Always a good idea to remove any passwords before flashing.

 

Since it just a hard disk password, the laptop should still boot without it once you remove the hard disk.

 

I'd do like that:

1. Remove the hard disk.

2. Boot the laptop from another drive and flash the CDCN25WW BIOS back.

3. Plug in the original hard disk.

4. Clear any passwords.

5. Flash the newest BIOS again.

So, your laptop is not working anymore?

 

Can you please remove BIOS password before installing the new BIOS?

Hey all. I am new to this forum. I own an Ideapad Y700 15isk. I updated my BIOS today, but I accidentally updated from v28 to v54 directly. I later found out from the same support page that I was supposed to update to v35 first, and then to v54. The lenovo support page, after scanning, still displays v35 under BIOS update. Should I be worried?

If you updated directly and it updated fine, then no issues.

 

Have you verified the BIOS version within BIOS?

Today i updated the pc with Lenovo's official app that was loaded in it. After updating bios it said pc needs a restart but it never started again. Now i ask, what kind of a joke is this? Should we buy expensive apple products in order not to have these cheap update problems? Now it doesn't turn on, no light on screen. The computer is dead and i don't know what to do.

First of all, the BIOS installtion needs to have defaults set in BIOS.

If you really want to diagnose then please do the following -

 

1) Disconnect power adapter and Press power button for 45 seconds.

2) Reconnect and try to start.

 

3) When you press power button, what happens? Does any light come on?

 

4) Can you try starting without the power adapter connected?

 

Thanks.

Yeah sure. When you press the power button its cooling fan starts to work. Only caps lock light works -no numlock light- charging light is also working, i tried to drain its battery hoping maybe bios resets itself (failed). When you hold the power button for 45 seconds it turns on and turns off couple times. Nothing fancy happens any beep or something. When you plug external hdd it starts to work(no reading only disc turning inside the hard drive), phone is charging. Other than that screen is completely black. No logo no loop no bios screen. Is it possible to fix the damaged or wrong loaded bios via usb. I am not sure what is the problem but laptop shut down after bios update and didn't open again. Also does the warranty cover it? I hope it does because i all did was to download suggested updates from its official app.

Odd issue because BIOS update should not kill a laptop that way.

 

Anyways, you can call Lenovo Support and raise a warranty case with them. Tell them that you were updating BIOS using the Lenovo App and the laptop stopped working. This is covered under warranty.

 

You may be able to recover something using USB, but I would recommend not to go down that route since you are in warranty. Just click Support on top of this page, search for your laptop model and call Lenovo in your country.
