Ideapad 5 - 1411L05 - BIOS
Model: 81YH
MO: MPNXB05150FG
MTM: 81YHCT01WW
I have an Ideapad 5 that will not post, the fan spins and the power button is flashing.
I removed the BIOS chip and have attached a copy of the original BIOS bin file.
I downloaded the latest BIOS file for the device and extracted the ROM image, which I then converted to a BIN file using the software supplied with my XGPro 2. I have also attached this file to my post.
Unfortunately, the laptop is still not posting and I am basically out of knowledge and ideas.

840 G3 BIOS unlock request
I tried the HP Unlock Tool on this BIOS dump but it did not work, the BIOS still has a password.
Could someone please unlock it for me?
Any assistance is appreciated.Last edited by SMDFlea; 04-10-2023, 11:33 AM.Leave a comment:

Re: BIOS Chip location on HP Elitebook 840 G6
It does look like a BIOS chip, I was looking for the location of both BIOS chips for this board. Its a 256Mb chip - so I am guessing it is the wrong chip.
There are several posts from members who have backed up both, I was hoping one of these members would have replied - with the location of both of these chips.Leave a comment:

BIOS Chip location on HP Elitebook 840 G6
I have an 840 G6 and need to remove the BIOS password.
If I have read correctly this can be removed by editing the 32Mb BIOS chip.
I believe I have located this BIOS chip (refer to image) but would like to know for sure the location of the two BIOS chips on this board.
Any assistance would be appreciated.... -

Re: Acer Spin 5 SP513-51 New battery not charging
NO, it is a new battery and has zero charge. The laptop will not power on without the charger.
The laptop will also not charge the old battery - initially I presumed the battery was needing to be replaced.Leave a comment:

Re: Acer Spin 5 SP513-51 New battery not charging
Thank you for the reply, yes the switch is working.
If I hold down the switch and plug in the charger I get 12v on the battery connections for a few seconds then it goes to zero.Leave a comment:

Re: Acer Spin 5 SP513-51 New battery not charging
Thank you for the reply Stingerchamp.
I have not been able to find any motherboard ID, there is zero voltage on the battery pins and I have not been able to locate the charging IC.
There is a tactile switch on the bottom of the motherboard that needs to be pressed to allow the battery to charge - so it is difficult to measure anything battery related....Leave a comment:

Acer Spin 5 SP513-51 New battery not charging
This laptop is not charging the battery, I am aware of the battery tactile switch on the bottom of the motherboard.
I have reset the BIOS etc.
I cannot find a boardview for this model - I suspect a faulty charging IC
Any advice would be appreciated. -

Re: Satellite L50-B-1NX
Hi Guys, I cannot get a clearer image of this component, my phone just refuses to focus on it.
I agree, this looks like a crystal, if you guys are confident that it is 32KHz is there any reason why I could not just purchase a generic SMD replacement?
Example: [url]https://www.ebay.co.uk/itm/CRYSTAL-32-768KHZ-9PF-SMD/124226022348?hash=item1cec72abcc:g:mNkAAOSw4yte6fMm[/url]
I presume there is no schematic/Boardview for this motherboard?
Any assistance is appreciated.Re: Satellite L50-B-1NX

Re: Satellite L50-B-1NX
Thank you for the reply, it is not going to be easy getting a closer photo, the component is tiny. I will give it a go.
Also - would this component stop the laptop posting?Leave a comment:

Satellite L50-B-1NX
This laptop will not boot up, I have examined the MB and found a blown component.
Motherboard: da0blimb6f0 rev f
Can anyone identify the blown component?
Any assistance would be appreciated....
