Re: bios for hp PROBOOK 455 G8
Dear friends, i'm novice to forum, i can not exactly ask a question) ... I have an HP ProBook 455 G8 bricked after a failed BIOS flashing (under BIOS shell from wired connection). Do i understand correctly that DMI utility is no longer used in new models, and filling missing data in DMI is done in BIOS shell itself in MPM section? Is everything same as here? _https://www.youtube.com/watch?v=GuENOtU_B_w&t=264s
I still have a laptop warranty and i would like to know whether it is worth doing it myself (i have some experience).. ), or give it to service. Thanks for the answer.Comment

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice... -
Hello,
I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).
But today it's not accepting my password. I'm %100 sure i'm entering the correct password.
I'm trying to reset my bios without success.
I tried :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries... -
my laptop is lenovo flex 5 14ITL05
recently my power supply for this laptop developed a fault.
which caused a short in my usb c port -- verified with a new charger.
rant: so, i went to the repair tech in my country, he asked for a huge repair cost when i decided to get it done someplace else this "great person" nicked my bios chip, asked me to be aware for repair scams lol.
I was stupid and unable to find the flaw at the moment. Another repair tech told me that my bios chip was stolen and an 8mb bios chip is in place of that. he told me that a 32... -
Hi,
I am trying to fix an Acer Aspire 5542. Upon turning it on, the fan starts to spin for a few seconds and then it stops. I hear no beeps from the speaker. I have no image both on the laptop screen and through VGA and HDMI connectors.
I measured voltages, and it seems all power supplies are OK. There are 5V, 3.3V (BIOS), 1.8V (RAM), and 1.1V (VCORE).
I tried to read the BIOS using a CH341A programmer, but it did not detect the chip. I took the BIOS chip away from the motherboard, and then the CH341A detected the chip, and I was able to read the code. However,...
