Specs: Windows 7, 4gb ram
I am using lenovo z560(windows 7).when i switch on the power button on my laptop.I am getting the beep sounds continuously.I am changing the bios options (load default settings and saving the settings) is allowing me to use my system properly.Repaired the windows,it does not help me .
bios is insydeh20.Please somebody help me.
my guess(till I don't know software or hardware issue)
1. continuous updates from Microsoft
2.BIOS(have to upgrade bios)
3.Drivers not updated
I am assuming this is not an hardware issue as i used till now without problem.
It is not even (felldown/no scratches) but suddenly problem came.
when i searched in youtube, i found a similar problem(acer).
As this is new and getting problems, I could not sleep properly.
please somebody help me ASAP.

POST beeps = hardware failure/error or memory read/write error, it cannot be the software because POST occurs before the Master Boot Record (MBR) is loaded, therefore it could be several factors:

I would suggest you give the laptop to somebody that knows what their doing, and ask them to reset the CMOS.

Do this by referring to your manufacturers website and looking for the motherboard JBAC1 jumpers, they are 3 pin, and you would for example:

Swap from:




(i being the exposed pin, | being the jumper)

leave for 10 minutes (i forgot to mention, power off and unplugged before you do this!) and then swap back the jumper to its original state.

It will reset all CMOS settings, voltages etc.

If you dont have a jumper, just remove the CMOS battery, leave for about 30-40 minutes and put it back in. Remember to press the power button a couple of times after you've unplugged everything to ensure youve discharged any electrical charge out of the capacitors, and use an anti-static wrist strap if possible to prevent damaging any other components.

Beep codes:
Look up your BIOS and see what it says but I suspect your memory or possibly your hard drive. See what code you get with the hard drive disconnected and you try posting, look that up too.

You have to be a little bit crazy to keep you from going insane.
