Travelmate P645 - Don't update to BIOS 2.14!

Dear Forum Members,

don't update to the BIOS version 2.14.

I unfortunately did so and now I can't make full use of my 24" external screen anymore.

The resolution is now limited to 1600x1200 vs. 1920x1200 before the upgrade, using the DVI-Output of the Docking-station.

Unfortunately the description in the BIOS changelog does not say that.

The friendly hotline technician confirmed that I was not the only one having this issue offering me a BIOS downgrade, however I would have to send my PC.

Not having one week to send the PC to the Acer Service Center back in Germany, it seems I have no other option than waiting for a new BIOS-version since Acer does not permit a downgrade of the BIOS. :-(

Hoping that helps some fellow users.

Regards Siriuslux

Hello frox,

unfortunately there's no solution (yet) that worked for me.

I think I'll have to wait for Acer to make a new release of the BIOS, hopefully that'll happen soon as the crippled screen is not really good for working efficiently.

Same Problem here! (P645-MG)

Is this an issue that will be resolved by a new bios version soon?

If not, is it possible to provide an old bios version?

best regards

Hi! I got in touch with acer level 2 support and I should get a response from Taiwan based bios development team at the end of this week. I will update you with any news I get.

Hey guys, I received an email from Acer support with this zip file

https://www.dropbox.com/s/g71lrsugsgvik2j/acer_bios_downgrade.zip?dl=0

it contains pdf with instructions how to downgrade the bios to v2.0. I am thinking about buying 27" screen in few weeks so I have not tried it yet, however, it seems like a solution. Let us know if it works for any of you!

PS. I understand this seems "suspicious" coming from an ordinar user and not official Acer member, yet, this is all I can do now.

There is also a workaround for ubuntu lovers available. I installed ubuntu alongside windows, and with ubuntu you can get the native resolution of 1900x1200 on your external screen. You can test it with a linux live cd/usb. There is one important thing, however, if you want to install ubuntu permanently: Before you install ubuntu you have to switch the boot mode from "legacy" to "uefi" in the bios boot menu.
