SOURCE: MA2 laptop, not charging battery, changed burnt 4407 chip, no LED now.

I've got power problem and burnt PQ38 4407 MOSFET chip. Mine is trying to start from battery but shutts off 5 sec later (with burnt chip)
Looks like PQ37 4411 has to be replaced. Looks like it's also N channel MOSFET
I'm trying to find a source for it.
Let me know if you can find one

Nominally you might get a more accurate answer by going to support.dell.com and entering the 'service tag' number (on the bottom of your machine next to the 'express service code'.

This machine also includes a field in the BIOS setup program; hit the F2 key when you see the Dell logo to start the BIOS setup program.

SOURCE: Can I put the harddrive of my dell 1525 laptop into the dell 1725

you can get an adapter that will allow you to connect your laptop hd to another pc through the usb port. Your hard drive is probably SATA so you would need a SATA to USB adapter cable.
Something like this cable would work.

I was told I had to replace the motherboard on my Dell Inspiron 1525, and that I needed one with a V-chip or video chip. I'm not sure how to find the appropriate replacement.


why u want to replace the motherboard.... as the 1525 model has gone i dont think u will be able to find the motherboard of dell inspiraon even if find the price will be more then your laptop it self ... if you have vga problem try to find the appropriat drivrs rather rahter than replacing the whole mother board...

I have a Dell 1525 Inspiron that is 18 months old. It will not do anything. When battery charger is plugged in...no lights are even coming on. It has been doing this for 3 days but once in a while after...


Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

My monitor has no display at all


very incomplete thread..i gotta know 1st what is ur system configuration..is all ur system is getting power on..is there any light on cabinet glowing (the power n hdd)..is there is power light coming on ur monitor..is there any sound coming out of the system..or the set is dead..??..

considering that the system gets on but u get no display and assuming that the bios has not been flashed in a wrong way..

probably itz either minor case of loose ram/improper ground/cmos battery..
or major case of faulty or defective smps/cpu/main board short/display adapter or card/monitor

..plz do check the following as in order:..

1) in power on mode, open/unplug the data/vga cable of the monitor from cabinet..see if raster or 'osd' is appearing on the monitor screen..if so monitor is ok..else replace the monitor and see..

2) if u hv a graphics card, replace with a standby or onboard and see..

3) see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..or replace with a standby n see..

4) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..

5) remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistace n many more..resulting an increase in heat..

6) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market) between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..

7) the smps itself may b defective/faulty..check the outputs of smps viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg & grey~sb); -12v (blue); -5v(white); +3.3v(orange)..
the 'oscillator and error amplifier ic', or pwm switching regulator circuit..look for defective protector-transformer/resistance(esp 4.7k)/mosfet..

8) if itz not the smps, then it must b ur main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above 1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector..the crystal clock generator (if cpu isn't heating up)....

always better to seek advise from ur system admin/vendor....

is it in warranty..?? if not..
do it if u r a professional..

check the following:
1) the cmos battery (above +3v)..replace with a standby n see..
2) remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistace n many more..resulting an increase in heat..
3) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market) between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..
4) may b the smps itself may b defective/faulty or can't produce sufficient wattage supply..check the outputs of smps viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg & grey~sb); -12v (blue); -5v(white); +3.3v(orange)..
the 'oscillator and error amplifier ic', or pwm switching regulator circuit..look for defective protector-transformer/resistance(esp 4.7k)/mosfet..
5) ur main/mother board..see with a debug card for mb error..

..plz give higher priority to step3 & 4 (as listed above) CAREFULLY..
