Y550 bios update failure - DEAD

Hello, hope all are well

I've ideapad Y550 (4186), it was working very well on windows 7-64bit.

Yesterday, I've tried to update the BIOS, downloaded (15CN35WW(V2.08_x64) from the Y550 drivers' page, doubled click the file, the application started.

There was some charge in the battery, and the charger is connected.

On the bios application, I agreed to start update the bios, after a wile, the laptop hanged and stopped response.

After many minutes, I plugged-out the charger and the battery.


Tried to turn it on, no thing happen

No CPU-fan sound, no lights, nothing to tell me the lap is live Smiley Sad.


What can I do ??


Can any one back-up the bios file ( .ROM or .BIN) from his lap to try to flash it on the bios-IC ?


Or, how can I solve this issue ?



Any help is highly appreciated.

hi mohgaza,


Welcome to the Forums.


Can you try to:

1. Remove the AC adapter and battery

2. Press and hold the power button for 30secs (power drain)

3. Re-insert the AC adapter and turn the computer ON (if you see a sign of life, read on)

4. Upon checking, the Y550 uses a Phoenix BIOS, check this thread on how to recovery the BIOS from a bad flash:


Bios Recovery For ideapad laptops


If the unit is dead, the motherboard might be shot and needs replacement.



Hope this helps

Re: Y550 bios update failure - DEAD

neokenchi, can't we just replace the BIOS chip like in desktop motherboards? I believe this was possible for the Y500.

Just a suggestion on cost savings for Lenovo Smiley Happy

Hello all, thanks for help.
I went to a friend, who helped in disassembling the lap, disconnect the BIOS-IC chip, wrote on it with WinPhlash tool, and reconnected it.
Now the lap works well.

Yes jonas_hendrickx, it is possible. THough lenovo does not manufactures the bios chips and hence you will have to get it replaced/reflashed by local repair shops.

Re: Y550 bios update failure - DEAD

After flashing the BISO-Chip (IC) manually, the camera stopped working,
When i try to enable it through Fn+Esc, a message appears stating that ( no camera device found ) , or something like this.
Power management works well with audio, wireless .. etc .

I noticed that , in bios information, some lines are defined as : INVALID, or ( FFFFFFFFFFFFF ) , like: Model number, .

tried to flash the original BIOS file again ( under windows7 64bit), and the same problem appears.

I've made sure that every thing is connected and assembled well after flashing the bios-chip.

I need help, and thanks in advance.
