RE: How do I replace the LCD screen hinge on my IBM T41

(posted by dgm9 on Nov 15, 2007 - http://www.fixya.com/support/t258222-replace_lcd_screen_hinge_ibm_t41)

I have just read your excellent description of the hinge replacement and I have the exact same problem, except that it is the left hinge on a T40 and am considering a DIY. After looking at my T40, before investing in parts, I am wondering if the replacement steps for the Top cover assembly are the same on the T40 and also if any removal of the Bottom keyboard area is required. I ask only because I am seeing a white wire exposed next to left hinge after it separated from the Top cover.

I have found replacement hinges (part # 91P8388 available at IBM/Lenovo for $27.50, Thinkpad-Parts for $20.00 (used) and eBay for $15-$30.

Thanks in advance for your help ...

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.

My IBM Thinkpad T41 LCD screen blank when power is ON.Please assist me.This happen because I did not use my laptop for about 6 months.


Hi, This issue is clearly hardware and might be related to 3 part, Inverter card, LCD cable or LCD Panel ( Or systemboard, just to make sure try with an external display if the issue reproduce it's systemboard/graphic card related, if not LCD related ). If you are still entitled to warranty then this hardware failure is covered by the terms. You should have the 3 parts stated below replaced as it s a common issue with Thinkpads.
In case you are out of warranty cover you still can try to subscribe to a warranty extension, you can check on www.lenovo.com , otherwise you might want to order theses parts on a website such as ebay. To swap the pieces requires quiet advanced skills as you have to take down the whole computer, obviously LCD Panel included. Unfortunalty this is hardware related, not much you can do... I hope this help ! Thanks and have a nice day ! J -

It wont turn on, and when it turns on, the slightest movement of the laptop will make the screen black and sometimes, the screen has a glitch, i can't move my pointer anywhere and it just hangs. Please I...


Most likely its the LCD cable from motherboard to the screen. This can get damaged especially in the hinge area and can prevent the laptop from turning on and the other problems you mention. Replacing the LCD cable should solve all your problems.

How do I replace the LCD screen hinge on my IBM T41?


I'm sure you could get these hinges from IBM, but no idea as to their cost. They are available on e-bay for $8-$35 (depending on whether you want 1 or a set) plus $8-$10 shipping.

As far as replacement. You will have to remove the Top cover assembly from the base of the PC. If you need help with that, just let me know and I'll talk you through that.

To replace the hinge, you will have to disassemble the Top cover assembly.The screws that you will need to remove are covered by small black adhesive covers. There are 3 round ones along the bottom of the bezel, 2 square ones up at the top of the bezel (to the left of the white LED keyboard light, and 6 (trapezoidal shaped) on the outside of the cover (3 on each side). Carefully remove those covers and the screws that are under the covers. Keep track of where the screws should go back in.

The actual bezel is held into the top cover with some internal snaps. Start at one of the corners, run a knife blade along the seam (between the cover and bezel) and you will hear each fastener "snap" as you slide the blade past it. Once the bezel is loose, lift it off of the LDC screen. There is one additional screw that is located up in the upper right hand corner. That one will need to be removed, also.

Gently lift the right hand side of the LCD assembly a couple of inches and place something of appropriate size to hold it in the raised position. You will see 2 additional screws that hold the hinge to the LCD assemble. Remove those and the old hinge will come right off.

Position the new hinge and replace the two screws that you had just removed. Reverse the removal sequence to reassemble the display.

Before you start snapping the bezel back into place, check to make sure that the two cover catches (those hook things, up at the top of the LCD assembly) are both operational. The link going to the left hand one tends to easily fall off.

This procedure should take in the neighborhood of 45 minutes to an hour.

If you need any additional information, please feel free to ask. If this information has assisted you in the resolution of you problem, please return here to give my assistance an appropriate final rating. If this information has answered your question and/or lead to a resolution, please rate it as "Fixya!".
Thanks you, and have a super day!
