Greetings to all members.
I need help with the repair of the Lenovo IdeaCentre A700-24ISH.
I found this computer in a junkyard, physically in excellent condition, but of course it doesn't work at all.
The power supply is ok, but when i press the power button, nothing happens, not even one LED that doesn't light up.
What I noticed is that the computer was already somewhere in the service because i see that the BIOS chips were all freshly soldered, so their functionality is questionable.
If anyone has a schematic and dump files for this computer I would greatly appreciate it.
What I managed to check is the following;
There are no short circuits on any part of the board, caps, mosfets etc... Voltages that are constantly present: 5v on all USB ports, 3.3v on the power button (when pressed it drops to 0v and that's ok), 3.3v on pin 8 of the two BIOS chips. One with the position U301 MX25L8006E (it is connected to the SuperIO IC IT8783 which also receives 3.3v power on its VCC pins and on pin 85 RSMRST has a constant 2.7V connected to the PCH bridge), one with the position U4701 MX25L6406E (it is connected to the PCH bridge IC that has 1.0V on VCORE.
There is no voltage on CPU or GPU VCORE.
There are two more BIOS chips with the position U5002 WB25X20CL and U3402 MX25L1673E which have no voltage on the VCC pins and I don't know what function they would have since I can't find a schematic anywhere...
I have read all the dump files of those chips that are attached.
I would just like to try to program all those eeproms with the correct files so that I can know if the problem is in the SuperIO or the PHC IC, so if anyone can help I would be very grateful.

Thank you, but unfortunately this dump didn't work either, except that now I have a short pulse of 300mV every three to four seconds on the RAM power supply part as if it is trying to start.

Try looking hardware issues.

I did, but since I can't find the schematic anywhere, it's not worth investing more time. Thanks anyway.🍻
