    I don't think the absence of the ceramic capacitor would cause this issue.
    However PU1102/PU1103 should not turn on when charging the battery only (computer off). If PU1103 did blow up when the computer was off, most likely you got a short somewhere around PU1102 (either it was bad or you didn't solder it back correctly).

            so now after replacing all off those bad things the laptop turn on now but with a dead screen.. when i press the power button the keyboard backlight is on and the fan spin for a while and stop and it shows nothing on the screen. i already double checked the display connection to the board, and everything seems to be ok. what do i need to do now ?

                Lenovo Thinkpad T14s completely dead.
                by Andreasbest
                Hello.
                I received a T14s Gen1 ( NM-C891 motherboard ) that is completely dead, no indication of life at all.
                I tried hard reset without RTC battery and short both pins of it for 1 minute but no luck.
                Since it's type C connector i have no idea what to measure or where to inject voltage, so any advice are welcomed
                Thank you in advance!

                Lenovo T14 Gen 2 Type 20XK Model 20XK0069US Odd Charging Issues
                by coasterghost
                For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

                Lenovo T490s completely dead
                by Andreasbest
                Hello!
                I received a fantastic T490s that is completely dead, after i removed the back cover i noticed a totally fried cap (attachement) pic, i remove it and cleaned the pcb, seems undamaged, although the nearby caps are shorted, PU1001 looks physically undamaged.
                Any advice please?
                Thank you in advance!

                Lenovo ThinkPad E14 Gen 5 - Not Powering On - 3 Blinking Lights - 20 volts 0.224 amps
                by bialag
                Hello,

                I have a Lenovo here that does not want to power on. The motherboard appears to be clean, no sign of corrosion or obvious fried components. When plugged in, I see 3 blinking lights and then off. It would cycle the 3 blinking lights every 10 seconds or so as long as I have the adapter plugged in. Amp meter shows 20 volts, 0.224 amps, no fan spin, red light indicator near the charge port.

                Thermal camera shows a section of the motherboard that is warmer than the rest. It is near the connector labels JRTC1 (CMOS battery). Diode measurement to ground for pin 1 = OL,...

                by max-power
                Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
                that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.

                After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place...
