Hi,

The weirdest thing just happened. I have a Toshiba Satellite Laptop (A105-S4334) and I noticed that it was getting very hot and then it would just shutdown. I noticed that the fan was no longer running and hence the laptop probably was overheating and shutdown. So after doing some research online all the information I found was pointing to the fact that there was probably some dust stuck in the fan and vent. So I opened up the laptop (following directions) and cleaned out the fan. However, when I was opening the laptop, I accidentally pulled too hard on the keyboard connector and the latch came out. So basically I can't connect the keyboard anymore. So anyways I put everything back together (except the keyboard) and closed it up. I put the battery back in and when I went to power up the laptop, nothing happened. It just went dead. There is power going to the laptop through the battery, but it just won't power up. Does anyone know what could have happened? Do all the connectors have to be in place before it can come on again? I am completely lost.

I would appreciate any advice.

Thanks much.

If the laptop wont power on you missed a connection somewhere or you fried a component with ESD (electro static discharge *spelling*) As for the keyboard where did the cable pull out from the motherboard or the keyboard?

not sure what all you may have not connected or broke ,but the keyboard ribbon cable should still go back in to the slot even if you broke of the locking tabs like this in the link .
but that laptop should boot with out the keyboard plugged in i think

@Sneakycyber,

The keyboard connector came out just like caperjac mentioned in the link. So I guess the only way to put it back is tape it?

So how would I know or what can I do it ESD was the cause? What are my options?

Thanks for your reply.

@caperjac,

THanks for the link. That is exactly my problem except both tabs broke (in the picture it shows 1 broken). Then I guess taping is the only solution? Can you buy those connectors anywhere?

Thanks.

not really sure where you could buy one ,i have actually broke a couple of them in my early days of messing with laptops and broke both tabs off one just like you and use a small dab of hot glue on bot side of it [ the electric gun type ] to hold it in ,customer is still using that laptop

These connectors are called Zero Insertion Force (ZIF) connectors.

They are easy to find and purchase at well stocked electronics parts and supply stores. However, they are one pain in the neck to solder to the motherboard!

Not to go off your topic or concerns, I have been pain-stakingly been trying to replace a 60 conductor )ZIF connector on a Sony Play Station 3 motherboard for the Blue-Ray player, the locking clip was broken off.

So believe me when I say those connectors are hard to replace with-out the use of a microscope and soldering tools with ultra-fine soldering tips to avoid possible solder bridges. (Solder bridges are caused by molten solder spilling over onto adjacent connectors.

If you wanted to find such connectors, you can check out http://www.digikey.com and look for ZIF type connectors with the same number of connectors as the one you broke the flip lock off of.

It is my suggestion however, that you have the connector replaced professionally.

Bruce.

If you damaged a component from static electricity the only way to find out is to get the motherboard to POST (Power On Self Test). If you cant get the board to POST then its likely a problem with the motherboard or as I said earlier you missed a connection somewhere. It could also be a problem with your battery or your power adapter make sure both are working correctly, if the battery is damaged removing it from the laptop should allow it to run off the AC adapter.
