Dell Latitude D520 :: Screen Shrinks To Small Size At Start Up

Mar 23, 2013

I recently formatted my Dell Latitude D520 laptop because of a  frequent shutdown problem.

Also at the same time I have updated my BIOS setup file.

But now whenever i restart laptop, at the start up the DELL logo appears and also the windows logo and other messages appears in very small window rather than full screen size, till the machine gets fully loaded. Once the windows is loaded , it works well with full screen mode.

However,  if i run any Command Prompt application, the screen get shrinks  to small size, the same size which appears when the machine is booting.

On investigation, I found that

a) At every startup in BIOS setup Video/LCD Panel expansion is getting turned off and I have to manually enabled it at every startup

b) If i run any video/audio file the latptop instantly get turned off and may or may not restart for several days. Once it get turned off, it simply start getting turned off at every startup.

I have installed the drivers from the site, but problem persists.

Does it happens because I updated latest BIOS version? Shall i get old BIOS file from dell site?

Dell :: Latitude D520 Keyboard And Trackpad

Jan 11, 2010

My friend is very cheap and will not get a new computer. He has a dell lat. D520. I wiped everything and installed all the drivers from the dell website for the laptop.

Everything works great until you have to type or move the trackpad. It tends to jump around or insert other letters then the one chosen. But a usb external keyboard works fine!

I called dell and said that he doesnt have any warranty and said maybe the buttons were stuck? Should he order a new keyboard for 50 bucks?

Dell Latitude E6500 :: Won't Start Up Past Splash Screen - F8 Won't Work Diagnostics Takes Hours

Jun 19, 2012

I have a Dell Latitude E6500 that I have been using for quite a long time. Recently it started acting up, and now it won't start up past the Dell logo. It simply goes to a black screen with a flashing dash. I've restarted it a few times, tried pushing F8, and gone into F12. I tried the Diagnostics through F12, but it takes an extremely long time and has never finished so far. I tried it again this morning, and periodically throughout the test a message like this has shown up:

Error Code 0123. Msg: Error Code 2000-0123 Msg: Memory - integrity test failed. The given error code and message can be used by Dell Technical Support to diagnose problem. Do you want to continue testing?

Yes or No or Retry

I'm not sure what exactly this means, but it keeps popping up. I would like to get through to start up my computer all the way, but that doesn't seem to be an option. Is there anyway for me to wipe it without F8? My cd slot won't open, and I don't have disks anyways. Is it possible to fix it via USB drives? Or F12?

Dell :: D830 Screen (a Very Small Black Speck)

Feb 1, 2009

I have owned a 10-month-old Latitude D830 (w/1680x1050 screen) for about 8 months now. It's a great machine, but I've decided to sell it in favour of something smaller.

Since I bought it, it has had a very small black speck on the screen that does not wipe away when cleaning it. To me it looks like dust behind the LCD surface rather than a dead pixel .....

HP Envy 15t-j000 Display :: Video Not Working In Graphics Mode - Small Dots All Over Screen

Aug 29, 2014

2 weeks ago I began having video issues on my system. At that time, I was able to get to the login screen and right after I logged in, the screen started blinking at a constant rate (about evey second). To fix this, I booted to the Startup Menu (hit ESC after power on) and got the text based menu. From there I could get to the nice little graphical Windows Startup Options Menus. I used that to do system restore back to July and this seemed to work for a couple weeks.Now when I start the laptop, it quickly goes to a screen full of little dots all over and I can't see anything. I was able to get the text based statup menu that listed (system info, sys diags, ..., Starup menu). But when I tried to get the graphics based menus, it immediately when to the screen with dots so I could not do any of the recovery or start up options (like safe mode).

Attaching screen shot.

Dell :: XPS 1530 Screen Size

Dec 27, 2008

I am considering purchasing an XPS 1530 for both gaming and business use/travel and am having a hard time deciding which screen to purchase? I do play various simulation games and know that the 8600gt gpu is a low/mid level card that would run games and look better at lower native screen resolutions (if not now, then within the next year or two.) I am planning to keep this computer for about 3-4 years. On the other hand, I do like having more information fit unto a screen for web browsing and general typing work.

Should I go with the 1440x900 LCD/LED screen or stay with the lower 1280x800 screen?

Dell :: New Studio 1737 Screen Resolution And Icon/font Size

Mar 3, 2009

had a Dell 1735..screen resolution was perfect and webpages i visited looked nice and sharp etc...purchased a new Dell studio 1737 laptop and it seems that the default setting is 1920 x 1200..this makes everything very sharp but to small to work with...the correct setting for the correct size etc...seems to be 1440 x 900..but when i change the settings to this size everything is the correct size but not as sharp...and websites i visit such as Facebook etc..the text on these pages seems different..now, when I place my old Dell studio 1735 beside my new Dell studio 1737 my old laptop which is set at 1440 x 900..my old laptop looks far sharper and superior to my new laptop! My old 1735 has the highest setting for resolution at 1440 x 900 while the new 1737 seems to have a higher setting option of 1920 x 1200. Is there a big difference between the 1735 and 1737? Am I stuck with just keeping my setting on my new 1737 at 1440 x 900 and putting up with the blurriness etc? Have tried everything from going into Catalyst center to adjusting settings in appearance in vista etc..

HP/Compaq :: Mini Screen Size Change

Jan 15, 2009

I tried a search and couldn't find the answer. Does anybody know why the size of the mini screen changed from 10.2 to 10.1, the resolution dropped slightly because of that too. I bought one in November with the 10.2 and they are sending a replacement with the 10.1, any reason to just keep the 10.2 and repair it.

Purchased Probook 4530S. Win 7. I keep having teh screen print/size resolutiom change when using the touchpad. The pointer seems to "stick" and then when I move it, the screen will either get very smaller or larger. I continually have to hit ctrl + or - to get the screen size back to "normal".

Dell :: Latitude E6400 Won't Start

Mar 21, 2009

I'm trying to switch out the processor of my E6400. When I put the new processor in and start the computer, the lights blink, sometimes the screen turns on (to black), but the BIOS never loads (or even starts). The computer then turns off, and the caps and scroll lock lights turn on, and the num lock light starts blinking.

Does anyone know what that blinking code means, and more importantly, why the computer isn't starting?

Dell Latitude E5520 :: Will Not Start In Docking Station

Aug 10, 2012

We have an unusual problem with a Dell Latitude E5520. It has been built with Windows 7 32bit SP1 and McAfee EndPoint Encryption, as we do with all of our laptops.

When the laptop is powered on and then docked, everything works fine. If you then give the laptop a restart whilst docked, it just doesn't! It shuts down and stays in some kind of power save mode. I have been through all of the Power options, including closing of the lid and turned off everything that could be causing this to happen, but still nothing.

If the power button is pressed whilst docked, the light comes on but that's it, no activity. Undock it, power up, close the lid and dock it again, all of the external screen, keyboard and mouse work as you would expect. I believe all of the drivers are up to date (it is a new laptop).

The docking station is an E-Port Plus DP/N: FFCV6 A00

Dell :: D520 CPU Upgrade

Nov 25, 2009

I would like to upgrade my CPU. I have the base Celeron M 430 @ 1.73 GHz. What other CPU's would just drop right in?

I guess i have the 945GM Family.. (Can accept 4GB Ram)

Also if you have one, for sale that will fit, send me a PM.. Will post a WTB thread once i know what i wtb. lol. I am looking to upgrade to one of the available Intel Core Duo chips..

Would the T2300E @ 1.66GHz or T2400 @ 1.83GHz CPU drop right in to this current system?

If this is correct, then any T2300E @ 1.66GHz or T2400 @ 1.83GHz CPU would work, and compputer brand does not matter, all i am looking for is,
T2300E @ 1.66GHz or T2400 @ 1.83GHz CPU. Correct?

Dell :: D520 Ram Upgrade

Nov 22, 2009

I was just thinking, I only have 1 GB right now. How much do you think of a performance increase would i have if i upgraded to 4GB's. To max it out. Ram is now very cheap.. -

Last time i bought ram, it was $125 for a 512 Chip for the Dell Dimension 2350...

Also, does windows XP read 3.5 or 4 GB? I for some odd reason, i think i remember reading 3.5 Gb would only be used if you installed 4GB in to a Win XP 32 system.

Does this require soldering? Seems like a cheap design or something.

Dell :: D520 Taken Apart + Added A Dust Filter For Fan

Dec 13, 2009

Well, i took my D520 apart to give it a clean... And then it hit me to add a dust filter on the fan so it does not get dusty.

I had a OEM speaker out of my Taurus, and that has this very thin cloth like material covering the speaker for what ever reason

might just look nicer then seeing the speaker) I cut a little square out, and then placed it under the fan. The fan holds the filter nicely, and it does not take away from the cooling

Dell Latitude E6510 :: Will Not Start / Power Light Goes On Briefly / Battery Light Flashes

Oct 24, 2011

I have a Latitude E6510 that will not start.  When pressing the power button, the power light goes on for about 5 seconds and then turns off.  I also notice the battery light flashes a few times when re-connecting the AC adapter.

Removed the battery, held in the power button 30 seconds, but still not working.

We have had this laptop about 6 months.  About a month ago, it exhibited this problem.  After talking to Dell Support, they recommended a system board replacement.  The laptop was sent in and the board was replaced.  When I got it back and tried to start it for the first time, it did the same thing.  I then pressed the Latitude "ON" button, and the laptop started.

Now it is doing the same thing, and I find it hard to believe that another system board is bad.  I am suspicious about this "ON" feature, that maybe the laptop is "stuck" or something trying to get into the "ON" mode.  Or maybe it is just trying to get into "ON" mode. 

I am not sure what the "ON" feature does, but I have noticed a few other posts on the internet of users having the exact same problem.  Again--I find it hard to believe a second system board could be bad.

Arrow keys fully integrated into the keyboard so the bottom 3 arrows don't stick out and none are 1/2 size of regular keysWhite backlights and hinge lights,

which I think represent simplicityFlush screen (plastic cover) that hides the cam light and stuff,

so it seems all integrated and stealthy-lookinI actually like the fact that there is only 1 plate to remove on the bottom of the laptop, makes it seem more organized
