I have this Lenovo Slim 7 16IAH7 notebook that is not booting properly. All voltages are there: 5v, 3.3v, 1.8v but it's still a no-go.
I spotted this IC chip with markings "6611c" on it. The coil near this chip measures around 200 Ohms which I think is too low. But without the schematics, it's just a guess.
I wonder if someone has the schematics for this board or perhaps, can help me identify this particular ship. Thanks.... -

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.

Request: Lenovo ThinkPad T14 Gen 2 (Intel) Schematics/Boardview
Hi everyone,
I’m looking for the schematics or boardview for a Lenovo ThinkPad T14 Gen 2 (Intel) with the following board:
HT4B07HP4B0 / HT5B1 / HP5B1 / HT4B2 NM-D352 Rev: 2.0
I’m currently dealing with some startup issues and would like to test for shorts. Any help would be greatly appreciated.
Thanks!

I have recently purchased a Lenovo ThinkBook Plus Gen4 Twist with Dual Screen. Here are the links for the product information:
ThinkBook Plus Gen 4 (13″ Intel) | 13.3″ & 12″ Dual-Screen 2-in-1 Business Laptop | Lenovo UK
However, somehow the serial number and the product name is no longer showing under the BIOS, Windows 11 or Lenovo Vantage.
Strangely the laptop's under cover does not show any information about the Make, Model, Type or Serial Number (No sign of tampering but no labels etc...). I am not sure what to do.
I do not have access to the original box...06-21-2025, 11:09 AM
