[REQUEST] Acer TravelMate 5742G BIOS Unlock

[chris_86]

Hello there,

I have got an Acer TravelMate 5742G notebook with dedivated Nvidia graphis card.
Unfortunately Acer has hidden the "Display Mode" option in the Bios, so it is impossible to switch between the integrated Intel IGP and the dedicated Nvidia GPU.
Could anyone of the experts here around this board help me out by unlocking this (and if possible some other hidden features)?

Here is the download-link for that Bios:

I am very thankful for any help I can get!

Thanks in advance,
Chris

Hello there. My primary problem is that my laptop temp tables sucks...if i play dota my cpu reaches quickly 90° and after a lot of throttling it shuts down instantly. I tried using RW Everything but i can't find the fan speed value. Actually i have this version of the bios...if there's a way to edit it and solve my problem it would be really great.

ORIGNAL BIOS


EDIT: In addition a way to try undervolt would be great if possible

Thanks for your answer. So it dosen't matter if my laptop is from Travelmate series right?

I will proceed to flash until i get this confirm.

My first attemp is to get control on the fan because there's no way to change its speed...i think that a modded bios could help me.

Second question: i read somewhere that acer notebooks keep settings inside the bios chip...so if i try to undervolt it with a modded bios and i got stuck in post i will not be able to recover it by clearing the cmos...am i right?

Ok friend,
I will explain how to check bios compatibility !
Download your last Bios and  try to looking for your MoBo laptop infos !
Now You have got MoBo name and You are a step forword, next step is find all
laptops which Mount same MoBo, so find and download Service Manual for your laptop and look for more infos (many times is wrote into laptops list)
or looking for It on internet, now You have a laptop list !
Now download a Bios with same release as yours for another laptop into list :

Acer Aspire 4745 - G - Z  - 4820  - G - T - TG - TZ - TZG  - 5820  - G - T - TG - TZ - TZG - 5742 - G - Z - ZG - Packard Bell EasyNote TK85 - TK87

Acer Aspire 4745 - G - Z  - 4820  - G - T - TG - TZ - TZG  - 5820  - G - T - TG - TZ - TZG Stopped 1.25

Acer Aspire 5742 - G - Z - ZG -  Packard Bell EasyNote TK85 - TK87 Stopped 1.30

Acer Travelmate 5742 - G -Z - ZG Stopped 1.30

Yours :
Acer Travelmate 5742 - G -Z - ZG  Bios v.1.30
Acer Aspire 5742 - G - Z - ZG        Bios v.1.30

You have to do an Hex Byte by Byte Compare between these two files and if they are equal You have done BINGO !!!

Every Bios for that laptop is good as MoBo are the same !
Many manufacturers Build different laptps based on same MoBo They are different only for CPU, PCI vendors, GPU, etc. and at last for price, but Heart is the same !!!
So use this good tool Beyond Compare and do an files hex compare by yourself (just to learn) and let me know !

Beyond Compare :

Acer Travemate 5742 1.30 :

Acer Aspire 5742 1.30 :
http://global-download.acer.com/GDFiles/...ep3=ASPIRE 5742&OS=ALL&LC=it&BC=ACER&SC=EMEA_17

Look by your eyes and trust in Me !
Many Acer Bios have Fan Control in Bios and I think this too, but normaly is visible so if into your is not present is the same into this one (they are equal ) !

Attached Bios Modded files ..

Really thanks a lot mate! I trust you but i get it a shot and checked by my own to...and the bios releases are exactly the same! I will flash it now.
I hope there is a way to control this [censored] fan...i always get a shutdown every time it reaches 90° and fan dosen't even go to its maximum speed.

Is safe to try to undervolt my i3 with this modded bios?

[BDMaster]

I don't know but there are many thread from Rajkosto on MDL or Notebookreview and here too, so search them and I think You'll find the answer !
