Laptop Blank/Blackscreen Issue

Hello guys.
I have a HP laptop Envy 17 3D. Yesterday As I was using it just browsing the internet, I went to shower when I came back to it about 15 mins later the screen was black you could see the white led but nothing on the screen. I turned it off assuming it jad just frozen when I turned it back on the screen just doesn't show anything not even a light. The led for wifi on the keyboard lights up and the harddrive led is flashing. The motion sensor the laptop has seems to work as the keyboard . lights up when I approach it. I already tried using an HDMI to connect to a tv screem. The TV detects that there is an hdmi plugged to something but nothing displays. I've also tried switching the RAM from different slots. I have no idea how anything could have happened to it while I was showering.
Note: I am NOT able to access anything on the screen including the BIOS.

Laptop blank screen flashing led lights

The HP dv7 laptop blank/black screen with the continuously flashing CapsLk & Num Lock led lights is probably indicative of an overheated graphics processing unit (gpu) on the system/mother board. On the one that I am trying to repair it is an ATI gpu. The gpu is built into the system/mother board.
If laptop gpu is failing then the blinking diagnostic code of the CapsLk & Num lock led lights blinking once would seem to apply. Why even though led lights are flashing continuously? Because the laptop boot tries to load through the gpu via the cpu and fails which thereby triggers the one flashing light then it retries flashing the light again (and again and again continuously). As other posters have commented HP did not seem to care about a design flaw so they hesitate and ignore that fact – they will often tell you that the system/mother board needs replacement. As a matter of record you can see another thread (http://h30434.www3.hp.com/t5/Notebook-Hardware/Blinking-caps-and-num-lock-lights/m-p/29560#M3853) that has 19 pages of posts with over 230,00 views – unfortunately it has been deemed read only by the HP forum now.
I would refrain from an exact duplicate replacement motherboard without proof that the gpu has been corrected on the replacement board. Ebay has a number of replacement system/mother boards that are less than the over $300 price that HP has quoted for the repair. There has even been a listing for an upgraded board that deals specifically with the gpu issue. If the laptop has 17” monitor like the dv7 it may be very well worth replacing the system/mother board.

I have a little more to add
If I turn it on normally, nothing happens on the memory stick (no lights or anything)
If I turn it on while holding down Windows and B, the memory stick turns on after about 15-20 seconds, the light flashes for about 5 seconds then it stops flashing, it just sits on a solid light.
Its almost as if it is searching the memory stick for the files but fails to find them.
I used sp65000.exe to create the recovery stick

My laptop y510p has an issue for the third time and i need a replacement

my y510p laptop got an issue for three times and i need a replacement
i bought it in april/2014 and more than 2 and half months wasted for maintenance.
first time:
after few weeks i got problem with screen colors and i sent the laptop and the problem was in the motherboard and they replaced it.
second time:
i got it from maintenance center with 2 issues:
1- camera wasn't working
2- suddenlly freeze from time to time , sometime a blue screen appear after , i need to turnoff laptop from the power button to work again and it takes so long to open after that.
i sent the laptop again.
note: maintenance center claims that there wasn't any issue and even the camera that they told me that they fixed it they didn't wirte it in report. that's what i figured out when i talked with lenovo customer services
third time:
suddenly freeze from time to time again when i tried to enter bios immediatly after freeze happen i found that
harddisk wasn't appearing.
so i sent it again and i asked for replacement
maintenance replied that it's a motherboard and hardisk issues.
stayed there for 45 days and i called them for like 7 times to know what is the reply on my request and every time they ask me to wait more.
today i called them and they told me that the request of replacement is refused ...!
and they told me to post a message here if i insist on replacement.
laptop serial no:xxxxxxxxx
Mod comment: Removed Serial number for posters security.

It´s crazy how many people have the same kind of problems with this computer.. and what´s even worse is that it seems that the only option is to send it to Lenovo for a motherboard replacement. I have the same problem (mainboard dead) but unluckily for me, my y510p is out of warranty (I only used it for like 4-5 months then it was stored while I was away). Everyday I get on the internet to look for a motherboard replacement myself but I just can´t find any.. Why is that?
Also, this is a "new" computer, if I´m not wrong it was released around the end of 2013. How is it that they already discontinued it? Do they usually discontinue their products that fast? Or is it perhaps all these Y510P computers had problems from production? How can someone spend over a thousand dollars, use the computer for a few months (normal use, not even gaming..) and one day is dead and the motherboard needs replacement?? Why nobody really complains about this? I really don´t know what to do as that were all my money. I really just want to get rid of this crap and never ever buy Lenovo again and never ever recommend it to anyone. I don´t even feel secure spending the money on a motherboard replacement because it seems to me that the problem will come back. Because as I said this seems to be a problem in their production of this particular model. Again, over a thousand dollars computer and its quality is worst than the cheapest ones.. shame on Lenovo.

Safari 8 downloads a blank.html file issue

Hi all...
I am new to web developing in jsp. I am facing a issue that safari 8 downloads automatically a blank.html file. while safari 7 does not has this isssue.
what may be the reason for this ?
should i configure safari settings or coding problem ?
What to do to fix this issue..
thanx in advance

While you can try switching Off Safari - Preferences - Extensions; and clearing data for that sitein Safari - Preferences - Privacy... it's often a problem with the site coding or server, and can't be fixed at your end.
Of course, if this happens everywhere - still try without extensions, and also test in a new or Guest user account.

G550 Laptop Horizontal Lines - Known Issue - On my 2nd After Returning First - Not Feeling Confident

I recently purchased a G550 model laptop -- This laptop has everything I would want in this price range and was pleased to have found it on sale and after a test drive left Fry's Electronics with a smile. When I was walking out, I saw a man bringing back in the same model for a return - I tried my best to ignore that and think positive.
The 2nd day I used it I began to see intermittent white horizontal flicker lines -- sometimes across the majority of screen, always from right to left and then in the very top portion of the screen. It then evolved into a line of white small dashes in the middle of the very top of the screen. Searching the internet, I found many many posts and videos with exactly the same problem or very similar on this same model and others from Lenovo.
I took the time to capture the line flickers with my video camera and decided to return it as it was only used briefly in the 5 days I had it in use. Since the lines were intermittent/random in their appearance times - I had a hard time verifying the defect - luckily the videos and the store manager helped me and offered me a new G550 and extended the return time as if I had bought it on return date (as he should). The man at the return desk actually said "You know you are buying one of our cheaper laptops in the whole store - so what do you expect?" - This was not what I or anybody should hear. If I am spending 300.00 on electronics - it should work as described. I bit my tongue and did not reply as it would not have been a polite response from me.
So now I am running the new G550 that they replaced it with -- funny as certain software is on this one like the Lenovo support software that was NOT on my original purchased laptop.
At the moment, I have app. 10 days left to get a full refund if this machine starts to do the "screen line flickers". However, I am feeling very UNCONFIDENT as I read more and more about this known issue.
Yes, I know the warranty covers this scenario for one year - but nobody wants to ship their laptop back to the manafacturer and wait for repair and or replacement parts.
Is there any known "fixes" for this that will not involve voiding my warranty? --- I understand it is a hardware issue and am watching for the flickers to appear always. Last thing I need -- being on a very low set monthly income - is to lose my 15 day return window and have the flickers appear on day 20.
Can anyone please offer any info/suggestions so that I am not "computing scared" the next 10 days before my return window at Fry's expires?
Shouldnt be feeling nervous after buying new laptops. Other than this issue, I love the feel/size/keyboard and eevrything else on this G550. I dont want it to go bad on me --- but I simply cannot afford to have it turn defective on me 2 weeks from now.
Thanks to all who have read this lengthy post. I would be most grateful to anyone who replies.
Sincerely, FP

hi FA,,
You're issues might be similar to this article - G550 - red, blue, yellow lines appeared on screen.
Sorry to hear about your trouble there at the store. AFAIK, flickering issues / vertical lines are commonly caused by either the LCD cable, lcd inverter, or the LCD itself. Not sure if it's a bad batch but kindly check the solutions that were provided on the article above to see what's the best course of action for the issue.
For the warranty coverage, flickering issues are usually covered if it's caused by a faulty lcd part (the lcd cable, inverter, or the lcd itself), I've seen this happen on my laptop (which is a different brand) and the problem lies with the LCD cable. I recommend you contact lenovo for more info on how to go about having the computer serviced under warranty.
Best regards,
neokenchi

Toshiba laptop hardware NO SOUND issue - I've tried everything!!! PLS help!

I have a Toshiba Satellite tablet laptop Model R25-S3513 model... the sound initially started acting weird, sounding funny like skipping, or fluttering (?) eventually laptop internal speakers stopped working all together.
I bought some head phones, they worked fine via head phone jack on front, for about 6 months... and then that went south too... I bought some external speakers to try on it, they work on my friends laptop, but not mine! Now the volume control won't even appear on screen anymore!
I've un-installed and reinstalled, updated drivers, rolled back the driver, went through the troubleshooting scenarios to no avail... and I am SO frustrated!
I have read that my laptop has an integrated sound card - does this mean I can't replace it?!!
I have read that I can enhance my sound by using a PCMCIA sound card or a USB sound card - but can I really enhance what isn't working in the first place??? What do I need to do here? I appreciate anyone's help at all!
Denise

I have this same issue. U205-s5034. Sound went out after an update to Windows XP. Tried many things, yet nothing worked. So I did a custom install of Windows 7, including all the new drivers. Still no sound. No device in sound Device Manager either.
Is it possible the integrated sound has died? I have tried installing the drivers in many ways, including from safe mode. Same results always. Just a speaker with an X and the note that there is no audio device.
Is it possible to replace just the sound hardware or is the fact that it is integrated mean I must replace the motherboard? I understand I could purchase a sound card? Any suggestions?

This MacBook Pro (circa 2011) is the second Apple laptop I have owned with the exact same issue. When I change sites (or at least many of them), the Mac issues a single chime. I do not have any clue what this might be ... or if it even needs repairing if I can stand the chime.
If anyone has any ideas, I surely would love to hear! Many thanks!

Adding new site columns to my issue tracking List, will result in having their Source field as blank inside the Issue content type

I have added an Issue tracking list to my SharePoint team site 2013. Then I wanted to add 5 extra columns to my list . So I did the following:-
I went to site settings.
Then I added 5 new site columns.
I went back to my list setting, I click on the “Issue” content type, and I added the 5 newly added site columns to my "Issue" content type , using the “Add from existing site or list columns” link as follow:-
And then these columns were added automatically inside the Edit, Create& Display forms.
But since this is the first time I work on such a task , so I want to make sure that I did every thing correctly. Because I am not sure why the 5 newly added site columns will have their source field inside the “Issue” content type as blank , as shown in
the above picture. So does this indicate that there is a problem ? or this is because I have added the 5 newly added site columns to the List content type and not inside the Content type at the site level ?
Thanks

Hi,
It’s by design, the Source field means the content type name.
As you said, when we create a new column, if we not attach the column to a content type, then the column would have not the source field option.
However, if you create a new column, then add the column in a content type, the content type would automatically update in the site.
Now, you would see a source content type appear.
Thanks & Regards,
Jason

Greyed out images; exports to Mail are blank; generating images issue

Selected images are greyed out in the main viewer; sending a reduced file size via Mail gives a blank mail, but with a selectable rectangle and correct file name with a size only around 25kb. Sending originals at 100% works OK. The generation of reduced size images seems to be causing the problem as I can view an image at 100% in the main viewing area. Exports seem to still work OK - again 100%.
I have deleted the prefs file. I have deleted the application, although reinstallation seems simply to un-delete, returning the app to 'as was'. I'm hopeful that reinstalling will cure this, but how does one remove the application completely?

I got another great answer from yahoo.
They told me to clear cookies, cache, etc...
They said to reboot.
They said to try opera.
It seems no one reads my emails there to support nor do they do proper troubeshooting.
I am in the IT field and I appreciate good support when I get it but unfortunately it's so rare.
The first thing they should be doing is trying to either replicate the issue or verify whether yahoo did any updates on their end.
Instead I'm being sent ridulous help links because they can't even read.
I've sent all information necessary from screenshots to os to devices.
Personally I believe yahoo made an update that's screwing everything up.
Not only have I done those things they suggested but I told them twice already.
The only thing I havent tried was opera. I tried 4 different browsers and none worked.
I tried opera just to shut them up and it didn't work either. It seems opera handles mobile mail differently than all the other browsers as they show no pictures at all. They aren't missing, they just arent there with how opera handles the mail. They instead give you a link to view the store advertisements.
I think I need to call them and see how far up the chain I can get with someone who can actually read and even troubleshoot.

Blank popup window issue

Hi,
In my application, I have an ALV in which one of the columns is a link to another ALV in a popup window. If the link is clicked for the first time, the window pops up with all the values as expected. But, if the link is clicked for the second time (any link in the first ALV), I get a blank window as a popup. This time the popup contains all the UI elements except for the view container UI element (ALV). I also created other simple test programs but still face the same issue.
This is happening only in the BW system. The same is not the case in any other development system (confirmed by developing sample programs).
Please help me out to resolve the issue.
Thanks,
Gokul

I am not sure if the below link can help you, but see if it gives any input to you.

Blank Grey Screen Issue

Hi,
I tried to upgrade to Yosemite last night and I think there's something wrong.
At the last step process gets to a grey screen with Apple Logo with a filling bar below it. As soon as the bar hits quarter way everything disappears and I'm left with a blank grey screen...
I don't have much on this iMac few folders and pictures.
Anyone experiencing the same issue? Any advice?

I just tried to install 10.10.1 and ran into the same problem, however, in my case, I found that the login form disappeared (invisible). If you're able to move the mouse pointer, try moving it around the middle of the screen where the username and password text fields are supposed to be. If you see two places where mouse pointer turn into a keyboard prompt, type your user name in the upper one and your password in the lower one and hit the return key. You should be able to complete the installation.

HP DV9000 Laptop Instant Shutdown Battery Issue

Hello everyone,
I'm new here and I am having some laptop issues and was hoping someone might be able to assist me with them. First I would like to list my computer specs:
HP DV9543CL laptop
Intel Core 2 Duo T7300 2GHZ
2x 160 GB SATA HDs
2 GB RAM
Running: Windows 7 x64
Below is a rundown of what is happening and what I have done to try and resolve my issue:
My laptop was making some retched loud noises from the fan and it wouldn’t stop or slow down at all, it would just stay on with its highest RPMs. With my warranty expired, I decided I would open up my laptop to try and clean out the fan and heatsink. I have worked on and built my own desktops for a while and I decided that I should be able to clean the laptop fan (a decision I currently regret). I got everything open and took everything apart and cleaned out the fan and as I was putting the laptop together I had a hard time putting in the flat cable for the HP Quickplay Switch Board and slightly damaged it. After everything was put back together, I fired up the computer and everything booted up properly. I noticed that the HP Quickplay buttons lights still came on, but the volume slider lights were no longer illuminated. The Quickplay buttons no longer work (which I can deal with because they illuminate properly) but I am having a bigger issue now.
I noticed when I booted up Windows, my battery icon showed that my battery was charging but when I hovered over the icon it said my battery had 0% but was plugged in and charging, however the percentage would never increase indicating it was actually charging. I thought this was weird so I decided to unplug the laptop from the AC adapter to see what would happen. When I did this, the computer stayed on but still told me that the battery had 0%. I decided to leave it that way (since I knew the battery had an almost complete charge) and check to make sure everything else worked. After about 5 minutes or so, my computer shut down instantaneously (like if you were to pull the plug without the battery in.) Knowing this was a bad sign, I decided to try and figure out what was going on. I tried plugging in the computer with the battery in and after about 10 minutes or so the computer shut down the same way. Next I thought I would try using the laptop without the battery in and use it on just AC power. This seemed to work and since I have been using the laptop this way, it has been running alright. My wife has the same exact laptop so I thought I would check my battery in her computer and her battery in mine because her computer is running fine, and, of course, her battery does the same thing in my computer and my battery reads just fine in her computer. So I am now resorting to working on my laptop only on AC power, but I’m sure you can understand my frustration in using a laptop this way. I also thought maybe it was a software issue in my Windows OS so I loaded up a Ubuntu live boot environment and found that Ubuntu was reporting the same battery issues as Windows (saying the battery was charging at 0% but not increasing in charge and reporting that the battery was empty when off of AC power but still running for a short time.)
There is one other issue that is happening. If I leave the computer on with the battery in (with or without AC power) and leave it sitting, eventually the battery charging indicator light starts flashing as if something is wrong. This also happened when I had the computer completely off but left the AC adapter plugged in with the battery in (as if to charge the battery). This led me to believe that the issue is a hardware issue but I had to check to make sure it wasn’t an OS problem as well.
I really have no idea what I could have done to the computer to have this happen. I checked everything that I did when disassembling the computer and I didn’t tinker with the battery or anything that controls it, to my knowledge. If anyone has any ideas or suggestions it would be greatly appreciated. I really regret ever opening up my laptop but now that it’s in the past, I’m hoping I may be able to at least fix what I’ve messed up.
Sorry for such a long post and thank you, in advance, for helping me with my issue. Let me know if there is any other information you may need to assist. Thank you for your time.

So I just had another shutdown but this time it was without the battery in and on AC power (which was working fine before). I decided I would load up World of Warcraft to play, since I thought it was working, and after about 5 or 10 minutes of playing the computer shut down. It doesn't restart when these shutdowns happen it just goes off and stays off. I have been monitoring temperatures to see if that could be a potential issue of overheating (although I still think there is a battery problem too) and found that just random web browsing has the computer idle around 44-45 C and when I am running World of Warcraft it was ~80 C. I don't know what normal laptop temps are but it didn't seem overly stressing but I don't know. It's working for normal web browsing and word processing but World of Warcraft is too stressing apparently. Any insight anyone has on this issue would be wonderful. Thanks for your time.
