Inspirion 1100 wont boot, power light on

Hi, first off this seems like a great site! I’m excited to fix my problem with everyone’s help. Here is my story:

I’ve got a Dell Inspiron 1100 which had some overheating issues and, just recently took an unfortunate fall off my coffee table and did a face plant (screen down) on the floor…after that it will not boot and the display will not show up either. The battery will charge and the power light will come on so i do not think it is a power problem. The fan also turns on for about 5-10 secs then stops. The power light remains on until i press the power key again.

Now, i’ve done some research on this site and some others and i was able to open up the laptop correctly following a guide and look at everything. Things look okay (nothing was cracked or anything obvious…) and i basically cleaned the inside using an air can and disconnected the keyboard, monitor, and processor and reconnected them all. The problem was the same.

I read on this site that the cpu might not be seated properly but i don’t know how to clean off the old heat shrink gel stuff and put the new stuff on or anything else i should check for. ram?

Am i on the right track?

any help or other ideas would be appreciated. thanks.

does it make any noises (beeps) when booted? it slikely something has fallen loose or broken from the fall. The usual culprits are RAM and CPU that isnt seated properly.

no beeps just the power light and fan for about 3-5 seconds

i cleaned out the heatsink very well (there was ALOT of dust in there in big clumps!)

took out the memory and put it back in

this laptop does not have a wireless card, so i didnt do anything with that.

i bought the thermal grease, but i couldn’t separate the cpu from the heatsink and was afraid to force it. i tried the rotate method.

i couldn’t figure out how to remove the video card…so any help there would be nice. it had a metal shield on top and that came off easily, the harddrive connected to the side and i was able to take that out too, but then what?

the cpu has a screw that is marked “lock” and “unlock” for left and right. im guessing you need to unlock it to remove, then re-insert it and put it back to lock?

i even opened up the lcd screen and saw that the video cable just goes into the back of the shielding on the screen, so i didnt mess with it. still no video.

any help?

no, i dont see any lights on the keyboard. i tried reseating the cpu and memory and still no work.

basically, when i press power, i get the power light on, fan on (for like 15 secs) then fan stops and power light remains on.

i tried stripping the laptop down to basic components, (saw it in another forum) motherboard, cpu, video card, thats it, and that forum said i should be able to get a simple video output with an external monitor, but i could not... any ideas?

thanks!
