hi guys
my lenovo z510 laptop motherboard burned down a few months ago, i sent it to garantee and after two month they replaced it with a newer one(besides there are too many scratches on the lid, the lan protect is broken and changed with another one which is white and my charger is changed!)
the bigger issue is that when i turn it on, the bios takes a long time to start and when i check task manager it show that the bios time is at least 20 seconds(even more, like 34, 35 sec) and other problem is that when i try to go to my bios setup, it's not going through, though I press f1,even I tried f8 to go to safe mode, but didn't work, but when I press f12 it goes in boot menu.
and the other issue is that when i try to install the chipset, it makes a blue screen error and restarts the machine.
i also tried to update the bios version, but displayed an error
is it a bios problem or mother board failure?
I'm really nervous and mad about what happend to me, what should I do now?

With so many problems i would send the laptop back with a note to itemise all the problems you are facing.

Other than that have you tried to press the f2 key or the del key at startup to try entering the bios?

oops, I hadn't tried f2 for bios setup, this one worked, what about the other issues?
especially the bios time and chipset failure

Personally i would return it to the seller for a refund....

But if you insist on tackling this yourself, where did you get the chipset driver from? was it from the manufacturers website?

yes it was from lenovo website, also i tried the lenovo's dvd driver which was with my laptop when i had bought it.
well I didn't pay any money to the garantee to ask them for a refund!

Do you know if you have a recovery partition on the machine? or did you recieve any dvds/recovery media with the laptop? i would suggest reinstalling windows and all the drivers from scratch, are you comfortable doing that?

Also what error message did you receieve when you tried to update the bios?

no there is no recovery partion, it is just formatted, all clear!
and no recovery media, yeah i will install, what if I install a windows 10? is it better doing that?

not a specific error it was, just when the pc shut down, it went to a something which was like a bios screen, and displayed an error saying failed to update...

Download the Windows Media Creation tool for Windows 10

http://www.microsoft.com/en-gb/soft...

download the appropriate version of Windows for your laptop and try to update, esure you have all the windows updates for your current OS first before you attempt to perform an upgrade.

Incorrect BIOS time could be a faulty CMOS battery (often coin sized CR2032).

Always pop back and let us know the outcome - thanks

Well you could try replacing the CMOS battery:

or you could return the board.

Your problem has some similarities to that discussed here:

You might want to read his # 6 there.

I called the repairman for the slow bios time, he said this is natural because we have installed a diode bridge on your motherboard to control and protect the board from unbalancing voltage!
does what he said make sense? or he is lying!

Be careful of BIOS updates. They should only be used if they definitely claim to fix an issue you are having. Mostly they are for such things as accommodating a different CPU. BIOS Updates should not be done on a routine basis like other updates. They are rarely needed and if they go wrong they can kill your motherboard.

Always pop back and let us know the outcome - thanks

I can't see how a 'diode bridge' could slow things down that much. After all, as I learned in college, electrons move really, really fast! If they added that it's probably to protect against polarity reversals:

http://electronics.stackexchange.co...

In my link in # 13 the fellow mentions a 'manufacturing boot sequence' option in bios setup which apparently slows down a normal boot. You might check to see if that's set as an option. You might want to just try setting everything back to 'default' in bios setup.

thank you for your helps guys
i left my laptop for a few minutes then when I came back, it went to sleep and when i pushed the power button, the black screen which was taking around 20 seconds before, didn't even pass and it freezed right there, i held the power button and it turned off and when i tried to turn it on again, didn't work and it was still freezing on the black screen and never showed the lenovo logo, so I called the repairman and sent it back to him
is it a board failure?
hope they fix all these issues, thank you guys
I will call you when i get the laptop back

Well, if it didn't even show the logo then it's almost certainly a hardware fault and the motherboard is a likely culprit.

That should be a warranty repair given the new board failed so quickly. It's probably a good idea to bring that up with them so there's no misunderstanding once it's fixed.

hello again
my laptop finally is back
but with series of other problems!
first, the keyboard is exchanged, but I don't know why while it didn't have any problems.
during the first day the screen went black sometimes(i mean flashing, seems like the flat cable faced problem),and it has faced two sudden shut downs!
actually it was flashing continuously and then turned off meanwhile the fan started to turn fast! and when I turned it on again it was flashing, but it is not right now, even I shake my laptop and flicker the lid to see if it flashes or not. actually I wasn't even touching my machine when it started to flash!

Maybe a connector at one of the cable ends needs pushing further home.

When a fan runs fast it is usually due to overheating.

It sounds as if your repair people are not doing a very good job. Everything you've mentioned so far points to hardware.

Always pop back and let us know the outcome - thanks

It sounds they (service centre?) simply replaced your laptop with another one "laying around". You laptop should be return in a working state with at least the Original software installed.

My suggestion is to return it to the repair centre and don't take anything back until they can show you it works correctly!

Success

it encountered the same issue again, seems the VGA has problems, because i was playing call of duty:AW, it was flashing, then suddenly it crashed and when i tried to open my gpu panel, it wasn't installed, i tried to install it again then the driver displayed the message that there is no VGA found, and when I turned it off, it died!
i sent it back to the repairman.

F8 will NOT get you into safe mode. M$ did away with that with Win8 & Win10.
