    Hp Omni 200-5340LA with weird symptom (possible cap)

    Hello and good morning from my end. To keep this nice and short, there are 2 capacitors in the power area of the CPU that show damage that i'm having trouble identifying with markings
    330
    EFK
    L60

    More or less is that is anywhere from 220uf and up to but not 470uf with a no idea in voltage, give or take 20v, 25v, or 30v as the max power is 19v at 7.89A.

    What the computer does is, the LEDs blink rapidly until it is unplugged from the power supply. If the CPU is removed from the socket then reinserted, it turns on as if nothing happen. After a restart or give or take 30 minutes of inactive use, the problem shows up again. What i've done so far to figure out its an issue on the motherboard is remove the ram, any peripherals, change the CPU, and run tests with a Live CD that checks all the hardware (Geek Squad uses this as well to diagnose computers hehehe) and they all pass as ok. Hopefully with changing these caps the problem is resolved. Thanks for any and all help/ guidance in advance.

      @diff Thank you very much for the Info! With this info it will make it easier on getting the voltage. By any chance do you know what the L60 part might mean?

        Probably the date or lot code.

          ok thanks.

          I went out to look for a replacement cap and i was given these (Picture included). Now the computer briefly turns the led on and then turns off. I'm thinking the cap is not the right one or there's a short somewhere. Also, added electrical tap to prevent the metal casing from making contact with the caps.

              From the appearance I can not recognize any quality brand. Most likely something liek Jamicon or similar crap. Is that even low-ESR at least?

                i think jamicon are better printed than that.
                probably SunTan or something else you can get retail.

                  Screen dimmer in recent months, weird symptom: EPG screen goes bright! LG 19LD350
                  by Hairspring
                  In recent months the screen has been getting more and more dim. If that was all, I'd suppose the problem would be the backlight (LED? LCD?). But I've noticed this really weird symptom: switching to the EPG screen restores normal brightness! And then, even weirder, when I go back to the programme, for a moment the programme is at normal brightness and over the next 1-2 seconds it gradually dims down again.

                  Last time I looked in a TV it had EHT flyback, so I'm no expert. I do sometimes repair computer monitors and power supplies, most often when there's bad caps.

                  Anyhow,...

                  (Weird) BIOS info for HP Pavilion Aero 13-be1021AU
                  by Loki_Fido
                  Hi folks,

                  This HP Pavilion Aero 13-be1021AU came to me for a repair. And it seems to have a weird BIOS chip. (Pic attached)
                  I asked my CH341A to read it and doesn't even know what to do with this. We are both very confused.

                  BIOS - XMC 25RU128CH10 (1.8v)

                  What the heck is this? I looked all over the MB. This is the only bios.
                  When I asked the NeoProgrammer to detect it, it just pops up an empty screen, and asked me to enter the bios number. And when I did, it doesn't do anything. NeoProgrammer showed me just this SPI ID: 204418. Don't know what...

                  APC BR1000G battery backup has a weird issue sometimes a bad battery icon and making a weird sound for about 30 seconds
                  by sam_sam_sam
                  This started a few days ago and does this about every 8 hours

                  After it does this it goes back to normal no bad battery icon and no weird sounds and it goes to battery backup mode so I am not sure what is going on with this battery backup

                  The battery backup is about 3 or 4 years old

                  Dose anyone have any idea on how to troubleshoot this issue I have never had a battery backup do this kind-a thing before so I am not sure exactly how to troubleshoot it and where to start

                  820-02020 Super Weird Issue: Keyboard Input Character Map "Wrong"?
                  by ugamazing
                  So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:

                  1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.

                  2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not...
