Good evening

I've just received EZP2019 by mail today and read the bios.
Though the EZP2019 does not self declare the correct chip when I push test!!
The software reports 93_EEPROM, ATMEL, AT93C46@16

However selecting SPI_FLASH, Winbond, W25Q128JV, Size 16 MB I managed to read the attached bios, where I could locate the SN in offset 005EA080 :-) Ie. some of the data is not corrupted.

V/r Niels

PS: how do I add the correct chip type to the EZP2019 chip database?

Flex 5-14ALC05 Laptop (ideapad) - Type 82HU

[Nielsm]

hoaca388, thanks a bunch. That worked like a charm 🙌


Let me elaborate on my way to success with EZP2019 programmer acquired from Amazon with 1.8V adapter (note: there's a newer version EZP2023. The software recognized the 2019 version however the chip database did not contain Flex 5 14ALC05 Winbond W74M12JW bios chip either).

1) saw a bunch of YouTubes irt. CH341A and EZP2019 how-to-program and do's/don'ts. I really considered afterwards if I should have bought en CH341A or maybe even the newer version CH347T / F (able 1.8 volt)
2) read a bunch of posts to include this awesome collaborate website 😀
3) how to place the in situ chip reader irt. pin 1 - 8
4) read up on Winbond.w74m12jw rev b data sheet to verify voltage usage (ie. do use 1.8 volt adapter)
4) troubleshot how to use the 1.8 volt adapter with the EZP2019 including how to place both adapter and in situ chip reader - ie. how to orient pin 1 right from the motherboard/bios chip to the EZP2019
5) use of software including setting variables to reduce interference, double verification of reading bios and Erase bios before writing then verifying bios data (Lesson Identified: if you only write - verify it's gonna produce an error)

Hi! I have a laptop that does the same issues. Power button blinks, caps-lock lights and no blink on ESC. This is what I have on the back.

How can I backup? Cause I dont think I have it. Right now, I've done the FN+R key-combination with the stick I plugged in changing to bin, wph and rom formats and still nothing. Everything stays on but the screen is black.

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Hi peste! Thanks for the video! Unfortunately, I do not have one, and I dont have the money. Any other choices?

Have you tried pressing the novo button https://psref.lenovo.com/WDProduct/I...Flex_5_14ALC05 .If that doesn`t work your only option is to buy a cheap programmer EZP****/CH341A and try to fix it yourself, or take it to a repair shop, where it will cost a lot more money.

Do I have to hold the Novo button or how?
Thanks!

UPDATE: Pressed it, still does nothing.
