s7 Acer problem

Hello! I have an acer s7 391 and I have the following problem. When I enter the app menu, or when I try for example to attach a file to an e-mail in the mail application, the screen is gradually begin to look bad, the contrast and the colors change, and it's a little weird. When I swich to the beginning or to the desktop, the screen is trying to look good again, little by little. as in 5 to 10 seconds.

The problem is that I noticed that this problem will NOT occur when the computer is in charge. What happenes only when it is on battery power. I already checked for the settings, there is no problem. plugged/unplugged settings are the same, but without effect.

the service already changed my screen. the problem may be the motherboard or video card? or what it might be? has anyone noticed this problem with his laptop? Thank you!!

As freeza indicated on your other post on this subject, please contact the service.

We suggest to contact technical support in your region for further assistance in this matter.

  • Scalling v3 - 372 screen Acer problem

    Hey, I recently bought an Acer laptop of v3 - 372 without OS pre-installed, and I installed windows 10, then the drivers from the acer site.

I tried to change settings in the Intel HD graphics Panel, but this does not help, any ideas on how to solve it?

  • Market problem laptop Acer problem

    Hi all

    I wonder if anyone has met, or heard of this problem.

    I have a laptop Acer Aspire 5745 w / 640GB HDD and 8 GB of memory running with Win 7 Home. I have about 3 years.

    A year or 2 there, he began to develop a market problem. I noticed that most of the cooler mornings (tendency to heat my house more than necessary). Sometimes, it makes the power of Win 7 on screen (Windows 7 and swirling colors, creating a window) and stop somewhere along the way. Other times it cannot even do it in front of the Acer splash screen. Sometimes it will go to full boot (Windows desktop) only to hang. I might have to restart the machine more than a few times to market. However, once I turned it completely, I can turn it off and restart without any problem.

    I reinstall the HARD drive and thought it helped, but only for a bit. The problem comes back. Battery seems to be in good shape.

    One thing I noticed this morning, is that if I unplug the PS, the computer started fine. I still need to do some additional tests to confirm or deny this... but it was a discovery of new and interesting.

    I read in some places that the PS/charger can be a source of such problems.

    Any idea or feedback is greatly appreciated.

    Thank you and see you soon...

    Hi stephr1

    Yes, it sounds as if the charger is at fault. If she starts & runs fine on battery - it's the only thing she could be!

    Buy a replacement charger - one who gives the same output/input as the existing one, then this should solve your problems!

  • Screen of V3 - 772 g Acer problem

    Hello everyone, I encountered a strange problem with my Acer V3 - 772 g. It seems that the screen "flickers" with bars that cross the screen.

    While the majority of the time, it is not visible to the naked eye. In some situations, the problem can be quite apparent and strain in my eyes a little.

    Through the lens of a camera, it becomes completely visible, and comparison with photos and videos I've seen of him I can conclude that it is abnormal defintely.

    I have tried several attempts to solve this problem, as the installation of the latest drivers, the laptop restore factory setting and even the BIOS update. However, none of them seem to have an effect.

    I have, however, found that when the safe boot mode flickering does not occur.

    If anyone can give me any suggestions, I would be very grateful.

    Thank you.

    Hi p1f1313

    Then, it seems to be a bad connection from the motherboard to the screen. Acer support is world-wide, so care must always be able to help.

  • s7 Acer problems

    Hello. I recently bought an acer s7 - 391 and I encounter the following issues:

    1. I have changes in contrast when I slide hollow different applications. for example, when I open the music application, the background looks like it's moving, it wobbles, and the quality of the screen becomes very bad... However, colors appear very high. If I come back at the beginning, the quality begins to seem good again, in about ten seconds. What could be? I've updated the graphics card driver later. nothing.

    2. the trackpad is all bad. When I move the cursor on the diagonal, it is not moving directly, but looks like it's the theater of the waves, some forms of "s". ...

    3. the screen has gray spots in the lower corners. It also loses little light...

    4. my keyboard part 2 shots when I press some keys. I type too slowly and as carefully as I can, but it still doesn't work.

    I think I'll go into service with her. did anyone experienced the same problems that I did?

    Thank you!

    Keep sending/taking it repairs until you get all your problems solved.

  • Automatic detection of G257HLBIDX of Acer problems...

    Hello

    I had the G257HLBIDX monitor mount there. I love very strong monitor.

    But...

    The problem I have is that whenever I restart my computer, the monitor will start to turn channels to find my computer. D sub-> DVI-> HDMI until she reached the connection I use the computer.

    For example if I use D - sub to connect my computer to the screen and I restart the computer, and then search for monitor to the DVI and HDMI connection, then go back to D - sub. Sound very anoing because my computer restarts for 5.7 sec and the monitor take 15 or 20 dry to check all channels. So every time I install the update or something the screen check all channels until she reached the original I put it to.

    Is there a way to upgrade my firmware or something like that so I can put the auto detection function disabled? Sound very anoing

    Lafoza,

    We tested one of our G257HL we have, and it's our findings:

    It scans when there is no computer and it parsed once when followed us in VGA and then switch the HDMI connection. He won't go through the process of scanning again when you are connected to the same HDMI connection, that he recall the entry.

    Are you using any type of separator or box that could be causing to scan?

    If not, and you are using more than one computer connected to this monitor?

  • V nitro vn7 WIFI Acer problems

    I recently bought this laptop and I am very saddened to learn the amount of complaints on wifi problems. I spent a week of downloading new drivers, old drivers, tweak the settings, do what everyone else seems to have tried on Google and I still suffers from problems.

    To summarize, my laptop connects very sporadically to a Wifi hotspot on the medium strength current. It seems to connect well on battery. He yells to me due to lack of design...

    All other devices from laptops, phones to iPads have no question anywhere in the House. I changed the channel and restarted the router etc etc.

    If anyone has any advice please get in touch.

    Currys is the UK, Yes.

    So I got the card Intel 7265 today, Mouser.com, pronounced Texas in 3 days! The problem is no more, the signal is perfect at a distance from the router and is not affected by the mode of delivery and if the load or not. Very happy and a highly recommended update.

  • format micro sd card acer liquid e2 problems

    Hello I have an acer liquid e2 smartphone running on android jelly bean 4.2.1

    recently, I bought a micro sd with a capacity of 32Gbs of kingston card

    at first glance, everything worked fine, but yesterday, I wanted to transfer files via 4Gbs.

    I noticed that it is not possible for FAT based micro sd for this cards but if format you the card micro sd for exFAT, or NTFS you could work around this transferlimit.

    so today, I bought a drive from sd cards to solve the problem.

    I put my micro sd card in a sd card and then the sd card in the sd card reader/writer.

    I connect to my computer and I reformatted my card micro sd, exFAT AND NTFS, but none of them has been recognized by my phone.

    so I searched more on this subject, and it seems that android supports NTFS...

    so I wonder is my e2 liquid acer problem here? and what do I do?

    I hope that I did not purchase this reader/writer for sd cards

    Thanks for the help

    Sorry for the late response

    my phone is rooted so I lack it but there were a few problems update even if it was properly the

    so I changed my phone to its factory settings and updated to 4.2.2

    It was not always able to recognize NTFS in itself, so I searched again and found an app that should be able to do

    the app is called "paragon NTFS and HFS +" it wanted to download it but I need to root my phone to use this application

    so I rooted my phone after update to 4.2.2 and downloaded this app

    now, I'm finally able to use my micro sd NTFS-formatted card

    I don't know if the app alone would be enough to do, but it was clear that I needed the app or at least root

    4.2.2 update alone is not enough

  • Acer Aspire ES 15 wifi issues

    Hi all

    I git a new Acer Es 15 - I upgraded to windows 7 Linux. While I am using wifi key Fn + F3 does not turn.

    I tried all the steps mentioned in this Page. I need some help. Someone please suggest to do.

    Thanks in advance :)

    Hi Nani,

    You can enable or disable your network with a combination of keys on your keyboard, or with a dedicated wireless switch wireless. Acer laptops and netbooks, the following methods are used:

    • A dedicated button located above the keyboard.
    • A rocker switch, located on the front or the side of the unit.
    • The FN and the key with the icon wireless on your keyboard. Usually, the Fn + F3 key combination is used.

    The wireless key can be identified with one of the following icons on or nearby:

    Please consult your user manual on how to enable or disable the networks without wire on your specific model.

    When you turn on the wireless feature, a LED on or near the button or toggle switch turns on or a symbol is displayed on your screen.

    NOTE: On models with the slide switch, the switch itself can return to its original position after the wireless function is enabled. This is normal and does not mean that the wireless feature has been disabled.

    THIS CORRECTS THE PROBLEM?

    If your system may detect the available wireless network, the wireless network is enabled. If you cannot connect to a network, visit the Acer problems with wireless networkknowledge base article.

    Where the combination of keys on the keyboard does not work, please visit section of the knowledge base of Acer keyboard shortcuts does not.

    I would recommend also, install the latest network cards on the Acer support website.

    Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.
