Help with Dell 1501 Laptop

[Howie]

Hey guys, I need some help with a Dell 1501 laptop motherboard.

I'm trying to identify a part that was damaged near the charging port so I can buy a replacement.
Below is a pic of the same model board with an arrow pointing to the part.

I know this isnt much to go on but a simular looking part was on the reverse side of the board and had: TXCefod 25.000 written on top. It appears to be some sort of crystal quartz peice but no clue on the exact part, type or specs. Hoping maybe someone here has addressed this or has a schematic to look this part up.

No one has any ideal what this thing could be?

Hi, you need a qurtz rezonator for 25 MHz ! It is the resonator for your network card.

The part on the bottom of the circuit board to the right of the battery terminals right most very close you will see a 3r3 coil under that are 2 black mosfets side by side then the 3rd big brown smd ceramic capacitor not the other 2 small ceramic caps directly above its the bigger brown smd cap just above pr11 is what I need specs for, It blew open need to know the values its not on my dell 1501 schematic, forum wont let me post a picture please look at top of this thread for picture

You should be able to post attachments. Do you see the 'upload attachments' button on the lower left side of your window?

What other markings do you see on the silk screen? Something like 'LA-****' or similar?

La ill check now no LA - on silk screen no marking on part taking a up close picture should be uploaded by 930am or sooner no good having issues with picture to my computer figure 10am

Do you mean the yellow / brown SMD parts as attached? These are polarized tantalum caps. Do you have either one still onboard?

The part looks like its beige or white rt side as pictured you see it blew out on the right side note your picture on the left side that 3r3 then 2 black objects 8 pins each then 3rd rectangle looks like its brown on your picture it's right above silk screen pr11

I see on your picture at the bottom 3 of them small to big capacitor its brown on your picture

The part is circled in red

This is a non-polarized ceramic capacitor but not sure of its value or voltage rating. For the voltage rating, you will have to measure the voltage to ground of each of the PCB pads used by this component. One side will most likely be ground, the other side will be the operating rail. The capacitor must be rated at a higher voltage than this measured voltage.

The computer is turning off and on without pressing the power button with battery in and with it removed does this like 5x plus then went off. I unplugged cord and plug back in starts going on off on offf on offf fan spins for a few sec voltage at part is 19.53v dc when it's on I see it drop to 19.22v off and plugged in reads 19.53v its turned off and on 12x plus, Then i pulled the power plug note lcd screen is disconnected ,and i removed the hard drive the ram is installed when it first started doing this id hear the hard drive spin up then turn off to prevent damage i removed the hard drive..
