    I dropped my H4 and it does not work!
    It was a relatively light drop as well on carpet. So I am bummed. :(
    Does not work when plugged in via USB nor AC power or Batteries, nothing!
    I guess I will have to look for that warranty...

    Same thing happened with mine.  It was a decent drop onto hard floor, but still works when plugged in.  I'm gonna try the battery terminal fixes and hope that works...

    I have the same problem with the H4 after the fall no power from the battery. I checked in the middle of no damage. It dodarkowo one very bad phenomenon. I strongly heats the coil L202 with an internal power supply module. Does anyone have a schematic diagram of H4?

Take out the two screws then pry the case open and it will come apart. I don't think it is the switch btw. I think there is something wrong with the voltage sensing of the unit. Mine won't power up on alkelines but will power up on nimh's of slightly lesser voltage, but then says battery low.....

Ask your dealer, the one you bought it from. They may suggest an easy fix or guide you best on how to get it repaired, or at the very least suggest a place near you to have it repaired. If your dealer doesn't know, ask any Zoom dealer for repair info. Meanwhile, I assume you've checked your battery compartment to make sure the terminal connections are not loose (and of course that you've tried new batteries - :) ). Also, check Menu>Battery to see if alkaline or nickel batteries is checked. Finally, try removing your SD card and re-inserting, (even re-formatting the card, perhaps, but trying merely re-inserting first). But make sure any songs/info on the card are backed up first, because you will lose info if re-formatting the card. (For that matter, you could try a new card.)

My Zoom H4 will no longer power up with batteries. (yes even fresh batteries) only works with AC adapter. There was only one possible solution that makes sense and that would be concerning the little switch that disconnects the battery power once external power source is plugged in. I'm sure that I can repair this except, I can't seem to take the darn thing apart to do so. I've removed all visible screws and can't seem to dismantle it. It seems very fragile and I would hate to crack the casing. Does anyone know how to open this thing up?

    I had the same problem. It was the battery connection on the flap. It looked clean but, closer inspection revealed it was corroded. I took fine sand paper and cleaned it and the H4 now works fine on battery power now.

Hi! I placed a bid on Ebay, on a used Zoom H4 and didn't read the fine print! I now notice that the seller says that the condition is good, but the battery operation doesn't work - it only works with the...


Usually the problem will be with the battery contacts. Often corrosion due to leaving batteries in too long or the spring contacts, don't. Another harder thing is the adapter connector often has a spring blade that contacts the center pin when adapter is unplugged to switch to battery. These get bent and are a chronic problem for devices that use either adapter or battery.

This isn't a solution. It is a reaffirmation that you aren't crazy!

My Zoom H4 will no longer run with batteries. If I use AC adaptor it works fine but I get nothing on battery power


Probably the connector where you plug the AC adapter into has a switch contact that disconnects the battery when external adapter is used and it has gotten bent so when the adapter is not plugged in, it no longer makes contact to the battery power. This is pretty common for devices that use both battery and adapters.

Zoom H4 does not power up on battery power.


Probably two years too late, but I recently got a used H4 and it was having this same issue. Upon reading the documentation, it seemed as though it required a specific type of AA batteries. If you update the firmware (mine was 1.3) to the latest version (currently 2.4), you can toggle the battery type under the menu (most likely alkaline is what you want). It also added lots of other great features!

Connect to PC does not work


You need to upgrade the H4  firmware from Zoom website

You will need an external SD card reader.
Good Luck

Cannot connect to PC


Do you have an SD slot in your mac? plug the sd card there and see if it works. Erase manually the files (leave the system files) and try again with the H4. Luck

Display reads "No Card"


Zoom h4 supports cards up to 2GB. And, I'm almost sure, this is a thing that can't be upgraded through software.
