will repost something if it actually charges battery and runs under battery power. I always kept battery in while mostly having laptop plugged in when I did use it. I rarely used this laptop to begin with...Didn't know I could or should remove battery while plugged in. I thought once plugged in the adapter superceeds the battery?

Thanks

I have been reading through the many postings from folks having issues with the Dell Inspiron 1150. I am working on an 1150 that was dropped while connected to the AC power adapter. Of course this broke the connector off the motherboard. The 1150 still worked with the battery until it died. I ordered a replacement power connector and soldered it on the other day. When I connected the laptop up to AC power the front power indicator came on and only the fan started, nothing else happens, no screen, no POST, no beeps, no BIOS, nothing. I reseated the RAM, no good, so I removed the battery and tried with just the AC power, same results. I then went to the Dell support site and dug around there and ran their support wizard and it is telling me the "reed switch" has failed. From what I can tell this is part of the LCD display assembly. I am confused as to why this would have failed since I completely disassembled the laptop and the LCD display unit was not attached . All I worked on was the system board and then only in the area where the AC power adapter goes. I was careful not to hold the soldering iron on to long so as not to heat up any surrounding parts.
Anyone else have this issue? Or find out why their 1150s won't power up, just getting the power indicator on the front edge?

Thanks

My inspiron 630m had a similar problem. I works fine if the battery is removed from the system, but if the battery is connected, orange light blinks and cannot be turned on(even with AC). The battery looks fine with 3 LEDs on when checked for charge.
Can anyone please help me?
