Lenovo 330-15ich dead

Re: Lenovo 330-15ich dead

I inserted the chip and got something like this:

The computer is now powered, when I press the power button, high and low frequency sounds are heard sequentially from the processor.


Also, when I press the power button, the led next to the charging socket blinks in sync with the sound of the processor.

When I put the battery, the device turns on but I can't get a display..

Is the ram removeable on this model? If yes, remove it and check if it complains with a POST beep tone pattern to note that the ram is missing.

Hello

I realized later that the problem is as follows:

When I insert the battery into the computer, the battery first draws 0.20 amps, after 3 seconds it starts to draw 1 amper


I thought the charging current was the computer's stolen current because the starting current was lit


Later, I realized that when I actually press the on key, only the start LED lights up, but the system does not turn on. So it probably needs to be programmed ec, as the respondent said beforehand


There is someone on Youtube who manages to program without a programming device, with only a simple eprom programmer, but our io chip is not the same


How to program this io chip with a bios programmer


Note: the bios programmer I have is a sofi branded mid-range programmer (I don't remember the model), but it is a device that I can program by selecting the model written on the chip from the interface and programming
(I don't think my eprom programmer has an IO chip in its interface)

If the EC was from same board, then it does not need programming(Unless the firmware in the donor ec is also corrupt). You need a dedicated SIO programmer like SVOD etc to do this job.

No, the ec is not from the same card, it is not a different version of the card I have, the computer I am taking the ec from is a few sub-models of the one I have, and the cards are completely different.


So I think the ec in io doesn't match, it's like removing an ec bios chip from a different motherboard and plugging it into my own motherboard.

Re: Lenovo 330-15ich dead

Yes, In the current case, EC needs programming as donor/receiver are not exact same board.

Re: Lenovo 330-15ich dead

Yes, it is certain that it should, but I don't have an io chip programmer. Not in a place I know. How am I going to program this?

Re: Lenovo 330-15ich dead

I'm sorry but you need a sio programmer and there is no other option. Check if pre-programmed sio is available in your location or not(Unfortunately we dont have such an option in India). Else, try locating a repair workshop who have the necessary tools to do the job.
