Why won't my laptop monitor turn on?

Question

Do it yourself

Notebook Asus K73E. After disassembling and cleaning it, the monitor does not turn on and the hard drive indicator does not light up. What could be the reasons? How to fix? What to do?

Answer 1

If there are no extra bolts left during assembly, then it was not assembled correctly. At each bulkhead, I have 2-3 extra bolts left and everything works fine =)))

Answer 2

Take it to the service.

Answer 3

take apart and reassemble. I think it should help, the main thing is to make sure that all loops are connected

Answer 4

Well, for my 3 years of experience, there were 3 main options:
1) they forgot to remove / removed the battery at the wrong time and or burned some kind of mikruha (then it’s really a pity), caused the microcircuit to block the breakdown, etc. then it helps either to pull out the battery and the power supply for 5-30 minutes (it depends on the conders inside) or to find how to reset the BIOS if the power circuit has already been restored (yes, it really helps in 1 out of 30 cases and yes, this may be a problem)
2) cable - then we wipe the flat ones (from greasy fingers) with an eraser, if we poke the terminal blocks, we look so that they sit tightly, and during the collection the cables do not twitch.
3) during the cleaning of the cooler, you scored it. And I met one like that at all, I don’t remember the model anymore, the mikruha in it blocked the loading of everything except the power supply (the diodes are on and that’s it), they replaced it and everything worked after resetting the BIOS.

Answer 5

Move the memory module from slot to slot. If the cooling system was removed, the matrix connector may have been disconnected. If you forgot to remove the battery, then there may be a couple more options.

Answer 6

If possible, then try to turn it on without a screw with an external monitor connected to the laptop and describe here what happened in the end.
