Re: Acer TravelMate P273-m bios
Could someone confirm this is an EC file, this was included in the 2.03 version download, it has the 4 mb 2.03 version rom and a .ME file which is 2MB.
IS this an EC file for the EC winbios chip of 2 mb?
Confirm please, and if so is there anything I need to copy anything out of the ec bios dump or no need.
Can also compare with the 2MB bios I posted here in the beginning of the THread where i thought it was the MAIN bios..
THANKS....

Re: Acer TravelMate P273-m bios
I have downgraded the bios to 2.03, i've done this via the normal way.. execute insydeflash.exe..
Laptop seems more stable but still has issues. I'm not sure the EC was also flashed.
Is it possible to dump the EC bios without attaching a clip / desolder? Just via a software way?Leave a comment:

Re: Acer TravelMate P273-m bios
Definitely Bios related. Started the laptop this morning only on battery, doesn't show signs of life. Remove battery and put back, and it works again.
The problem I described earlier is mostly to do with the laptop going into sleep or hibernate mode, this will cause a shutdown or a reboot with a windows error.
Hope someone point me in the right direction on how to fix this problem.Leave a comment:

Re: Acer TravelMate P273-m bios
Also I could flash just the 2MB EC chip with ch341a, but I have no fresh stock.bin for that. For the 2.11 version..
Anyone have it or can make it?

Re: Acer TravelMate P273-m bios
The laptop can run again. Great. Thanks for the help for that.
Though I'm now having trouble with some things. When the laptop lid is closed and open again, the laptop gave blue screen and reboot. Other time it just stay black it went shut down and other time it just reboots and reboots again. Also sometimes the laptop not respond on the power button, after two times boot and it's off, no respond to the power button. I take out power supply, wait a bit and connect, then starts again??
Also the laptop does not respond to the...Last edited by fyzeler; 08-15-2020, 03:16 PM.Leave a comment:

Re: Acer TravelMate P273-m bios
Hi, thanks will try.. About the EC bios, I just leave it the way it is? The 2 mb ones I posted earlier is actually the EC bios (KBC?)
I have to copy over at 33B000? The file you posted does not contain any of my laptop info.. Please clarify, thanks....Last edited by fyzeler; 08-15-2020, 03:28 AM.Leave a comment:

Re: Acer TravelMate P273-m bios
Anyone can fix the 2.03 bios that I earlier already posted with the 2.11 dump I made. Copy over the serial / keys and so on. Im clueless how to do so.
Or any other fix..Last edited by fyzeler; 08-15-2020, 01:48 AM.Leave a comment:

Re: Acer TravelMate P273-m bios
Question, the stock bios does not have any info like the serial number of the laptop and stuff like that.
Is it necessary to add these to the stock bios or will the laptop run without filling these things in?
I want to flash v2.03 back in but it is of course not a backup or a dump, it is a stock bios from Acer, will the laptop run like that and perhaps when the computer runs you can fix these afterwards ?
I have no clue how this works, but im doing my best.
I also do not understand why the 2.11...Last edited by fyzeler; 08-14-2020, 02:43 PM.Leave a comment:

Re: Acer TravelMate P273-m bios
I've dumped a correct one now I think. I desoldered the chip and soldered to the adapter. I have compared the dump with the v2.03 I downloaded and they match 99%. There is a little difference but definitely there are parts different. Perhaps This dump is the 2.11 one, I can't see. But when I flashed the computer the first time the normale way from 2.03 to 2.11 it did go to 100% and give no fault that the flash had failed.
Curious what you think is going on? Bios Corrupt or what I wonder.

Re: Acer TravelMate P273-m bios
Yes but I have problem reading the 4 MB bios chip from the motherboard. It give a different dump everytime i make a dump / read.
The 2 MB chip is always the same dump, the 4 MB bios chip 25Q32BVSIG gives a different dump every read.
This cannot then be trusted, the dump is no good. I have no idea how to fix it. As I said above I already tried with power supply, no change.
The dump file is different still everytime I do a dump / read and is gibberish. Any idea?
With the Ch341a programmer by detect...Last edited by fyzeler; 08-13-2020, 09:39 AM.Leave a comment:

Re: Acer TravelMate P273-m bios
It seems I get different HEX outcome everytime i read that chip, what does this mean.
When I read the 2MB chip, the result is always the same. So my clip is no problem. When I read the 32mbit chip that i just found, 25Q32BVSIG it gives me a different HEX outcome all the time.
Does this mean this chip fail, the clip cannot connect proper or the chip maybe needs the motherboard to have power from power supply?
I used CH341A programmer 1.34 and ASprogrammer, everytime i read out the chip it gives different hex result....Last edited by fyzeler; 08-13-2020, 08:24 AM.Leave a comment:

Re: Acer TravelMate P273-m bios
Oh wow, you are right. There is another chip on the backside of the motherboard!!
Im so noob.
The one on the backside says. 25Q32BVSIG.
This mean this one is 32mbit, this means I can flash the 4mb rom?? I mean even the official one in the 2.03 of my laptop.
Can you explain what the other chip is that is 2mb? Is that KBC mean for start computer and LED lights etc? I shouldn't flash that one correct?
Because my laptop still can start and have led on, also fan is running. Just screen black...Leave a comment:

Re: Acer TravelMate P273-m bios
Have not tried, compatible?? Also in the zip there, the one that is 2mb says hub.bin and the 4 mb one says KBC. What does it mean?
My chip can hold only 16mbit = 2MB. The only one I could flash is the Old v3-771g_HUB.bin
You think I should flash that one and see ?Leave a comment:
