Pdf Laptop Motherboard Diagram

[Magin Sriubas]

Hiwill the motherboard schematics be published shortly?

The only competitor to the Framework laptop that I know of, which is called the MNT Reform, has already published their schematics here: _static/schem/reform2-motherboardx.pdf

If nothing else, the schematics would be educational.

Currently the full schematic set is only available to repair shops (including independent repair shops) who get in Framework hardware. We like to share as much as we can, but we are currently not able to share that information publicly or to individuals.

That kind of laptop mods have also been done with Dell Inspiron 11 models which were sold with eMMC or SATA storage yet used the same motherboard, if I recall someone did a similar mod of re-adding the SATA connector which required a few small changes of resistors.

The only hardware risk is the BIOS may still default to eMMC boot.

Thanks @jayeff, your help much appreciated. I've checked both links for schematics and both are not correct system. What I really need is to identify the chip that got fried. which looks like its marked on the board as "C2503" next to the white battery connector. Unfortunately as it is fried its id number is partly invisible. Any ideas how to identify which chip it is? On a second thought I'm not sure the schematics would help, maybe a boardview? Any ideas how to find the chip number?

The number that you have been given is the HP part number for the motherboard, not the board number and searching online using this part number or the laptop model number gives no results for the schematics.

Here's the maintenance and service guide for the laptop, taken from this webpage. Go to p.36 to view the necessary pre-requiste steps and then the procedure to remove/replace the systemboard. You don't have to remove it but this should be helpful in gaining access to it to find the board number. Apologies if you know how to do this already

A C identification on a circuit board means that it is a capacitor. If it is fried I daresay that an IC component (Q designation - transistor or D designation - diode) nearby might also be faulty as well. Usually capacitors only have 3 digits if they're a smd type component. Post a close up image of just that section of the board.

The schematics would help as they would show what the component connects to which would help in knowing what it did and you could test the components further on in the output circuit path of the transistor to see if they're OK or not.

Components burning out are due to excess current flow, so either the component itself failed which can happen or other components have failed and this altered the circuit characteristics or there is another introduced problem such as water entering or someone checking with the power still connected and not being careful and creating circuit paths that weren't meant to be there in the first place.

Wow, amazing @jayeff, good to know i'm not the only one changing battery and burning a board on a clients dining table :) After reading all the occurences of Apache2223 in Digi-key forum I feel it would be wiser not spend more time and I'll order a replacement board. The only question left unanswered is what caused the chip to burn and is it related to that replacement battery that might burn another board? what do you reckon?

It may depend on whether the component is downstream from the battery or upstream i.e. is its output feeding into the battery so that if there was a problem in the battery this may cause it to burn out or was it on the motherboard so that battery wasn't the culprit.

Replace the component on the board (didn't check as to the cost so don't know if this is worthwhile or not) and insert the old battery if you still have it and check what happens. If OK as far as the component goes, then install the replacement battery and check

Video cable. A video signal from the motherboard goes to the LCD screen through the video cable. The video cable connects to the motherboard (or video card) through the connector 1. The video cable connects to the LCD screen through the connector 2. The video cable (in most cases) is also responsible for supplying a necessary voltage for the FL inverter board. The video cable connects to the FL inverter board at the point 3.

FL inverter board. This board is responsible for converting low voltage DC power (point 3) to high voltage AC (point 4), necessary to light up the backlight bulb. If the FL inverter board is bad, the LCD screen (backlight bulb) will not light up when you turn on the laptop, but you still should be able to see a very dim image on the screen.

Last week, my IBM T30 LCD screen needed a wiggle to display an image. This week, display is completely gone. the LCD is always lit but no image. All connectors on your diagram (1-4) has been reseated but no improvement. Any idea? Thanks.

Men! thanks for such a powerful website. i got a dell inspiron 9300 with dispay problems, there are some vertical lines of varring coluors on the screen the problem has been on for about a month now it the lines are increasing periodically, also now the screen size has reduced from the original 17inches to about 15 inches how can i fix it?

ok i have a dell inspiron1150 i read the artical of fixing the dim screen ok when i first turn the computer on i see the dell name for a sec then its all dim i looked for swicth no luck in fiding one but i see talked about magnet which i did find whats the magnet pull a switch from insode the computer or is there something else wrong with it . it did it before but i left it alone foe few days then it worked but the time its staying dim .need some help dont really want to get a new one

I have a dell inspiron 6000. I turned the laptop on this morning and straight away there was a single vertical yellow line about 3 pixels thick right down the middle of the screen. This line is present through all the programs and ive tried rebooting the computer.

I have a toshiba satalite p35-605 17 in laptop and i bought a cable to connect to the tv. I have tried to get it to display on the tv for hours, but its not working. I used the fn f5 key and altered settings in the properties but nothing seems to work. the tv screen will flicker, but doesnt do anything else. if anyone knows what might be the problem let me know. I have tested the cord with other computers and it works fine. thanks

i need help on how 2 fix the dell latitude cpi when i try n switch it on nothin happens and the batty wont charge and when i plug the charger in nothing happens can you help me plz email me back on how 2 fix this problem and what i can do? txt back mark

I bought a replacement lcd online for 230.00 and did it myself. Shop around a bit and you can find a lcd at a decent price and do it yourself. This isnt hard, just take your time and have a small screwdriver!

I m having a problem with my lcd it boots fine but here is a dark screen on my ibm p3 it works fine with an external monitor but it can not play the vedio files (songs) while i plug into the external monitor .Here is a white line also on the laptop screen in the left side of it.I can feel a dim light in it but no any display what kind of problem is it can i sort it out my self,plz reply immiediate.

thank u

I have a Toshiba Satellite P35-S611 laptop, which is 1.5 years old. Recently, I noticed a vertical purple line that comes up every so often. Does it mean that my LCD monitor is gonna die? What needs to be replaced?

I have been checking a Presario X1000 notebook. It was working, hang up, mu client restarted it and it never came on again. No video, no sound. The first thing I noticed was that the cpu fan sopped spinning 3 seconds after I turned the notebook on. It has the video card on another board, I pushed the card by the superior part, near wher the screen connector is, and the notebook started normally, I reainstalled Windows XP and I installed Max OS X for intel on it. But if you merely hit the notebook or put it too strong on the table, the same problem again, I was as at the beginning. I have cleaned the video card contacts with contact cleaner and nothing. The video card has two sockets to the right side of it, I cleaned the connector sockets and nothing. Any idea?

I have an old compaq armada 7800. Recently the screen goes all discoloured(reminds me of a mood ring) and the screen goes white. If i squeeze the sides sometimes the image will come back or sometimes freeze. Should I take it apart ? Is there a way to tighten the frame because it seems like the squeezing of it sometimes helps

Hi, Laptop Repair Guy: I have a Toshiba model 1955 laptop. In trying to correct an overheating problem, I disassembled most of the computer before cleaning the air blower chamber, because I had trouble with the cover screws, and thought I could take the whole bottom pan off. Had I read your site first, I would not have made the mistake.

After I assembled the computer, the overheating problem is solved, but the screen does not light up, even though it was working fine before the repair. I presume there is a faulty connection somewhere that sends power to the screen even though I the only cable I disconnected was the one to the hard drive, but the system seems to be powering up fine. Can you give me some idea of where to look for the problem, or how to test to verify if the connections to the screen are feeding signal and power to the screen?..

Thanks for your help. Tom Erickson..
