The "No Signal" warning indicates it is not receiving video from the "compute" compontent of the device..

Given it's an all-in-one device, you'll have to likely crack the computer open to see if there's any loose cables between the mainboard and the display. Here are a couple video describing disassembling these types of devices:

Acer Aspire Z5801 All In One Disassemble Repair

If there are no cables between the computer portion and the display, then you're out of luck.

Dear f1at3r1c

Righteo then, you should be starting by resetting your BIOS, and you can do this by removing the outer casing o the PC tower. Once yoiu have done this you then need to find the jumper that clears the CMOS/ BIOS. Now if you are somewhat unsure of what a jumper switch is, it just consists of a smallplatic cap which covers two metal conductive pins on the motherboard. There is usually a pin which is not covered.

Now once you have found the CMOS/ BIOS jumper setting, you will need to first remove the motherboard battery. The battery is nothing more than a glorified watch battery of the CR2032 type, and it will be silver in colour and obviously round in shape (typical cell battery).

Once you have removed the battery, you will need to then clear the CMOS/ BIOS and this is done by moving that jumper switch into the clear position. The pin that is exposed will need to be covered withthe plastic jumper, and the pin on the opposite side will need to be exposed. Leave the jumper in the clear position for about 10-20 seconds or so, and then replace it back to the original position. (doing this discharges all of the electricity in the BIOS/ CMOS chip). Once you have done this, you put the battery back in place and then start the machine, then you are good to go. Start the machine and enter the BIOS as you planned to do. You might want to consider ormatting your hard disk and re-installing windows or whatever operating system you have, and this is eeasy enough, just change the boot sequence to boot from your CD/ DVD drive first, the your hard drive second. Once its loaded up, re-enter the BIOS and reset it back to HDD first.

Now f this has not worked, then you have an oooopsie (this is my saying of oh ***T, oops, something has malfunctioned. Its more than likely to be hardware driven, so take out your hard drive first and try to boot, if it lets you bios, then you found your fault. Try this with all devices until you either find the fault, or you have narrowed this to your processor/ motherboard.


Now im sure this will solve your problem, but there is one thng you should need to know about, and it is how to identify the correct jumper. This will have either any of the following markings written on the motherboard very close to the where the jumper is. You may need glasses/ magnifyer lens in order to read the lettering, but it should say one of the following things.

CLRCMOS
CLCMOS
CLRBIOS
CMOSRST
RESET
CMOSRT
BIOSRST
CMOSCLR
CLEAR
could also be under J1, JUMPER1

Now im sure that this is the fixya for you, but if this still does not work, then please get hold of me, and i will provide you with more info.

I wish you all the best, and hope you manage to solve this issue sortly

kind regards

yours sincerely

This is THE single most common problem with the Acer Aspire L100. Initially really happy with it, but then after five months, mine started freezing and then refusing to boot. Since then it's been very tetchy so I just bought a new computer. The problem lies in the design, it's TOO small to allow adequate ventilation to all the components - something Acer should have figured out before selling the machine. If you can boot your machine up to bios, go into it and change the temperature settings so it runs the fan at full blast. This may help, but I cant garantee it, sorry! If your warranty is valid, demand a refund.

I think your memory is loose or damaged. Try cleaning it with an eraser and brush it with a clean paint brush then reinstall it in your PC. Test run it.

Hi,

first try booting the laptop and pressing the Fn key with the numerical ( numbered key ) that has a picture of 2 screens on it. This is for booting to an external monitor. you could also try adding an external ( pc monitor ) this will eliminate any motherboard Faults.

Secondly, the graphics chip driver may be corrupt or not installed correctly. if you have a restore cd, you could try booting the laptop, with the cd in the drive.

you can then try, to see if the settings in the bios are all correct, by booting/starting the laptop and pressing esc or F2 or delete immediately as the laptop starts. ** Be-Careful** what you adjust.
My suggestion is to look for. ** default settings tab** or load setup defaults.

these are the obvious things to try, before assuming that you have a faulty graphics chip or motherboard fault.

My Acer Aspire V5-571 does not load up it shows acer screen when turning on the laptop then loading floating ball comes on screen for a few seconds then black screen ? can any one please help ?


Hi Jim,

this seems like a no boot / no video kind off issue and mostly is coz of corruptions in softwares or drivers, try booting the computer in safe mode. if it does, then take a data backup. i would not recommend experimenting in this issue as it can crash the computer.
hence call 1-877-805-1027 for expert help.

Acer Aspire Z5763 all-in-one suddenly gave "no signal" on screen and then display went blank.


This is a pretty nice system. I don't know if it has HDMI output that you can try connecting to a TV?

When you get that message on a typical desktop, usually the cable has come loose. The same can happen inside these units.

Are you familiar with doing a 'Safe Boot'? When you start the computer and before you go into Windows, keep pushing the F8 key.

An option that comes up will be to Boot Into Safe Mode. If your screen comes up normally in Safe Mode, then you only need to update your display drivers from Acer. If you can't see your screen, you probably need someone local to fix it. The repair isn't hard, it just may be intimidating to someone who has not done it before.
