The monitor on this is an LCD, not an LED monitor. The symptoms you are describing are classic fluorescent backlight failure symptoms. It seems a bit early in life for that to occur, as most failure after 2-3 years of use. To determine if the backlight has failed, after booting the system, look at the screen at very close range at an angle. If you can see what looks like a ghost image of what should be on the display, then the video chip is providing video to the display, but the backlight isn't illuminating it. Repair or replace the monitor.
no need. because the on board vga pin won't work after inserting a graphics card. if you want to connect more monitors, you better buy a vga-splitter (1 into 2, 1 into 4, 1 into 10 . . . )
With the Desktop being an all in one it is doubtful it has video output features. If it did you could always hook the Computer up to the TV directly with cables. However, the other option is to stream the video from the PC to your TV with something like this.http://www.newegg.com/Product/Product.aspx?Item=N82E16822136997&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-Video+Devices+%26+TV+Tuners-_-N82E16822136997&gclid=CJaX75mu8LQCFSemPAodcT8ASw
If the graphics card has only a single video connection then it is not possible to add a second monitor.If it has two video connectors the you can add a second monitor otherwise you need to replace the existing video card with one that supports dual monitors..
Question edited for clarity and toss in a few CAPS.
Question moved to Acer Aspire category.
There a few issues that can cause this, the obvious one is that the battery has failed internally, but it can also be a charging software issue. Try this. Unplug from the mains supply. Remove the battery. Leave the computer for 2 hours. Press and hold the power button for a full 2 minutes. Replace the battery, plug back in, count to 10 and power it back up.
Has the motherboard battery ever been changed? They are critical to the health of the motherboard and the machine in general.
If you have no internal hard drive installed you won't get it to work correctly as the hard drive is where the data is stored for the operating system.
OucH no acer real model PC told at all wow hard nut to crack that, I sure can not guess that ...The case told only helps if power on button is wrongor the PSU is wrong. I moved this to acer forum. as the mobo matters.Q1;never worked before by you,? this acer mobo by you?or found it used and dead.? used mobo come good bad or a wreck. (history not told , as in when did fail)the acer.com is the place to look first. for manuals. not told what GPU are you using onboard vga or GPU card or what?All fans spin ? CPU and PSU????if using GPU card that has fan, does it spin too??if case fans do they spin?DoeS DVD tray eject (button hit)?DOES PC beep or flash LED codes?Q2;What VIDEO port class is this "connection"is it:vga, hdmi, dvi or DP ports which one, and where is it? For now only use (if has one) use the VGA port on the mobo , no PCI cards in slots., NO HDD, AND NO DVD DRIVE (JUST UNPLUG THEM FOR NOW) ALL USB THINGS UNPLUG, KEYBOARD LEAVE THERE.MEMORY :pUT 1 stick of ddr RAM only in bank0 channel "A"CPU socket pins bent as seen on ebay endless and sad. below is me guessing what Acer you have.and find this, Acer/GATEWAY ZX4951 or ASPIRE Z3100I read the GW manual check jumpers.the PSU needs 2 power cables to the mobo.4pin power and 24pin (or 20 on legacy)or mobo will be dead. why mess with ACER. (they have no service manuals)put an Asus or Gigabyte mobo there and end this ACER pain,post a photo of the mobo and we can guess what PC it came out of, .......
mute the speakers if still sounds noisy the fan inside is packed in lint and needs to be cleaned out or overeheating is bad news.
why not ask a shop to look into this.
we can take it apart (covers ) and user or stethoscope to hear noise.
a $5 tool that is. and all shops have one or DIY one.
I put my hear to hDD casings me,
i use tube and put it near the fan vent to hear it scream.
there is no other way besides unplugging all that 1 by one to hear it go silent.
this is SOP, vast PC's pack up in lint and fail.
