Having problems with your Acer Aspire 7720 Notebook ?

Aspire 7720, power button lights up but pc does not start


Answers :

1. Generally speaking, because the cmos battery state low, my suggest is to replace the battery. But the notebook cmos battery usually is rechargeable type, maybe certain component in motherboard damaged. You can try to enter the BIOS to restore the default values of BIOS, if it doesn't work, you should reinstall the system.

2. There may be the matter of power cord inside, bad contact. Exchange a power line to have a try.

3. Pull computer memory out and wipe it, it should be good
Try this:

Remove the power cord and the battery from the laptop. Plug in the power (leave the battery off). Try to power it up. If it powers up, wait until it boots into windows and then slide the battery back on. If everything returns to normal, the battery may have become so drained that it was drawing from the charging circuit at boot time and stopping normal power-up. If still no good (no power no fans) then contact acer and see if you are still in warranty. If so, they'll fix it free of charge. If no warranty, try removing the hard drive from the laptop and see if it powers on. If so, the hard drive is likely shot. Another thing to try would be to remove the ram and clean the contacts on the ram and the ram slot gently to remove any oxidation or dirt that may be there (don't rub off the gold plating). Let me know if this helps
