First, I was given this notebook in this condition. There is no visible damage, every thing appears to be in great condition, no signs of abbuse in any way, shape or form. Second, model is an exact match Q551L, but notebook is 17" screen, 1tb H.D. and 4g Ram. Ok…. Every time the lid is opened it crashes. No matter what I try. If the lid is left down the unit functions great. Connect a monitor, keyboard, mouse and all is good. Raise the lid to the point of switching to on board screen and CRASH, everything is gone! Try powering on with the lid open? Starts booting just to the point of graphics appear on the screen and it crashes. Upon inspection of hardware, all seems good. Almost seems as if the amount of power required to light the screen is overloading something. Also in order to boot it up again, I must first pull not only the main battery but the bios battery as well, Reconnect batteries and A/C adapter and it boots right up. Again open the lid just a tiny bit, slowly….keys backlight …..ok …little more……screen lights up and CRASH !! Lights out !!!! All is gone. Sorry for the lengthy question, any ideas or a response at all would be greatly appreciated. Thank you for your time, and have a beautiful day. Update (07/10/2018) Here are some pics of the notebook.
Hi @codemanlivs , Can you try disconnecting the LVDS cable on the motherboard and using an external monitor then start the laptop with the lid up? I think the LVDS cable also contains the backlight power as I can’t find a separate cable in the parts list BUT I may be wrong about this. If it starts OK without crashing it may be that the backlighting has a problem and is overloading the supply causing the protection circuits to come into play. If it still occurs with the LVDS cable disconnected from the motherboard, disconnect all the cables coming from the lid to the motherboard (on the motherboard) and try again, just in case the backlighting is on a separate cable Ensure the power is totally disconnected from the laptop including the battery, before disconnecting the cable(s) If it works OK then it points to the problem in the screen
