When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?
Dell Inspiron 1505 Bios A-14
I'm trying to install Ubuntu on an e6530. I changed a BIOS boot setting from Legacy to UEFI. Now the laptop doesn't even show me a BIOS screen at startup. The screen is backlit, so power is on, but shows nothing. The drive light flickers a few times, but no matter how long I wait, nothing appears.
I can't even switch it back to Legacy because I can't get into the BIOS. Hitting F12 after power on does nothing. Is there some way to get it back to Legacy mode? Or simply reset the BIOS to default settings?
Having an issue with my HP G62 laptop. The computer will power on, but the screen does not turn on, but the power on button light is blinking. The indicator light next to the charging port is red, as is the light next to the wireless button.

View 3 Replies View RelatedThe screen on my wife's presario notebook suddenly went black on sunday. She was surfing on the net when that happened. The screen wasn't completely black, it was kinda gray-ish like the LCD light was still on. The power LED was also still on. She turned the notebook off and back on and the screen stayed pitch black. The power LED comes on, the fan is running and also the DVD drive starts running but neither do I see a picture nor does the HDD LED flicker.
I tried different things like unhooking the power, uninstalling the battery but nothing helped. However after a couple of restarts I was able to make it show the 'Compaq' logo twice. Each time the HDD LED flickered a couple of times and then the screen was gray again.
On the Compaq website they suggest to re-set the RAM module(s). Does that sound like a possible solution to anybody? My wife is going to check if the notebook is still under warranty (She bought it in August last year) before I try to mess with the RAM.
Purchased in 2009 with free upgrade to Win 8.1 Pro. Has been a great computer up to now. On power up, LED's and fan come on but screen is black. Can not see anything behind screen when shining a torch on it. Has worked twice since fault appeared, once on re-boot and once when pressing DEL key. Replaced battery on motherboard and tried combinations of the two RAM boards. Still not working. Have recovery disks, but they are for the old Vista software.
View 2 Replies View RelatedWhen i press the power button laptop seems to be powering up and running but the screen is black. The LEDs for power and disk are on and i can enable the keyboard back light. If i try to turn the laptop on again and again then after some time it boots up ok and then works without any problems, at least until i turn it off. I tried to connect an external monitor but it didn't get any signal.
I'm not sure if it is connected but i think it starded after i did the system recovery. I use Windows 7 Home Premium SP1.
So my trusty old Thinkpad crapped out on me last night. I seem to have no power (adapter works, though) so I think the problem is unrelated to the hard drive and that should be okay. I've decided to replace it with a Macbook. In order to get the files off of my completely dead TP--which I'd prefer NOT to put any more money into at this point--can I turn the HD from the TP into an external hard drive and use bootcamp to boot windows from the (now) external HD, then pull files off it it that way?
Also, I read in the Migration sticky that you have to use Windows XP with SP2 and NOT SP1 with an SP2 upgrade. I think I had XP with SP1 and an SP2 upgrade. Even checking out the Windows site, those full versions all only come with SP1. What's the trick?
should be receiving new key board soon.
View 2 Replies View RelatedI have an ACER Aspire 5542g and i've had a problem with it lately, when I turn it on, the fan starts running, the harddrive turns on, and the CD drive starts up, the power button LED is on, but all that shows up is a black screen. I have tried the "Take out the charger and battery, hold the power button for 30 seconds", tried switching the RAM, tried taking out the harddrive, and all have been a fail. And I am honestly confused, because some of the time (rarely) it will turn on, and literally everything about the laptop is perfectly fine, and its like nothing happened. Until you turn it off.

I here my laptop running but it looks like my screen just stopped working. I wasnt sure what it was so I bought a new battery to see if that was the problem and the screen still does not come on. I had this laptop for about 3 years and thought it was the battery or charger and its not.

View 2 Replies View RelatedI'm working with a HP G72-250US Notebook and using Windows 7 64 bit Intel core(TM). M350@2.27ghz2266 mhz 2 cores
Is it the Mother board or the Harddrive? Replaced screen due to vertical and horizontal lines in color. Computer worked normal at times. I thought it was fixed but then while doing a HP diagnostic program the computer said to shut down because the batttery situation might harm the computer . I tested the AC adapter. I installed a new battery and at first it was working again. I updated and scanned with AVG & Malwarebytes. Did another HP diagnostic and at one point was told to restart. It never lived again to this point.
All it does is light up the power light and W/LAN (F 12). Blue lights are on at times indicating Cap locks and number locks are engaged. I did do a complete factory restore before it came to this point and updated the bios (to F 37) and downloaded updates for chipsets and Graphics also.(after screen installed) The only thing it does now is make noises at startup and power indicator is lit now Light keeps cycling.(light off, light on) in ten second intervals.
HP Mini 210-1000 ... Actually it's HP Mini 210-1060EV PC
From product specifications: Display: 25.6 cm (10.1") Diagonal WSVGA LED HP BrightView Infinity Widescreen Display BID (1024 x 600)
Battery has been dead a long time. My display drivers and BIOS have recently been updated from HP website. After a power failure and a restart, the display looks weird. It was shifted about an inch downwards with a black border at the top, over which the mouse will not go, and the taskbar is not visible as is off the bottom of the screen.
When I go to Screen Resolution from Windows by right clicking on desktop resolution is set as 1024x768, when I click on Advanced Settings, Monitor tab, Monitor is set as Generic Non-PnP Monitor (1024x768 60Hz). When I change to 1024x600 it looks blurry and stretched vertically, but the screen is still shifted downwards with black border on top.
When I enter Intel Graphics Settings I can do the same changes as in the Windows dialog box (640x480, 800x600,1024x600,1024x768).
In the Aspect Ratio Options when I select Fullscreen (No-Border) the Black border is fixed but the screen still appears streched vertically but the screen is cut off at the bottom with no Taskbar visible. Re-installed graphics driver as well as a few Monitor Type Drivers from windows, nothing changes. When I turn the notebook on, the HP Quickweb screen also appears as a 1024x600 stretched vertically with no black border at top but going off the display at the bottom.
It appears that Windows and Hp Quickweb see the display as 1024x768 60Hz after the power failure. Before that, I had installed some Windows Updates but nothing related to Display drivers. I only had a System Restore point from earlier that day (very low free hard drive space?) but that didnt do anything.
Guessing it's a registry/driver problem since no pixels are bad and the black border on top is fixed in Aspect Ratio Options when I select Fullscreen (No-Border).
I have a major problem with my hp pavilion dv6-3143sa laptop.
I put it to a shop and they told me it was a motherboard/cpu problem and they couldn't source parts. I managed to get the parts. I put the motherboard first, but didn't work. I then added the cpu and put on thermal paste, but still didn't work.
My laptop will power on but I'm still getting a blinking light on the caps lock button and a black screen.
I have an Aspire V5-572P-6454. Occasionally I accidentally hit the power button on the side of the computer and it makes my screen go black. I can't figure out how to get me screen back, thought it was a lighting issue and tried Fn and the left and right arrows, but that doesn't work. Usually end up rebooting and losing what I've been working on.
View 1 Replies View RelatedI have an acer aspire v3-571gOn trying to boot up my laptop by pushing the power button, the leds light up and the fan starts ( I can hear it spin) and the laptop starts but the screen remains black and does not even light up. The screen remains pitch black without any change at all.After force-shutdown 12 to 13 times, I rebooted my laptop and the screen suddenly started working.This happened once before as well and I didn't think much of it untill it happened again. I don't understand why the screen randomly chose to black out and not respond until after several restarts.
I tried removing the battery, pressing power button for about 30 seconds, rebooting, starting without battery (with power source) and nothing worked. It randomly and unexpectedly started working (just like it had stopped).
I have a Compaq Presario CQ61 Product: VM9496Q2X Model: CQ61-319WM, that has a black screen when I power up. The wifi button stays red and the caps lock flashes twice. I believe this indicates a BIOS corruption failure. I have tried resetting by unplugging and removing the battery, and holding the power button for 30 seconds. I have tried the f8 key and the esc repeatedly at power up. I have also tried pressing the windows and B key along with the power key but nothing worked.
View 2 Replies View RelatedI had exactly the same problem with my Acer Aspire 5552G with win7, I tried all things that was online e.g. New battery, Flashing bios, Fn + esc without battery when trying to start the computer and so on.
It started now and then and worked perfect but when I shut it down again it could take me up to 50 tries to get it started.
The problem was issues with the boot sector on the hard drive!
Finally I made an Win7 repair disc and started from.
I also checked for errors on the hard drive and it repaired some sectors before starting windows.
After that it works like when it was new. The computer was bought January 2011.
I bought a new Dell Inspiron 15 7000 core i7 with touch display about a week ago. I've noticed that on occasion, especially when running on battery power, the screen flickers slightly.

I have tried to turn on with the power connected but not the battery. I have tried removing the connector cable for the power button and the connector cable for the display and then reseating them.

View 2 Replies View RelatedI have just installed an i7 2670Qm on my T420 today.The machine will crash pretty soon after booting up, with the screen having colorful vertical and horizontal lines before it restarts itself and give the memory error beeping pattern (1 beep-pause-3 beeps-3 beeps-pause-1 beep).So then I took out one RAM from the bottom, and the machine appears to work normally again, more or less.
In the OS (Win7 64), The power manager alerts me that the 65w AC adapter is giving not enough power, so the laptop is running on battery. I thought I just need a 90W AC brick so the laptop will work as it should, so I am arranging a 90w one to come in later. But on a second thought, if the battery cannot start the laptop with 8GB of RAM properly.
Is it the CPU or RAM or Mobo or something else? Where should I look?The machine works fine with the previous CPU i3-2310m and 8GB of RAM.The RAM modules I have are 2 x 4GB Samsung 2Rx8 PC3-12800S-11-11-F3.The BIOS version is updated to the latest 1.46.
