What is Noisy. Normaly its the fans. You can fix the fans with q20. See nee on facebook Nic fourie for more info

i fixed my Z3771 by shorting the CMOS/BIOS jumper/s. and it worked. Original Problem: Power supply was ok. But the screen was blank, it wont switch on as well. When a lan cable is inserted into the lan port, the lan port would light and flicker. So the motherboard was getting the power supply. but it wouldnt switch on. So opened the back covers, then the metal plate on the right that covers the RAM, etc. And on the motherboard was the two CMOS/BIOS jumpers. its located on the upper right of the CMOS battery in the image. The power supply was supplying the power to motherboard. i only shorted the one marked with red arrow and the pc beeped. So you just take the jumper out and move it back and place it. then take it out and put it back in the original position, U can leave it for a few seconds before returning to original position. then i pressed the power switch and it beeped and turned on, BIOS was reset. I loaded default BIOS to start the PC. Played up twice during OS loading, but eventually windows came up.

hi,
acer h274hl has obviously desing problem at power on/off switch.
it's mecanically very weak and break's it self before end of life whole product. Mine power switch broked after 2 years.

Depending on your location and legistalation monitor should work over 3-10years and manufacturer is responsible to repair OR GIVE NEW product, waranty or quaranteen from manufactory dose not affect rights based on your legistlation.

For Acer this is realy bad advertising.

You can remove switch and use microswitch behind rear panel by screw driver if you do not have time to start war against your computer merhant or Acer. Going service due switch takes 1-3 hours time so most likely you buy new monitor or remove switch.
I did not found replacement switchs from ebay so it is not solution eighter.

Also remeber all bad products and avoid brands whit bad desing.

So, you are not alone!

Hi Lenny,
not god news Im afraid, it sounds as though either your screen or your graphics chip are faulty. Help is at hand though, you could try connecting to an external monitor, but as your laptop is switching off, it is unlikely that this will work any better. You can remove the hard drive any install it into another machine, this should be straight forward, although if the machine in question does not have the corect connections then you will need a caddy. these are pretty cheap and plug into usb allowing access to the data on the drive. Hope this helps.

Acer provides a generic user's guide here: http://support.acer.com/us/en/product/default.aspx?modelId=3959

Remove the Power Cord and battery. Press and hold the Power Button for 20 seconds. Now put the power cord back in and Press the Power Button. Did you see any lights or hear any fans running? If not, your power cord is probably bad.

Turn off notebook. Remove the battery. Press Power button. Notebook should start working. Wait for 15 secs. If the screen still blank press Power button and hold it for approx. 4 seconds until notebook is powered off. Then press power button again. Bingo, problem should be solved.

sure lets do one thing disconnect the power cable and also remove the battery and than hold down the power button for 12 seconds and than put the battery back in and also connect the power cable and than start the system that should work

Try the following:
1) Remove power cord, battery and hold the power switch down for at least 30 seconds.
2) Remove and reinstall your memory module(s).

If those don't do it, get back to me for more ideas.
Thanks!
