Hi guys, I need new BIOS for Lenovo L14 Gen 2
HL4A0/HL5A0 NM-D271 Rev 2.0
Model 20X2S5XB00
S/N PF3NPKZK

I attach dump of original BIOS that was corrupted and also dump of 16MB chip
With another BIOS (both chips) from this forum the laptop does not start. White LED flashes 3 times, the batteriy is charging. Without battery it takes 1,9 watts at 20V
If my original BIOS cant be fixed do I need to flash EC chip?

Re: Thinkpad L14 gen2 Intel BIOS needed!

are you sure that u2104 chip is installed from factory or you installed it yourself. i have the same motherboard with the same color but no chip

It's work. Thank you very much !

are you sure the

[brzostos]

The 20X2 has 2 bios chips, 32MB and 16MB. If U2104 is where the 16MB chip should be then you will have to get one.

I only have the U2101 32MB chip on the board, there is no U2104 and it looks like it was never there.

The laptop does not respond to the power button, voltages of 3.3v and 5v are present. On the 3.3v switch it drops to 0 when pressed, charging the batteries.

After connecting the power supply, the battery charging LED lights up and the power LED flashes 3 times.

The U2104 chip is not on the board

The original upload looks damaged to me because it is very different from the ones I downloaded here.
