Lenovo g650 DC Adapter

What is that? I am looking at the complete list of IBM ThinkCenters, Thinkpads, Lenovo Essential products and so on. The whole list as far as I can see and there is no G650. There is a G50, but that is the closest.

If you have a valid model number (1234-31U format), go to

http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-69603

and enter the model number. In the resulting page, they will have part numbers for the DC adapter.

G560?
You'll need an adaptor able to deliver 19V DC 4.74A (65W) The DC plug should be wired to have a positive pin-centre and the barrel is negative.
There are several generic replacements available through ebay.
I'm not sure Lenovo make a G650 but happy to be proved wrong :)

There are differing voltage, amperage, and plug sizes on various Lenovo adapters, so I always recommend the precise replacement part for safety and reliability. ... Thinkpads_User

As far a plug size goes it's a 12.2mm length barrel with an external diameter of 5.5mm and the internal pin socket diameter is 2.5mm :)
 
If it's a G560 ....

hi, now in the market there are a dc adapter called Universal adapter, you can use it, it has a switch where u can select the needed voltage.

to see what is ur needed voltage just turn your laptop upside down, and check the notes their .

cheers.

I'm sorry guys, i might not have worded the question properly...I was looking for instructions on how to take the laptop apart to replace the adapter...

OK - so it's the adaptor's socket on the motherboard that needs attention?
Can you double-check the Thinkpad model reference?

For that, you need the model number and then go to the link I gave you. Put in the model number and then in the resulting support page, there will be a link there for the hardware maintenance manual (usually under publications). The HMM will tell you how to take the laptop apart and how to remove all FRU's (field replaceable units). ....Thinkpads_User

the model was a lenovo g550...sorry i thought it was a 650...ill take a look at the link and try and find the manual...Thank you.

Those manuals didn't cover changing certain parts.  Is there anywhere else that documentation might be?

Thank you.
