Hello friends,
MSI MS-16S6 (MS-16S61 VER:1.1) I need schematic

[tarum2003]

the two resistors in the picture are broken. What are the resistance values?

Take a clear photo of the board section with the code of your board and I will tell you the resistance of the missing resistors

Thank you for your reply. I've included closer photos.

You didn't understand me. I'm interested in the area with the barcode highlighted in red, the label indicates the code for your motherboard 16S61/xxS

Hi Rezistor, it looks like you have access to schematics for this series. Would you happen to have the schematic for MS-16S61 36S that you could share? I have a boardview but really need the schematic.

I'm trying to troubleshoot my grandson's dead Prestige 15 laptop. It's negotiating a 20V PD power rail which I see at the input mosfets, and consumes a steady 20ma which leads me to believe at least the LDO standby is alive. It looks like the main board voltage is 12V, at least that's the +VBATA at the battery connector and +VIN at the TPS51285B LDO regulator (PU21). But the LDO regulator isn't working, I'm getting 0V on the VREG3 (+3VALW) output and 2.6V on the VREG5 (+5VALW) output. The +3V and +5V switch outputs are 0V as well. I'm also getting 2ohms to ground on the VREG3 pin which isn't a dead short but pretty low, and likely explains why the output is pulled low. This low resistance exists when the LDO is removed as well, so it's not the LDO itself that's partial shorted. I'd expect 2ohm resistance on the CPU power rail but not at the +3VALW? +5VALW resistance is ~35Kohms, which seems okay. The TPS51285B datasheets says that VREG5 turns on when VREG3 reaches 2.4V. Since VREG3 is 0V, I'd have expected VREG5 to be 0V as well, not turn half way on, but maybe that's normal.

I've changed the LDO regulator already, cleaned the pads, reflowed, etc. and can't get it to work. It's also missing capacitor PC217 on the VREG3 output (I originally removed and then lost it) but a missing decoupling capacitor shouldn't be causing this issue. I'd still like to replace it, I expect it's a 10uf or 22uf. The schematic would be helpful for this too.

The boardview has been helpful in connecting things, but without part numbers, values, or voltage rail references I'm flying a bit blind here. Having a schematic would sure help nail down some of these questions I have.

Thanks in advance!
