Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

Please help, i need schematic diagram for Dell inspiron 3537 board LA-9982P rev 3.0 (A02). Specific for A02.
I have a one beep with no display problem. Did reprogrammed the bios but no luck. i tried to troubleshoot using rev 3.0 (A08) version schematic and boardview but there's components/rails in the schematic that is none in my actual board, this is why I'm having problem checking every power rail needed if ok. attached is the photo of my actual board.
I'm not sure if A02 and A08 is really different schematic version from each other, but I have to try.... -

Main board CG410/CG510 NM-A681 rev 1.0
I have this Lenovo laptop under repair with strange behavior, no display at first I thought it has a corrupt bios but now after disassembling it I have doubts, the laptop turns on automatically after inserting the charger without pressing the power button, If I hold down the power button for 8 seconds, it turns off for 1 second but turns on immediately after 1 second, so you can't even turn it off, tested with and without RAM,... -

Hi good Friends., today working on a Macbook Pro A2289, Logic board 820-01978-A. The history was liquid spill, Cleaned & replaced all corroded components & now the logic board shows 20v & .01amp on the meter. Not taking in any amps. Upon trouble shooting I get the required stable voltages 5V, PP3V3_G3H 3.3V but no PP3V3_S5. Checked the schematic, assume that this is generated from U7800. Checked all the Input/Output voltages on this chip. All is fine, except PP3V3_S5 is missing. Resistance from GND to PP3V3_S5 is 146 Kohms. First I need to make sure whether PP3V3_S5 is generated from...
