Lenovo G770 Assembly/Rebuild

2013-05-11, 18:17 PM

Re: G770-1037


I am going to mention a few notes for anyone else who is thinking about servicing an out-of-warranty system, I am not A+ certified however I am an engineer and I have worked in several Tech/ID positions. I have repaired many laptops and I have never left one worse than it was when I got it. I appreciate that this manual is available, but there is some important information missing.


To remove the keyboard, there are some little metal springs along the top and sides of the keyboard that need to be pressed away from the keyboard before lifting the top of it. (after removing the three back screws) I also ended up putting a folded piece of paper towel over the keyboard connector to help hold it in place (the black piece of this poorly designed connector folds up and does not stay down)


Most of the screws are 2.5x8mm and black in color, there are 4 flat smaller-dia ones above the battery and 2 even smaller ones above the DVD/BR. HDD, internal screen hinges, and maybe a few others are silver/metal in color. I have two short black ones which I do not remember removing... kudoes to anyone who can figure out where they came from.

I know that the thread-locker is not 100% effective, and I don't mind tightening the screws on a device occasionally. However this is the first laptop (or general device) that simply fell apart on me so quickly, the left hinge is a clearly better design with a metal bracket on the "keyboard bezel" than the one the right which is just a small nut in a platic support. The others appear to be ok but this one supports the Screen's Hinge so it's dealing with a lot more weight and a moving part. (the hinges seem to be good and strong)


I originally disassembled the machine for two separate issues, one was the right-hinge (for which the screw had worked it's way loose/out) and the other was intermittent screen issues. Both were observed well before my one year manufacturer's warranty ran out but the IDEA service center is a pain to work with. I am usually frusterated enough after dealing with the automated brittish voice and having an indian lie to me about his name.


Rant: I have an indian girl-friend and I am not prejudice, but whoever is running that department is just rude and ignorant if they think I'd rather be lied to by my rep/operator. If we are going to give them alternate names so that I can pronounce them that's fine but making it something believable would be less insulting to me. I spoke with a ThinkPad person who was very helpful. The IDEA support staff can't/won't even send me a few spare screws, which has never been an issue for any other company in my experience. Half the time they seem to ignore what I am asking for and respond with a random useless answer.


Anyways the warranty finally lapsed so I didn't feel as bad about fixing it myself, by this point all the plastic was beaten up under the right hinge but I am pretty proud of how well I was able to put it back together with super-glue. I then reinforced the supports with JB-weld so hopefully that won't happen again. I was not able to observe any damage to the cables or video connections, the video issue is intermittent and I have not been able to consistently reproduce it thus far but I will follow up.


Otherwise I think this is a good laptop reasonably priced with plenty of nice features, I just wish the lenovo support staff was not so useless. They really just can't or don't seem to want to help at all, so I don't get the point of having them there.
