Hello!

 

My Toshiba Satellite P755-S5265 has not been able to turn on at all. That's because the AC adapter would not be charging the battery nor would it operate the computer.

 

Whenever I would plug in my adapter, a weird clicking noise would come out from the computer. Also, the AC adapter charging light would blink continuously as well. I

 

took apart my laptop and discovered that the end my of DC power jack was the source of the clicking. When I mean the end, I don't mean the area where I plug in my adapter, it's the other end that's connected to the motherboard.

 

Does anybody have any advice on what I should do? Is my laptop dead and done for?

 

Thank you so much in advance!

These things have a safety measure that prevents too much power from entering the system so it is far too early to call it dead. 

 

Can you check if some of the caps are busted? (they look like this) 5171910775_f6a24af468_z.jpg

 

Another issue that might affect this is a poorly solder IC somewhere.

 

Unless you are a pro when it comes to electronics, i would suggest you to let the specialist to look at this.

Thanks for replying so fast!

I don't see any busted caps.

 

I've had this laptop for a little less than 2 years and there were problems the moment I opened it fresh from the box. I used the Toshiba warranty to get the laptop fixed, but there would constantly be problems that would prevent the computer from operating. As a result, I've sent the laptop back to Toshiba many times. Maybe this laptop was just badly put together?

Any other ideas on what I can do aside from sending it to a specialist?

I'm sorry but when it comes to electricity, I would rather leave it to a specialist.

 

But if you are confident with your electronic skillz :

 

You could try checking the voltages on the connection to check if it is receiving a sufficient amount of power or if it is properly connected. That clicking sound might mean a poorly soldered part somewhere.

 

Once you isolated the issue, you can try to fix the connection or replace that broken part. 

 

You can also let someone lend you a compatible charger and see if it might have been the cause of problems.

 

Sorry I can't help you that much. If I was your neighbor I would've fix it myself. :(
