    How to test/check ic chip?

    Hi,
    Is there any way to test/check an ic chips?
    I have only AVO meter, no scope or anything like that.
    Thanks in advance.

          So the only way is to replace them and see if the circuit board is working?

              you could check voltages against schematic

                  My simple answer is also no.
                  Sometime you may be able to test for internal shorted circuit of the IC if you know what are inside the IC.
                  For example: the SMPS IC with integrated power MOSFET, you can check to see if the MOSFET is shorted or not with meter.
                  Voltage testing also help in verification of the IC.

                      it's actually a very complex question because there are so many types of i.c.
                      i have equipment that can test logic, static memory, i/o controllers and most op-amps.

                      but it's expensive kit, and that's still just a drop in the silicon ocean.

                          by Grouickman
                          Hi there,

                          First, I'm not sure it's the right section to post for this type of device, but could not think of something better.

                          Ok, so my son (a mechanic) bought a faulty Hofmann Geodyna 6300 wheel balancer (which appears to be mostly a re-branded Snap-on wheel balancer).

                          I'm looking for any resources (doc, manuals, schematics) that would be available for this device or anyone that would have any knowledge on this particular device (or its Snap-On equivalent).

                          I'm trying to diagnose the fault(s ?), but I can't find any schematic (appart from the...

                          Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
                          by acedogblast
                          This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

                          There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

                          CH341 disconnects, test clamp not working, soldered bios chip but not erasing/writing how I fixed
                          by Sparklingx
                          Hi,
                          So i've bough a ch341 programmer, and the chip was CH341B . the test clamp was not working( when connecting bios using test clamp, ch341 device was disconnecting) I tried soldering the bios on the provided board, soldering the bios I could read the chip but could not write or erase. ASprogrammer , neo, ch341a programmer... all programmer software was hanging and device was disconnecting after few second of erase/write operating.
                          So then I have soldered a capacitor(whatever I had..[10v ~470uf ] ) from VCC to GND on my provided pcb where you solder the bios

                          now all...

                          Hello.
                          Know somebody how to successfuly test bad onboard memory and maybe even bad chip localization?

                          Have newer asus that show memory related BSOD. After reball still the same. how to test if it is some ram chip or maybe bad ball under cpu or even cpu

                          Hi.

                          I'm posting this here in part as a memo to self as well as to describe the procedure I used in case anyone else found it useful. I found a lot of the necessary information to make this work on this forum and I figured I would give something back. If this is not the appropriate place to post this, I don't mind it being deleted but I hope it can help other people.

                          I got an admin password locked HP Elitebook 840 G5 recently that I wanted to unlock. I'm a relative newcomer to reprogramming and unlocking firmware. The only previous experience I had was unlocking a BIOS...
