Did you remove the ram and check the gray cable that connects the screen to the bottom board?

Did you remove the ram and check the gray cable that connects the screen to the bottom board? Yes, I've checked it and still can't start it

Two (or three) procedures come to mind:
1) PRAM reset (although it could be moot if you don't get the chime at all)
2) Power manager reset type 1: Remove all power, wait 3-5 minutes, then connect AC but it sounds like the second mode might be more useful.
3) With a paperclip, hold down both the Reset and Interrupt buttons on the rear for 5-10 seconds.
With all power sources removed, maybe the manager needs a reset.

Leave it plugged in, without battery for a while - see if it boots then. Some rarely used 1x0 machines I've come across take some coaxing to revive, often starting for a moment, power down then become longer lasting. The PB 180c also has a fuse which often dies and an be shunted with thick gage wire.
Another weak point is the PSU, then DC jack, and ensuring the CPU daughter card is reseated and shimmed properly.

我想到了两个（或三个）过程：
1）PRAM重置（尽管如果完全不听到提示音，可能会引起争议）
2）电源管理器重置类型1：断开所有电源，等待3-5分钟，然后连接AC，但听起来第二种模式可能更有用。
3）用回形针同时按住背面的“重置”和“中断”按钮5-10秒钟。
移除所有电源后，管理者可能需要重置。 Thank you, I have tried these methods, nothing happens, this machine looks very new, but nothing happens when plugged in, nothing at all.

PB 180c 将其插入电源，暂时不用电池-查看其是否启动。我遇到的一些很少使用的1x0机器需要一些时间才能恢复运行，通常会先启动一会儿，然后掉电，然后持续更长时间。还具有一个经常熔断的保险丝，并用粗的规规导线分流。
另一个弱点是PSU，然后是DC插头，并确保CPU子卡已重新插入并正确填充。 Where is the fuse, where can I find it, I have browsed some webpages, and I saw someone plugged in the wrong power supply and caused the d15 to burn out (model 180). Is it d15?thank you.

您尝试使用其他电源吗？ Sorry, I don't have any other power for testing.

Well thats the problem its the power adapter Hello, I can't find an original power adapter. I used a multimeter to measure the voltage of the power adapter is about 7.79.
