Acer Aspire E5-511P :: No WiFi When Booting On USB Drive (legacy - Not UEFI)

Nov 10, 2014

I have a Acer Aspire E5-511P with bios Insydeh20. On UEFI it does boot USB-drive, even with passwords set. It boots on USB-drive with legacy set, but now my Wifi doesn't work. On older laptops no issues with UEFI, I just had to set boot order. And Wifi works just fine.

Dell Inspiron 15R-5521 :: Difference Between UEFI And Legacy And Why Can't Install Windows 7

Nov 16, 2014

What's the difference between UEFI and Legacy and why can't I install Windows 7? I put the Windows 7 CD into the CD-Rom and the installation doesn't start up. It does start up only when I change the bios to legacy. What's the difference between UEFI and legacy? Is it possible to install it on UEFI? If not, if I will install it on legacy, will everything be ok?

Acer Aspire E5-511P-C98M :: Touchpad Isn't Working

Sep 2, 2014

I have a Acer E5-511P-C98M and the touchpad stopped working. I have seen looking through other comments about this product that going into ELAN might fix the problem. Well if that fixes the problem I can't find it under Program Files. And i have also read it might be due to some Microsoft download....

Acer Aspire E5-511P :: Password Control Can Be Changed In BIOS?

Jan 8, 2015

Acer manual suggested password control can be changed in BIOS. I have Aspire E5-511P. The security page in BIOS does not work. I can scroll with arrows in other pages but nothing happens on Security page. Password at boot has Disabled but every boot asks for password. Is there a repair for BIOS? Also, the Support page on this site does not recognise my model of Aspire.

Lenovo T400 / T500 :: ThinkPad T540p / Unable To Select UEFI / Legacy Boot In BIOS / Startup

Aug 7, 2014

I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below  these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.

Dell XPS 17 L702X :: How To Enable UEFI Booting

Dec 8, 2011

Is there any way I can enable UEFI booting? I've found out Windows 7 supports it (with GPT disks as well) and Windows 8 is going to use it. This is also very useful for fast booting and Linux works very well with this (I know you don't support Linux). The main reason is so that I can have more than 4 partitions which is only otherwise possible using Extended partitions which don't play nicely with installing Windows on them. If there is a firmware I can test which may not be fully compatible with BIOS booting, I'm willing to use it as I don't need this feature at all. I also noticed there was a disabled option in the firmware provided which allows you to press F11 to boot into an UEFI shell, is there any way to enable this too?

My charger end keeps on falling out of my laptop and is very loose. How would I go about getting this fixed?

The A12 BIOS seems to keep my fan constantly on (only just on though). Was there something that was changed in the firmware to cause this?

Some people have reported having the BIOS versions A13 and A14 installed on their new L702X machines. What are the changes in these firmwares and are they for specific configurations?

Acer Aspire E15 :: Can't Boot From USB (UEFI)

Feb 18, 2015

I'm having getting my USB stick recognized as a bootable device (installing windows 7 onto a system that came with windows 8.1 pre-installed, no optical drive)
System: Acer E 15 (E5-571), BIOS V1.15 (UEFI)
What I've tried:-Disabled Secure Boot
-Created bootable USB stick with Windows 7 iso, via 'Microsoft USB/DVD Download Tool' (on alternate Windows 7 system)
-Created bootable USB stick with Windows 7 iso, via 'Rufus' (on alternate Windows 7 system)
-Windows 8.1 Advanced Restart -> Boot from UEFI USB Device (No UEFI device recognized) 
What worked:-Enabling 'Legacy Boot Mode': USB stick was recognized upon boot and loaded Windows Installation.  HOWEVER, Windows 7 won't instal to a GPT formatted drive under Legacy Boot Mode.  I've read booting in UEFI mode is the only way to get Windows 7 to install onto GPT.
What I don't want to do:-Format the drive, change drive mode to MBR to instal Windows 7.  Why?  Because then I'd loose the factory installation of Windows 8.1

Acer Aspire E1 510p 2671 :: How To Disable UEFI

Jan 26, 2015

I am simply trying to boot from a USB or the disc drive in an Aspire E1-510p-2671.
I have set the boot priorities correctly.
I have turned SecureBoot off.
I have turned on the F12 boot menu.
If I turn the machine on and let it do its own thing, it loads Windows 8.
If I tape F12 to go to the boot menu so I can manually select something, my only options are Windows Boot Manager, or
If I have network boot enabled, I get two network boot options.
I cannot change SATA mode off of AHCI, and I cannot change boot mode off of UEFI. I have scoured Google for this issue and it seems loads of people with Acer laptops cannot boot from anything other than their HDD. Changing the UEFI option has fixed it for everyone I have seen able to switch it, but I cannot switch it. What is going on? Why am I being blocked from booting from particular devices/ports? Makes no sense.

Acer Aspire V3-571g :: After Upgrading UEFI - Can't Access Settings

Oct 26, 2014

After the upgrade to the current UEFI firmware, when I try to access to settings the BIOS ask me for a password. I'm absolutely sure I have not set any password (I hate BIOS passwords). Now I need to start from a USB pendrive and I can't change the startup sequence.
I've read the post about how Acer can support on lost or forgotten passwords("there are very few if no options available from the end user side"), but in this case I've not created any password, as I said

Acer Aspire E5-571 :: Impossible To Install Windows 7 In UEFI Mode?

Feb 26, 2015

For the last 2 days I have been trying to install Windows 7 x64 in UEFI mode on my laptop but it seems entirely impossible. Whatever I do, the boot menu (F12) just won't show any UEFI devices AT ALL, just the normal DVD and/or USB options. Obviously when I try to boot from either normal DVD or USB, Windows 7 setup freezes at the "Starting Windows" screen, I'm pretty sure that's because it is not running the EFI bootloader of the setup.
For the record, I can't just install Windows 7 in Legacy/BIOS mode because it is then impossible to install the Synaptics Touchpad driver under Windows because the Touchpad device is not discovered for whatever reason.

Acer Aspire V3 571G :: BIOS V1.13 Doesn't Have UEFI Settings?

Nov 6, 2014

So I have bought this Acer laptop for 1 year, and it's BIOS came with V1.0 didn't have UEFI setting, the default is LEGACY. After trying updating that BIOS version to V1.13 successfully, I still don't see the UEFI setting, when I check in a software called HWiNFO64 Program, it says my laptop BIOS is capable of UEFI BIOS. So my main questions are....How can I have UEFI setting in my BIOS? What should I do? 

My specs: Intel Core i7-3630QM 2.4GHz, Nvidia Geforce GT 640M 2GB, RAM 8GB, HDD 750GB, Windows 7 Ultimate SP1 x64 (Will upgrade to Windows 8.1 Pro x64 if I can change my BIOS to UEFI boot).

Acer :: Aspire 9500 Booting

Mar 30, 2008

last year i formated my acer 9500 laptop and got a normal home win xp. A couple of days ago i got a hold of my original acer system cds and i decided to restore my system back.

Everything went well until the install finished; I was in windows and the first time i restarted the laptop it didnt boot back in win xp. When its about to start booting windows it stops and all i get is a black screen and a flickering white small line on the top line. I tried reinstalling the original system again and the same thing happends; after the first restart it doesnt want to boot xp.

I started reading forums and found out that if i press alt+f10 it might fix the problem.

It worked, if i press alt f10 before it reaches the black screen it loads into xp. This is the only way i can load it. As i read i got the feeling i might have messed up my MBR.

Im not sure how this all works but i have a hunch that my laptop doenst know where my xp is when its supposed to load it and by pressing alt f10 it somehow temporarly fixes that.

Is there any way to permanently fix this ? Some pple said that if i ran a normal non-acer win xp cd and ran some sort of MBR fix it might solve my problems. Im getting a cd from a friend in a couple of days . Is there any other way i can fix my notebook before then ?

Its not a big deal if i have to press alt f10 everytime i restart but its annoying and i have a hunch ill run into trouble later on.

Acer :: Aspire 6920 Not Booting

Dec 13, 2009

I was installing Windows 7 on my Acer Aspire 6920.

It had Windows Vista installed. I deleted all the partitions including backup (Yes I found out that was stupid), and tried installing Windows 7.

It wouldn install Windows 7 so I went back to Windows Vista. I found my recovery disk and it sort of worked. There where no errors in the setup but when I start my computer it doesnt go to Windows.

It has a black screen with a white _ blinking.

Acer :: Aspire 5536 Slow Booting

Nov 16, 2009

I have a brand new Acer Aspire 5536 Notebook. It came pre-shipped with Vista which I did not want.

So I tried a fresh install of Win7 - formatted drive etc,. Machine takes 5+ mins to boot so I put this down to a compatibility issue and tried XP. However I have the same problem, fresh install with only updates installed and it takes forever to boot (even longer than Win7).

Once booted performance is ok (in Win7 it was near perfect). Any ideas, I am beginning to think it is defective.

Acer :: Aspire 7720- Booting And Sound

May 13, 2010

Acer Aspire 7720 I've got. Basically it has both the common boot-up freeze and crackly/distorted sound problems that appear to be common. I understand that the best, albeit riskiest, way to solve these is to flash the bios to a more recent version, which I am prepared to do.

However - the bios upgrades are not available from Acer's own support site, and I don't know where else I can find them, and I have tried.... Is there anyone who can help me locate them? The problems with this laptop are driving me spare, and I really can't afford another, or even another motherboard, just yet.

Acer Aspire 6530 :: System Not Booting

Nov 4, 2014

I have had my acer aspire 6530 since August 2009 now. It never had any major problems. Sadly, after comming back from New Years Eve 2014, I wanted to turn it on, but it just started up for around 4 seconds and then started to reboot again and continued so, until power was plugged out or shut down. There was only a black screen, without BIOS etc.I've searched forums for a solution, all of whom resulted in failure.

Dell Inspiron SE 7720 :: UEFI Boot From USB Drive Is Not Working

Feb 15, 2013

I have just purchased a Dell Inspiron 17R Special Edition 7720. It came with a preinstalled Windows 8 (so 64-bit and mandatory UEFI boot). I want to use Linux (more specifically, Archlinux) for work and Windows for games, so dual boot is needed.

I almost completed the Linux installation except for the bootloader: I need to boot Linux from UEFI and didn't manage to do it so far. Here is what I did after I received the PC:

-Disabled Secure Boot; updated BIOS to version A12
-Resized the main Windows partition and created a few partitions for Linux;
-Switched to legacy boot mode and managed to boot a MBR-bootable Arch linux installation USB drive;
-Installed most of the system switched back to UEFI boot mode, Secure Boot off.

At this time I needed to boot the kernel from UEFI for the bootloader installation program to have mandatory access to the EFI environment variables. So I created an UEFI-bootable Archlinux installation USB drive (with a FAT partition) but so far I couldn't manage to successfully boot this drive from UEFI instead of Windows 8.

I think I really tried every single combination, such as:

different USB ports; different boot entries created with F2 boot setup, with different parameters; different orders for the boot entries; hit my boot entries directly within F12 boot menu.

No matter what, in UEFI mode the system always boots the Windows partition.

Also, I could not find any relevant manual or software documentation about the A12 BIOS on the Dell site, did I miss something?

The solution that the user described in this thread to UEFI-boot to a DVD did not work for me with a USB drive.

Acer :: Aspire 7720G WLan And Booting After Sleep

Oct 21, 2008

I bought an ACER Aspire 7720G Intel Core 2 Duo with Vista SP1 3 weeks ago and have now some problems with my WLan and with booting after sleep. WLan only works when I restart the computer after swiching on the WLan connection either by pressing the WLan button or by activating the connection in "networks and sharing center" (at least it works then, but it's annoying to restart the computer all the time). Since I use WLan at home I get a message while booting the system (Broadcom UNDI PXE.... Client... MAC ADDR:... GUID... DHCP ...not found..blabla). I use a Lan connection at work and here I have no problems yet. My second problem is that my computer really stays asleep after I woke it up from sleep or just if I would not use it some minutes. It does not show any system related information anymore and I can only restart it again. I have looked up my BIOS and it is Version 1.44 (read the thread about the BIOS problems),

Acer :: Aspire ES1-511 / Mouse Doesn't Work After Booting From The CD

Nov 4, 2014

Just bought an Aspire ES1-511. Not my first Windows 8.1 laptop, but my first with UEIF firmware.
I've been trying to boot Driveimage from CD to do an offline backup, and guess what, it wouldnt recognise the CD as bootable. Fixed that by setting the boot type to "Legacy" in the BIOS and it boots fine.
My problem is that the mouse doesnt work after booting from the CD. Watching the behaviour of the mouse, it powers up when I press the power button, but powers off immediately the POST completes.
If booting Windows from the HD, power to USB is restored as soon as windows loads to the lock screen.
