Hi Ideapad when Plugged in 3.3vALW and 5vALW are on, but 1.05vALW and 1.8vALW absent. Power led lights and remains always on and laptop not trigger..
Found a burned spot on LV5075B IC, replaced with a new imported IC, but 1.05vALW and 1.8vALW still failing. .
EC IT8586E working voltages and signals are all ok except PBTN_OUT# 2.44V not changing when power button is pushed and EC_RSMRST# always 0.1V ??
Reflashed EC IT8586E and Main bios with newly download dump from Lenovo site to no avail.
Should I fix again a new L5075B and replace IT8586E to solve the issues....

Hi everyone

I have a Lenovo ideapad 1 15AMN7 with ryzen 3 7000 series processor.

I changed kbc (KB9052QE) and charger IC (BQ247800) due they were in faulty, reprogrammed kbc and it turns on fine, but processor run at only 400 mhz all the time.

I tried to change bios settings, installed all the drivers, using programs to change cpu settings but nothing works, I don´t know what to check.

Please you help

It is a Lenovo Ideapad 3 15ITL05. mother board HS45A/HS55A rev:1.0 NM-D461. MTN: 81X800AKSA. It has two bios chips windbond 25R64JV(8mb) and 25Q128JV (16mb).

Hey,

Then, later the laptop won't start anymore.

I've made a basic troubleshoot with my own laptop (same series)

Hello everyone, does anyone have the schematic and boardview of the NM-E331 board, I need to disable the onboard memory​

Hello, I have this board in question. When I connect an AC-DC adapter charger (without a battery), the consumption is 19mA, with only +5VALW and 3VL present. When I press the power button, all voltages appear OK, the consumption rises to 260mA and remains stable. There's no video.

My question is if anyone has this board or information on the power-up sequence, and if the other ALW voltages are present when the load is connected.

What I noticed is that at first, 3VALW and 1.8VALW appear for a second or less. The BIOS is never read. Even so, the BIOS has been reprogrammed...

Hello,

I have a Lenovo ideapad 320-15IKB. (DG42A DG52A NMB244 Rev:1.0 PN:5B20N96152 The board has an Intel Core i5 7th gen CPU.)

I connect the power supply, have 20V at some ceramic capacitors near the coils on the picture, but 0V on any coil. When measuring the resistance between the coils and ground, PL401 measures 0R. All the other coils measure at least 10R.
PU401 is a Silergy SY8286BRAC as far as I see.

What shall I do next? Shall I measure the exact resistance between some parts, e.g. capacitors or chips to ground? I have a 6 1/2 digit DMM, but...

He said bios is corrupt and flashed a new one. After i got the device i found out that my second hdd is not detected. I thought it may be damaged and ordered...
