        as far i havent 3.3va and 5va and 12va i looked the diagram and chip u6 got 19volt on pin 22, 19v on pin 5-6-7-8 of U16 and u20, but 0v on all other component. where i have to focus to find where the problem is? that chip circuit is a bit complicated to trace.

        edit: u23 pin 4 is short. C264 is short both angles. so maybe c264 or u23 are bad...?

        removed U23, still short. replaced it and removed c264 but still short on pin 4 of U23.

          There is few probabilities C264 being in short, probably chip U6 or u23 would be the culprit.

            removed c264 but still short, so i think problem is u6. bad thing is that if i order from china, i'll take 30-60 days to arrive..

                    tnx for reply; i have to admit that this one was an easy fix

                    very few lapotop needed so small change to make them working again. lasta one was a macbook that need a fuse change; another one just psu replace

                        [REQUEST] Fujitsu Lifebook E5513 – Full BIOS Dump Needed (.bin)
                        by TacticalFahrrad
                        Hi everyone,

                        I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
                        BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.

                        I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain...
