L50-B strange behaviour

08-29-2017, 11:35 AM

Hello. This one L50-B-127 when AC adapter is plugged in it automatically turns on, same with battery, and cant be turned off.
Fan spins for a few seconds and than stops but CPU keeps getting hotter. It has all voltages from what I can tell, except BIOS VCC and signal voltages.
When BIOS chip is onboard its voltages are ~0.7V , when BIOS chip is removed voltages are 3.3V. I have replaced the BIOS chip but same thing happens.

What could cause this, faulty KBC?

Asus Chromebox CN62 - wrong chip put on BIOS reader

by BMCappelletti

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)

He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

Lenovo laptop does not turn on, what does this number mean in a BIOS chip?

by thxd43

Hello, first of all, excuse me, I am using the translator, English is not my native language.

The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.

by hotcrossedbuns999
My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
3. I could only locate two chips that look like bios chips. Could someone verify this
