Diagram i have a thinkpad R51 series laptop. the problem i need a diagram to take apart the laptop so i can resolder the power cord connector

Hi you can go www.lenovo.com > select support > select think brand products > select your model and you can download all drivers for your thinkpad. thanks

I concur with what Diegotech stated.

To iterate further;

1) The DC Power Jack (DC IN), may have cracked solder joint/s on the motherboard connector, (Female), where the DC Power Jack plugs in.

Resolder

2) The DC Power Jack may be broken.
Center Pin mount, and/or body of DC Power Jack, and/or Outer Shell mount.

Replace DC Power Jack.

3) Wires from the DC Power jack plug to the female connector on the motherboard, may be bad.

Replace DC Power Jack.

Two examples, of a place to buy an IBM ThinkPad T41 DC Power Jack,

2) http://www.machinaelectronics.com/store/buypart/IBM_Thinkpad_T41/DC-P001

Past this point it's a bad DC sensor on the motherboard.

Replace motherboard.

if your gonna replace your hard drive anyway,just take the old one out and tap it forcefully,better still take it apart and clean it of dust etc and gently micro-lubricate its moving parts see if you can get it working again--replace with same spec model--consult manufacturers site/manual for correct item.--good luck!

you may need to resolder the chipset at service. or just reinstall the driver if works in "safe mode".

have you tried dong an OS re-install with another hard drive? this is one way to verify if the USB port is really bad...you need to isolate the software-caused and hardware-caused problems.

The power on password is stored on an EEPROM chip. There are no backdoor passwords. There is a hack but you need to have some electronic skills and you need to pull the laptop apart.

check the battery is this new? if this is new then this is under warranty. if this is old you may check the connectivity. most batteries have an age life of 2 years. you need to replace this if you think this is already attained the 2 years long service
