Hasee M2152 won't boot to any Drive + f2 and f10 not responding
[B]Hi Everyone,[/B]
I'm facing a problem with a [B]Hasee m2152 AIO pc[/B] that cannot boot to any drive (hdd, ssd, pen drive,...) and the f2 and f10 prompt is showing at start-up but nothing respond.
The problem started after making some changes to the bios settings precisely after enabling the fast boot option.
I attached a copy of the bios with hope someone can clear the changes made.
Also The clear-cmos jumper is useless

Re: LA-E791P works in battery only
[SIZE="3"]Thank you for the addition on olive oil, this year the prices have been too inflated for ordinary citizens and the quality is unknown.
Let's hope that a quantity of the good product can reach good people like you.
In any case, for the repair of the motherboard, I will follow your instructions and I will inform you of the results.

[SIZE="3"][COLOR="Blue"]Thanks a lot for your help.[/COLOR][/SIZE]
Because of multiple attempts to get a good measurement of R1, I destroyed it.
In any case, I will try to get another similar one from old motherboards because there are no nearby suppliers and purchasing from the internet is very complicated in my country.
I will inform you of the results as soon as possible.

Re: LA-E791P works in battery only
Thanks for help.
According to datasheet
• 0: AC Adapter is not present (ACDET < 2.4V) <default @ POR>
• 1: AC Adapter is present (ACDET > 2.4V), no deglitch time, read only
I attached two images for the power adapter that I use.
Can the two resistors [B]R1 430k[/B] and [B]R2 66.5k[/B] be the problem and need to be replaced ?Re: LA-E791P works in battery only

Re: LA-E791P works in battery only
Hi everyone,
I'm facing the same problem.
The motherboard model is:
[B]CSL50/CSL52 LA-E791P
REV:2.0
2017-07-18[/B]
I joined an image to the post with taken measurements ( The multimeter that I use is not perfect so excuse me for any mistake ).
[COLOR="Red"][SIZE="3"]I'm using the schematic from this post[/SIZE][/COLOR]

Re: Acer aspire 7535 no boot after bios flash
Thank you for your interest.
The bios model is: [B]winbond 25x16avsig[/B].
In any case, I got another bios from an old motherboard with 2mo of size that I programmed using the dump provided by [COLOR="Blue"][SIZE="5"]volinakis[/SIZE][/COLOR] and the laptop started up again.
It's not my laptop so I would return it to its owner in the same initial conditions to avoid problems.

Re: Acer aspire 7535 no boot after bios flash
Thanks for the help.
I think something is wrong with my bios chip. When I try to erase it, I'm still getting content when reading the chip.
Also, when I use the verify button of the programmer, I'm getting an error.
A picture is attached to the post as a prove.
If the chip is corrupted what are the possible replacement ?...Leave a comment:

Acer aspire 7535 no boot after bios flash
Hello everyone,
motherboard:
08255-2
JM70-PU MB
48.4CE01.021
Acer aspire 7535/7535g/7235
model No: MS2262
Initially the laptop suffered from a battery charging problem.
I tried to do a reset using the button on the motherboard.
After that, I no longer have a display so I flashed the bios with a dump downloaded from the internet. (Attached to that post)
Now I no longer have a boot.
So, I recovered the bios from a backup but still no boot. (Attached to that post)
Please help me.... -

Samsung NP300-V5A_Scala3 15 repair touchpad bouton
Hello everyone,
I need to repair the right touchpad button but I don't know where to solder a bridge in the motherboard.
I found the motherboard schematic but not the board view.
I attached all possible files to help accelerate finding the solution (I hope so).
