Hello and welcome to PCHF Peter Firth,
What do you mean by you reinstalled the BIOS.
Do you get anything at all on the screen such as an Acer logo or does the screen stay black from the moment you press the power button.
Does the notebook normally give out a single beep when it passes the power on self test (POST)
Couple of questions if I may;
What do you mean by you reinstalled the BIOS.
Do you get anything at all on the screen such as an Acer logo or does the screen stay black from the moment you press the power button.
Does the notebook normally give out a single beep when it passes the power on self test (POST)
I would only have contemplated doing that if you were getting a boot failure message on the screen, any way that you can return the new HDD.
Hi and ty... sorry not reinstalling bios but udating.... downloaded from acer support page onto flashdrive... into usb port,held down fn,esc and start button altogether etc.. but no joy... and yeh np bout the return of HDD... no nothing on screen and no beep either...regards...
No problem but reinstalling something would normally suggest that the computer was functional in some way.
AS you get noting whatsoever on the screen and based on what you have done already is suggests that the CPU is bad I`m afraid, I asked about the beep because one of the tests that we often do is remove the RAM and power up to see if any error beeps are given out.
hi again... the CPU you reckon..... welll its about the only thing i haven't touched or changed.... will try to locate one and see what happens.... ty for your comments and suggestions.... will post again to let you know what happens... regards and ty... Peter
well i managed to obtain another CPU,reassembled the laptop yet again and.... nothing!!!.... still the same... power and battery lights on.. HDD light flashes once.. can hear the fan operating.. and a black screen... really dont know what it an be now... got me flummoxed...help!!!!!!!!!!!
Hi Dougie.... yeh tried hooking up to another monitor ... was one of the first things i tried .. no joy there mate..
Summarising all of what you have tried and post here, you have replaced the MB, tried an external screen, replaced the HDD and now tried another CPU, this only leaves the RAM and the notebooks power supply as not being checked/swapped.
When you tried the external screen did you use the Fn and the F5 keys pressed down at the same time to toggle between the two screens.
Were the replacement MB and CPU both guaranteed to be in 100% working order _ can you post links to examples of the MB and CPU purchased.
Hi again.. on the screen question yeh i did toggle fn+f5 to try get the screen working... as for the MB & CPU they came together complete with fan etc and was 100% tried and tested... and Rustys.. the CPU looked ok to me and yeh the thermal paste i put on was pretty much ok to me(not to much, not to little)hope all this helps...regards & ty
Did you remove the RAM and listen for any beeps like philpower mentioned? When there's a hardware fault, in either RAM, CPU, or hard drive, most computer manufacturers have a computer speaker built onto the motherboard that will put out a sequence of beeps and the number of beeps will tell you what's wrong. Did you hear any beeps at all? If you have no display, it's quite likely the display itself is gone since you've replaced everything else short of testing the RAM.
Hi ... no noise or beeps at all when removing either ram ,CPU or HDD... the only sound is the fan operating and power & battery lights illuminated.....ty guys
Because you still get no display after replacing so much hardware we need to consider the possibility that your notebook screen or video cable are bad and that for some reason you also cannot toggle between displays, the keyboard being disabled or bad as two examples - long shot but do you happen to have a USB keyboard that you could try hooking up to the notebook then try toggling to the external screen.
The black screen throughout is a real concern as it suggests serious hardware failure and that you may have been real unlucky with the replacement components.
hi guys.. good news... having earlier noticed Jmarkets comments on having the ram tested i did exactly that.As it was the only thing i hadnt really touched i thought why not.Well the ram was well and truly buggered... obtained new ram,rebuilt laptop and booted up and everything was there ... certainly surprised me(wish i'd done this first) but a big ty to all you guys who took time out to help me out here.... Peter
That is good news and thank you for letting us know 
Just a FYI, on a MB that has integrated graphics only it relies on the system memory to function and as you have now found out bad RAM will result in no display, on a system that normally beeps, if you get beeps when the RAM is removed it suggests that the RAM is ok and that the problem is after that with the graphics device being tested next as part of the power on self test, if you get no beeps with the RAM removed it suggests that the problem is before the RAM which includes the following power supply, MB and CPU with the highest failure rate being in the same order.

I'm glad you got it fixed Peter
