HT3964 Backlit keyboard: some keys are brighter than others. Can this be fixed?

I spilled a small amount of liquid on the key board, but I quickly dried it and everything works fine except the keyboard. Some keys are brighter than others, what should I do?

Hope that it is the only problem that you will have with your MBP. Liquids have a habit of quickly migrating and you may or may not have gotten it all. I would take it to an Apple genius bar and have them check it out. That does not mean that your MBP will not suffer a premature death.
As far as the keyboard is concerned, pose that question to the genius bar technician.. I suspect you will be told that the only way to rectify the problem is to install a new one.
Ciao.

ITunes play counts are wrong. How can this be fixed?

I like managining my play counts, since I use a couple of smart playlists based on playcounts. However, I have this issue that I can't honestly seem to find a resolution to online. I see users with this problem, but no resolutions. Whenever I have to sync my iphone to itunes, it ends up jumbling up my play counts for some reason.
Example: If I have song A, that I've played 5 times previously. I play it 3 times, then sync my iphone, it'd end up with 13 plays (5 plays previous, then 5 plays again, plus the three extra plays.) I'll have song B, with 0 plays. I play it twice, sync again, and get 0 plays for the song.
Can this be fixed? I want song A to have 8 plays in iTunes/iphone, and song B to have 2 plays. This does not make any sense. I'm confused. I've heard it started with iTunes 8, but I can't downgrade since my iphone is on the latest firmware.

What should be happening is that each time you sync the device the number of plays made on the device since the last sync are added into iTunes as a global record. This system should be able to accurately support multiple devices. Because smart playlists can use play count as a parameter the devices must record both the current "total" and "device" play counts.
The first suggested fix for anything a bit random like this is to restore the device in the hope that it will just go away.

Capacitive keys are brighter than normal after Den...

I have seen this issue posted several times on the WPC forums. Is there any solution.
Below is a copy and paste from their fourms.
Hey fellas. Just received the Long awaited denim update, with the flagship perks of course. But there something else im noticing. The capacitive keys at the bottom are much brighter than before denim. Now it maybe something in my eyes, or I just never noticed how bright they were...but I'm sure that before denim, the lights weren't that noticeable.Which is pretty distracting to be honest, cuz it doesn't help you to focus well on the screen. Anyone else feeling this? Any solution?
My ATT 1520 has this issue.

funny you bring this up. my 1520 is seemingly the same as well.
noticed that I could see the light where the buttons are located through the back of the red case in the dark last night.
I cannot see that there is anything we can do about it, and am not sure what or why it has even come up.

Some albums are quieter than others

This has just happened in recent. I've never had problems with volume, but strangely some albums are losing volume. They used to be loud, but now the volume is down for them. Some albums volume has stayed the same, but others are becoming more quiet. I tried closing the apps, turning my iPad off and on. is anyone else experiencing volume loss with their music?

Nevermind. I was stupid and forgot I switched on soundcheck. Fixed it

Comb field - some combs are darker than others

I'm having problems creating text fields that have combs. Some of the combs appear with darker border lines than others. How do I resolve this issue?

Thank you both. I think I have resolved the issue with your advice. Each page has a logo on, and some have transparency. I can flatten these and it seems to work!
Thank you!

SharePoint 2013 Error Exception from HRESULT: 0x80131904 Some sites are working while others give this error

I can access some of the sites, but others are throwing this error code... not sure why it appears that it is every other site almost...
I can actually get this error, at a top level site, go to a sub-site and that site is displayed.
Any ideas on how to resolve this error..
the Central Admin site is down also, just a blank page is returned. no error message...
we were able to add extra space on the VM brought back the sites but now the Central Admin site throws a 404 not found...

Hi ,
According to your description, my understanding is that after adding extra space on the SQL server VM, the error 0x80131904 disappeared, but the CA got 404 error. Is it right?
Afer adding extra space on SQL server, make sure the SQL server is online and run SharePoint 2013 Products Configuration Wizards, when running, select “don’t disconnect from the server farm”.
Check whether this issue occurred on other machines. If CA is working from other computer and only server is facing this issue then you need to create diableloopbackcheck registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa. The value should
be 1 .
Please go to IIS->the server->ISAPI and CGI Restrictions, check whether there are four 'Microsoft SharePoint Foundation 2010' entries. If not, you need to create the following entries with the name as 'Microsoft SharePoint Foundation 2010':
                 C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\isapi\_vti_aut\author.dll
                 C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\isapi\_vti_adm\admin.dll
                 C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\isapi\shtml.dll
                 C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\isapi\owssvr.dll
Check Allow extension path of execute to allow the restriction to run automatically.
If this issue still exists, please check the log file to find more information about this issue. The path of the log file is : C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS.
Or you can use Event Viewer(Start->Run->event viewer) to find the log.
I hope this helps.
Thanks,

Some songs are louder then others, can I balance the volume?

Windows XP Pro
My nano plays songs at different volumes for some reason, I have to constantly adjust the volume level. is there a way for itunes, or ipod to level the volume?

Hello rhufnagel,
I am pleased that you have found the dicussion forums tailored specifically to your product.
In regards to your inquiry about your iPod Nano playing songs at different volumes, yes it is possible to have your songs play at relatively close volumes. Here's how:
1) Go to the Main screen on your iPod. To ensure you are at the correct screen, press the "Menu" button on the ClickWheel. If the screen menu's do not change, you are on the right screen.
2)Select "Settings." Find the Sound Check option. Highlight it and press the Select button. Make sure that Sound Check it is enabled.
This should solve your problem. If it doesn't, please don't hesitate to post again with further inquiries.

My browser has been infected with a virus that is not showing up in a scan. When I do a Google search and click on the desired site, I am diverted to some completely unrelated commercial site. Can this be fixed? in English

In Firefox I did a search for Alaksen ( wildlife refuge). The search results were appropriate. Clicking on any site in the Google search diverted me to various commercial websites that were completely unrelated to Alaksen.

Try running several malware scanners. It is best to run several as each will pick up things that the others miss. Some scanners you can try are:
* Malwarebytes - http://www.malwarebytes.org/mbam.php
* SuperAntiSpyware - http://www.superantispyware.com/
* Ad-Aware - http://www.lavasoft.com/products/ad_aware_free.php
* Windows Defender - http://www.microsoft.com/windows/products/winfamily/defender/default.mspx
* Spybot S&D - http://www.safer-networking.org/en/home/index.html
This link may also be of use - http://deletemalware.blogspot.com/2010/02/remove-google-redirect-virus.html
If the above malware scanners do not find any malware or can not clear it, you should consider posting in one of these forums for specialized malware removal help:

Yesterday, it was working perfectly, I properly shut is down. I have set a BIOS pasword.
Today, when I switch it on, I was unable to type the pasword becasu some keys were not working. However, I managed to loged in with the help of On Screen Keyboard. After analysing it, I came to know that some keys on numpad includeing 0,2 and on the 2nd line(vertical numerical keys) 1,2,3,4,7,8,9,0 are not working. I tried to re-install the OS but I set a BIOS paswoed containing one of the missing keys.

Some keys are not working

I have HP pavilion notebook PC with product number F6C53PA#ACJ serial number [Personal Information Removed] BIOS F.34-10/31/2013 keyboard revision 29.34.
Some keys in my keyboard are not working properly. I couldn't type < and > in microsoft office, on the websites etc.

I understand that some keys are not working on your keyboard. I am happy to help with this. Are those keys working consistently in some applications?
