Fluctuations in brightness on E545

• E545 brightness is not setting

  When I opened my laptop E545 after sleeping, I find that the brightness shortcut keys do not work (like other keys, volume, work). Only after the deactivation and reactivation of my graphic card or by restarting the computer entirely, brightness shortcut keys work again. I had a similar problem on an another ThinkPad Edge, E530). That was really annoys me since I computers! I see that there is an update of the BIOS but not sure it will solve my problem (or if it could create other problems worse than uptight brightness). Someone at - he experienced this problem or get it resolved?

  Hi Maisymouser,

  Welcome to Lenovo Community!

  According to the request, we understand that you have a problem with the brightness of the display on your ThinkPad E545.

  Have you checked the graphics driver update & application of Lenovo power manager?

  You can also use the ThinkVantage System Update utility to check the latest drivers and application of your system.

  I hope this helps.

• Brightness fluctuates as the screen changes (watch movies or open windows for example)

  Ive a brand new HP Pavilion 15 and Ive noticed when I opened a window or the screen goes a dark to a light image (for example, while watching the video), brightness adjusts in increments of half the second.

  For example, with a background image dark, I opened a window, I see in the white area of the window, half a second after opening the brightness of "whiteness" is rather dull and increments of bleachers, it becomes clearer and brighter.

  It takes about 3-4 seconds for the light to continue to increase.  I also note, it is not just the window that shines upward, but the lighter areas of the background also brighten at the same pace.

  Its extremely irritating and I can't find the settings to this.  It feels as if the brightness is self-adjustment according to what is on my screen, but I can do myself with the brightness setting!
  I have tried this with the setting of brightness placed as high as possible and at various levels but still seem to get the same result.

  Any help would be appreciated.  Is it a hardware failure?

  Jowelboy, if you're still here, I found a solution...

  If you have the Intel HD graphics card on your laptop, the GUI driver is probably the substitution of all the Windows settings you are trying to change.

  Follow these steps:

  1. Go to the start screen for Windows and search for 'Intel '. Under 'Settings' select "Intel HD Graphics" or Intel Graphics and Media Control Panel"(there are many ways to get to this setting). You can also right click on your desktop and select "Graphics properties", but make sure it has the "Intel" logo next to it.
  2. Once you are in the Intel graphic user interface, go to the power--> battery--> Turn OFF "Display Power Saving Technology." Depending on your driver version, this GUI can vary in appearance, but in the end, you are eager to find and disable "Display Power Saving Technology."
  3. You won't see a difference to what you click on 'Apply', how you will probably notice your screen brighten. It will ask you to confirm. That should solve.

  (I can't take credit for this fix. The nice people at EightForums.com posted a nice tutorial here, but if you're like me, you have tried everything that does not. It is the last step of the tutorial (described above) that it resolved for me. Someone should really sticky this issue as it has been updated a few times in these forums.

• Abrupt brightness and brightness fluctuation

  Hello

  HP 2000-2d28TU PC portable runnig Windows 8.1.

  Having problem with brightness brightness sometimes gets up and down auto.

  Mainly by watching movies.

  Also a few times after that turning on laptop of will point shows high brightness and if I try to lower the brightness it does not show any level of brightness.

  My laptop is under warranty.

  Help, please.

  Thank you

  Thanks for the reply.

  In my view, that the next step performs a refresh of Windows 8. This will not delete personal files or modify the main parameters. This will simply clean the computer completely. This is the next step before reinstalling Windows, essentially and will return to the computer for Windows 8 if it was previously installed. For more information on how to do this, please refer to this Microsoft Web site: How to refresh, reset or restore your PC

• E535 fan speed fluctuates constantly

  I have what I think, this is a common problem with edges: My E535, I got a little more than a week, starts quietly. Then after about 3 minutes the fan will increase to high speed, even under light load (e.g. only Firefox running and limited scrolling or other activity). After a few minutes at high speed stabilized, it starts cycling up and down, upward and down, up and down... This is being moderately annoying. It does this if the unit is plugged in or on battery power. It also happens when I'm doing other things... OpenOffice spreadsheets or word documents or even just letting the system sit idle.

  I tried to change the settings with Power Manager, but for some reason, PM ends up crashing when I try to select a lower fan speed setting and a setting of normal brightness (level 10). The two issues could be related? I assume that similar positions for E530 and other seams it comes associated BIOS. Here's my info:

  MS Windows 7 Home Edition Premium, Version 6.1.7601 SP 1, Build 7601

  Edge E535 model 3260CTO

  AMD A4-4300 M, Radeon HD

  BIOS LENOVO HHET75WW (2.08), 24/10/12

  SM BIOS 2.7

  Thanks in advance for any help. I love the machine, except for this inconvenience!

  No, I simply ran the update http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS029728 utility

  But now the problem is that the CPU fan is too passive. The laptop is very silent but overheating and choking the CPU if you do not limit the frequency of maximum processor which is annoying, but at least less annoying than the fluctuating fan.

  Edit: I should say that it strangles 900 Mhz CPU for demanding applications, when the temperature reaches about 75 ° C until the temperature drops to 50 ° C. Being able to control the fan speed could solve this problem, but apparently you can not on the E535.

• Photos of airPlay on Apple TV look too bright

  Folds in salvation,

  While all the video content crosses very well on my screen of 4 K TV, photos are coming across too bright, no matter what camera I use as a source (iMac, iPhone and iPad). No recommendation for this problem?

  Thank you.

  You have not specified what generation TV you use, but it is not really important. I'm not aware of any solution that allows for "by app" brightness adjustment. The only source that you do not list iCloud photo library, but I doubt it would make a difference.

  You might just find an acceptable compromise, or use one of the TV set pre-series (movies, sports, etc.) to switch to displaying photos.

• Adjust the brightness of the keyboard of the computer instead of the keyboard?

  Yesterday, I spilled some coffee on my keyboard and the computer works well, but my keyboard does not work.  I bought a wireless keyboard to use and it works perfectly, except that the keyboard of my laptop backlight is always on.  I can't figure out how to turn off without using the f5 and f6, keys that don't work on the laptop, so how can I disable this light without using the keyboard?  F5 and f6 don't work on the original keyboard at all, and on the outside, they do not work to adjust the brightness.

  Try this:

  Go to system-> keyboard Preferences, and in the keyboard tab, disable(uncheck) automatically "illuminate the keyboard in the dark.

• Do magsafe pin burn because of the fluctuation of power?

  Hello

  I have end of 2013 Macbook Pro (retina) that I bought in the USA. Now, I use it in India.

  One of the pins of the power adapter 85W Magsafe 2 is burned and glued. It's the tiny pin next to the great.

  Corresponding connector in the laptop also get burned.

  To power the laptop, I attach and detach the magsafe several times to make it work. This is due to

  power fluctuation? The magsafe also get very hot when the laptop support.

  If it's because of the fluctuation of power, I can use "voltage stabilizer" or UPS?

  Please, give me suggestion to solve this problem.

  Thanks in advance,

  Jay

  Voltage stabilizer is always good if you always dirty power.  It causes burning pine? I don't see how unless the connection is not so good PIN-to-pin. Spikes can cause this.

• How to stop or reduce the brightness of the display on a calendar

  Hi people,

  I have a Pro iPad with iOS 9.3.3 which I intend to use for a limit on a store.

  The store is open from 10:00 to 21:00, if of course, I would like to set up the iPad to go to sleep, turn off screen or totally to reduce brightness from 21:00 until 10:00, is it possible?

  I tried the Night Shift option with "Warmer", but it is not really dark.

  Thoughts?

  Thank you

  ... Alex

  Hello... You can do this with the standard IOS. The only thing you can not put any password so that customers can open a release at any time and set the brightness to AUTO.
