Lenovo flex 5-14alc05

[fonteene21]

read the post above and this..the bios from the post above is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

Dear Pest,

Thank you for your help.

Using the HxD program (which is available for free online),

both BIOS files (copy and paste) worked successfully.

Now I can fix it myself in the future.

The screen is completely black, the Caps Lock light is on, the Esc light is off, the power button is blinking, the CPU is hot, and the fan is spinning.

After trying a normal BIOS dump from this thread, it started up successfully.

Could you please correct the BIOS information to the following?

flex 5 14ALC05
LC56-14a
S/N: R912TNM1
MTM: 82HU009XJP
MO: R9N08151800B

Please, someone help me.

Try some older bios versions. If there is no change there is a hardware issue.

Hello everyone.

The reason it wouldn't boot was hardware-related.

Even after flashing to several correct BIOS versions found here, the voltage remained at 20V 0.6A, the ESC and CAPS keys stayed lit, and it wouldn't POST.

After investigating, I determined that the chipset was overheating in a localized area, and that a chipset short circuit was the cause.

Thank you for your advice.

I've tried several BIOS dumps from this thread, but my laptop still won't boot.
The screen is black, the Caps Lock, Esc, and power buttons remain lit, and the CPU and SSD get hot.

Did I do something wrong with the new dump? Or am I using the wrong clean dump?

Unfortunately, using this BIOS didn't work either.
I tried removing the chip from the motherboard and rewriting the BIOS with a programmer, but...

Hi everyone, guys I hope you can help me, I'll start by saying I'm a bit of an idiot......

Lenovo IdeaPad Flex 5 14ALC05 I think blocked via Lenovo Vantage. The screen is black and the Caps Lock LEDs light up
s/n R91225F00
mtm: 82HU000VIX
bios ic winbond 74M12JWSIQ

I bought a CH341Apro programmer, and I thought that by simply loading a new bios I could solve the problem, but I realized that I'm a big idiot, I haven't done any assistance for 20 years from…

Try, BIOS extracted from Lenovo website, DMI+Win key inserted

worked perfect thank you.

Laptop should boot with a clean BIOS, just the S/N, MTM, model name will show as INVALID and will be missing the Win license, older version GJCN27WW is available at post 7 on the first page
Also the BIOS chip is 1.8V, did you use 1.8V adapter with the CH341A? Maybe the problem isn't the BIOS

This one unfortunately does not work. I checked my motherboard with a multimeter and all the voltages seem to be normal and pointing towards the bios or the ram. So a few qustions about the bios, does the bios version matter? For example the newer versions have the number 34, but does that really matter and would a 27 or 29 also just work? Next to that, how important is the DIM data, should the computer also start on a clean dump?

It seems very unlikely to me that the problem lies with the RAM, and I am hoping maybe I still need to figure out a correct dump

Unfortunately this one also does not work, maybe it is not a BIOS error?
I am using neoprogrammer and both the blank check and verification gave back a success
