330-15ICH, 330-17ICH Laptop (ideapad) EG530 NM-B671
I need schematics for 330-15ICH or 330-17ICH Laptop (ideapad) EG530 NM-B671 board.
My main problem is i can reach (but not always) bios menu if i press power button and hold 30 seconds or more. But mostly i get blank screen unless i reset Cmos. I Cant install OS because its freeze at some point. I suspect for faulty on board ram or corrupted bios. Is there any way to flash bios without using OS.Comment

Hello,
I am in search of a schematic or boardview for Lenovo Ideapad Flex 5 14ALC7.
No power and no charging LED with AC Adapter connected. AC Adapter is functioning at 19V, and also tried another Lenovo AC Adapter -- no charging LED still.
There is an active 19V from the USB-C port to the motherboard with AC Adapter connected, so the port is also fine. I am assuming there is a short on one of the power rails, but don't know where to start looking.
Any insight, schematic or boardview would be greatly appreciated.

I measured all discrete Nvidia card voltages,...11-04-2025, 12:48 AM -
Hi guys,
Today I pulled 5 Lenovo T420 laptops out of a bin at the rubbish tip, and they're old school laptops and they're all locked with a supervisor password.
In the past I've unlocked similar Lenovo laptops, often I used the trick of shorting a few pins together on the chip on boot to get into the GUI and overwrite the config but it doesn't look like that is working with these laptops. I guess Lenovo fixed that trick? I have unlocked some other HP laptops by reading the chip, running a patch and re-writing back.
But I can't work out these T420...11-11-2023, 10:05 AM -
For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.
