Yellow wire on m5500 motherboard

Alienware m5500i-R3 laptop.

Recently, the video card in it died. So, I order a new one, put it in, and it worked. There were lines going across the screen, however. I pulled the card out and reseated, and that's where the trouble started.

After reseating the card, the laptop would not boot. It would start up for about 2-3 seconds, but before POST, it would restart. No beeps or anything. Checked the video card, RAM, CPu, battery. Reset CMOS. Checked all the cables. Nothing.

Then I noticed that there's a very tiny wire running from beside the RAM to underneath the black masking beneath the video card. It's covered by the black-cloth-tape stuff. It seems while reseating the video card the second time, I managed to disconnect the wire. It looks like it was soldered to a contact on the board, but I can't tell which one.

I'm assuming that this is why the laptop's not booting. Does anybody happen to know which contact it connects to, or have a reference picture I can use?

 

Have you tried Alienware website support and go to FAQ\knowlage base and type in m5500 look for add and remove ram. It should give you a picture of your bottem of your laptop.

I think it your wireless card for wireless internet

edit that there drawing suck lol use How do I reseat or replace the video module on an Alienware Area-51 m5500?

 

Thanks, but that one is different than mine. I wish I had a picture

It's not a wireless cable. It just seems to be connecting one contact point on the mobo to another contact point, so I'm assuming it's transferring power for something.

 

Can you give me your Specs

I think you have the m5550i-R3 Note the extra 5

 

You're right. The back of the laptop says m5500i-r3, but upon inspecting my purchase invoice, it's really an m5550i-r3.

 

is the Wire by the Cmos battery. I beleave the Wireless n/b card is there and it attached to a wire for antana.

 

The lose wire plug into something like this

I took some pictures. It's a very tiny wire. I don't think there will be guides for this one anywhere lol.

 

That one I am unsure of. It looks like it gose under the Ram chips Near the North Brige chip.

 

Hi. Have got my 5500 apart to replace the Video card - has a similiar wire.
At the end that is loose, is soldered to the leg of a surface mount transister, which is insulated from board with bit of tape. It is going to take a very steady hand, very fine tipped iron and magnifying glass, to re-solder it.
Just to be sure that your wire and mine are doing the same thing, the second photo is of the other end, socket is for the fan. It would probably be advisable to know if the motherboards are exactly the same version/revision/mods. But I haven't been able to get the notebook apart to find any mod tags. The board label is 37GP5300-C0 PCB M/B BD P53 REV:C.
Hope the photo is of use, Good Luck.
