T510 FHD screen--trying to max the brightness outside.

i love thinkpad's matte screen--very little glare. However, i use it outside a lot in sunshine, so need it to be really bright enough to see. The FHD is bright, but want it a bit brighter. i've tried all the windows and lenovo settings and gotten it as bright as it can go. i also upped the brightness in the Intel HD control panel, in the color settings. However, i see that, in the screen resolution settings, under advanced settings/color management/advanced, lenovo lets you change the device profile from the system default (sRGB IEC61966-2.1) to Lenovo Thinkpad MaxBright Display. is that something i should stay away from for some reason? is it maybe analogous to the old "overclocking" concepts?
thx,
jeff

Hi Having Trouble,
Thanks for visiting Apple Support Communities.
If the brightness on your MacBook Pro isn't adjusting as expected, try resetting the computer's PRAM first. This step can help with many display-related issues.
About NVRAM and PRAM
http://support.apple.com/kb/HT1379
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information.
Best,
Jeremy

I am trying to use the brightness adjustment on a grayscale photoshop CS6 file. The preview shows the adjustment working and changes the brightness, but when you click to apply the change, it does not apply the adjustment. I have run into this problem before, although rarely, with some other files over the years and with earlier versions of CS. I would like to know how to overcome this problem?

Make sure you are viewing your image at 100%. At smaller views, pixels and layers and the way they interact are approximate interpolations and won't show you the actual pixel-for-pixel changes.

I have a "white screen " ,tried to hold the two buttons down and it still won't work.The screen goes dark, then comes back white.

Take a look at the Will not turn on, will not turn on unless connected to power, or unexpected power off section.
Have a nice day,

The screen of my imac always goes to the maximum exposure. Then the light icon on the screen. After reducing the brightness goes my screen after a few minutes back to the maximum intensity with the brightness icon back on my TV screen.

Try resetting the SMC and if that doesn't work then reset the PRAM too.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET

I was not using my Iphone for some time and when i charged it for use the screen is not lighting up. the image is very dim . Please assist to correct this situation., I tried to increase the brightness.no use.

Iphone 3 GS was not being used for some time. When I charged it for use the screen is not becomeing bright. The images are very dim although i increased the brightness. Pls assist.

Since it's a new machine, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine. That also might apply to newly bought ones inside the first 90 days.
FWIW, IMO, the AppleCare extended plan's the cheapest insurance you can get for your new desktop machine.

My screen gets dim and the brightness control buttons don't work

My screen is frequently dim. The brightness control buttons display that they are working, but the brightness doesn't actually change. Any ideas why and what I can do?

Thanks for the suggestion. Actually, I had tried that but still had to go into preferences any time I wanted it brighter. After I posted, I found a thread using some different keywords and found that people were having the same problem with OS versions up to 10.7.2 but solved it with the latest update (10.7.3). I just installed it and now seem to be able to adjust the brightness with my keyboard no problem. I appreciate your reply anyway!

My iphone 4s' screen is shaking when the brightness is in maximum

My iphone 4s' screen starts shaking on the upper and lower part if I adjust the brightness on its maximum level (which I rarely do), but it still bothers me that there's something wrong with my phone. I usually set the brightness on medium level just enough to see the screen clearly. I'm here in the Philippines and I bought my phone last year in California. We don't have a genius bar over here and Mac stores doesn't offer repair services unless your phone is bought from a carrier (AT&T or Verizon over the US). The warranty of my phone expired two weeks ago I've already restarted and restored my phone but nothing's changed. I don't have any idea of the problem is with the LCD screen.

My iPhone 4s screen is cracked (due to being dropped) and I can't slide to unlock it. Several of the the icons on screen will not work either. Is there a way to recover my photos if the phone has never had a back up and never been synced with another device?
No in order to backup to iTunes, you would need to unlock your phone.
In order to import pics to your computer you would need to unlock your phone.

My sister damaged my iphone 4s it while it was at her home. but the screen looked as if it had been drowned in water. it came on for about an hour then i tried to change the brightness to low and the screen went out comes up on my pc, no screen light up.

I was wondering what can be done to fix my iphone i love the poor device and refuse to use any other phone. the screen does not light up at all and idk what is the problem but it connects to itunes and comes up on my laptop with all the contents listed when connected with usb just no screen activity help please

There are many ways to back up photos and contacts on an iPhone:
Photos - copy them to your computer with a USB cable; the phone will appear in Windows or Mac as a digital camera.
Photos - Enable Photo Stream, which saves them to iCloud and syncs to your computers(s)
Contacts - set to sync to any contact app on your computer (e.g., Outlook, Address Book)
Contacts - Enable sync to iCloud. This is real time and will always be up to date
Everything on the phone (including contacts and photos) - Back up to iTunes on your computer
Everything on the phone - Back up to iCloud
All of these are described in the manual.
If you did not do ANY of these then the contents are already lost.

Anyone have photo/photos of T510 FHD screen in Win 7? Curious how it looks.

Finger on the order button, only choice left is FHD or HD... no experience with either. Ugh.
Solved!
Go to Solution.

the FHD on the W510 and the T510 should have the same spec. The above picture is a W510 with FHD.
HD+ is ok, but i will avoid HD one if you are going to do photoshop stuffs.

Has anyone experienced the on/off touch button and the brightness touch buttons failing on a 30" cinema screen?

I have a 30" cinema display which is about 3 years old. Everything was working fine yesterday but on reboot today the screen went dim and the brightness buttons did not work. I used the key board and increased the brightness but it went dim again on release. The on/off touch button also did not work.
I have set to disable both of these in the preferences and all is working now but I wondered if anyone else has experience of both of these touch buttons failing. The monitor has been switched off when booting up on a morning but I had not switched it off manually before shut down or set it to do so which I thought was odd. Now I wonder if it was the first signs of a breakdown of the switches on the monitor.
Thanks for any imput in advance.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Adjusting the brightness of G4 400 TiPB doesnt work

Hi folks,
my Boss´G4 400 Titanium Powerbook recently showed a problem with the F1/F2 Keys. Pressing F1/F2 has no effect - the brightness of the display cant be changed anymore although the other controls, i.e. Volume via F3/F4/F5 work normally. Also the screensigns which appear in the middle of the screen when you change the brightness dont appear anymore, which is unlike other related problems posted here before. The screen itself looks like the brightness is adjusted to a rather dim setting or around a middle setting (kinda hard to tell when you cant change it). Searching other related topics, I found hints that this may be a TiPB related (and known?) issue but I couldnt nail it to the exact issue. After updating to Tiger and then to 10.4.2 the problem didnt show up at first (he updated just after Tiger´s release), everything worked fine until yesterday. Anyone got a clue to what caused this and maybe how to fix it?
Thank you in Advance
Dennis

I am experiencing the same problem on my TiPB 400: very dim display, brightness controls on keyboard don't work and don't generate the screen icons, no brightness adjustment slider in the display system preferences panel, as it should be (and was). I went through the usual resets (hardware reset button, PRAM, open firmware).
I occurred just about two days ago, right about after the most recent security and Quicktime update.
I am running 10.4.6 and have been since it became available, without seeing this problem.
Given the fact that there are distinct features missing from the software (icons and control slider), I am not so certain whether this is just a bad inverter. Or is OS X this smart?
Another problem, which may or may not be related:
Just a bit sooner, my airport connection started to fail. I have several computers connected to the same network (typing right now from a !2"PB), so I know it's not the network. I also have an external AriaExtreme wireless card that is also unable to connect, so it is again somewhat less likely to be a hardware failure. This card is recognized by software, but the airport software doesn't seem to be able to control it anymore as it used to do just last week.
Any suggestions?

TS4494 I tried this but still the brightness of my Macbook 17" i7 is grey. I am not getting full sharp bright screen which I was getting in Windows 7 before.

I am using MacBook Pro 17" i7. I just installed Windows 8 on it. I installed latest version of Bootcamp. Somehow the brightness of screen is not fully bright. F1 and F2 does work but does not give me shiny bright. I tried Windows Setting->Brightness but the level is on top and still have grey brightness.
Do you think Apple Store can help me If I take my MacBook to them?

When I went to adjust the brightness on my phone, the screen went black. I have tried everything...resetting, turning off/on, charging, and restoring. I can see the "unlock" page and the "passcode" page, but when I enter the passcode, it goes dark again

When I went to adjust the brightness on my iphone, the screen went black. I have tried everything I can think of and have read online to try....resetting the phone, turning it off/on, charging the phone, and restoring the phone. I can see the "slide to unlock" page and the "enter passcode" page. When I enter the passcode, the screen goes dark again. I can't even answer calls. What should I do now?

If no change after restoring the iPhone as a new iPhone or not from the backup, the iPhone has a hardware problem.

T510 FHD display not bright enough

i prefer lenovo's matte finish screens--very little glare--great for business purposes. However, i use the laptop outside a lot and therefore need the brightest possible display, for use in sunlight, where primarily i'm using outlook and Word. In Feb 2010, i bought a T510 with the FHD (270nit; 95% gamut) screen, and it was perfect for outside--very bright and easy to see.
then my laptop was stolen! Insurance bought me a new one--same exact T510 (only with outlook 2010 instead of 2007) with same FHD screen. Problem is that it's definitely not as bright. i turned up brightness in windows and in thinkadvantage. also maxed out brightness in the NVidia control panel (which did nothing, since that's really for video playback), and i even have played with the color-saturation brightness and other levels in the intel HD control panel (which increased the display somewhat, but still not as bright as my previous T510--also tends to wash out the colors and makes outlook a bit harder to read).
also weird: about once a day, on battery, the display dims almost to darkness, then gradually brightens back up in about 20 seconds. i'm using max performance on all battery settings, so don't why this is happening. not a big deal, but i thought it might be connected to the above problem.
i talked to lenovo warranty/service tech, who had no other ideas, other than to return the unit--which i don't want to do, as i've now got this one all set up.
any suggestions, folks?
much thanks,
jeff

In the text you say you are using Snow Leopard. Snow Leopard will not operate on a G4 (or any Mac with a PowerPC processor). Leopard OS 10.5 is the max OS for PowerPC processor Macs. Your profile shows OS 10.5.6. What OS are you using (or trying to use)?
Will the PB boot using a systen install DVD?
