Hi,
My laptop HP Pavillion DV5000 gpu Ati Radeon Xpress 200M Rs480 overheats and causes black screen. I took it apart and saw a huge grey metalic heatsink installed over the chip and a thermal pad between. I think replacing thermal pad with a copper shim will cool down the laptop. However I...
Hi,
Thank you for your replies for this problem. I should like to add that I cleaned the laptop properly e the only issue is the GPU overheathing (ATI Radeo XPress 200M RS480M). This part of circuitry has no fan but a big grey heatsinc which seems made of special metal as it is conductive and it...
Hi,
My laptop HP Pavillion DV5000 gpu Ati Radeon Xpress 200M Rs480 overheats and cause black sreen. I took it apart and saw a huge grey thermoplastic (?) heatsink installed over the chip and a thermal pad between. I think replacing thermal pad with a copper shim will cool down the laptop...
Hi,
It was detected 18 bad sectors on my 500GB Samsung HDD by HDSentinel software. Then I performed a low level format with HD Low Level Format Utility after backing up all my data. Now HDSentinel informs disk is perfect no bad sector.
Now I would like to know whether I may use this disk as a...
Hi,
I bought a new inverter for my laptop and I accidentally bent it slightly and it no longer works. I would appreciate very much for some ideias to try swapping components (the ones prone to fail) from this inverter to the old one and then test it.
I have another question: is there any way...
Hi,
I am plannig to replace 18650 3.7V 4400mAh on my notebook battery but the cells available have a positive terminal "nose", which make them longer than the original ones. How can I modify these cells to fit in the battery case? Is it dangerous to use a file to make them lower? Any other idea...
Hi,
Are your power supplies discrete componet based or IC based? Voltage regulation in each case is different. The former the potanciometer middle terminal is generally wired to a transistor base and the latter it is wired to an IC pin through resistors wired as voltage divider. If one of these...
Hi,
I wouil like to suggest testing the Shottky dual rectifier that is located near the capacitors. You can test them with a multimeter on the ohmimeter range usually 2K (for diodes). Put negative prod on the center pin and mesure the other two pins. Sometimes this component is tricky. Mesure...
Hi,
Following the tips given by some forum members I dessoldered the the two power inductors on my HP Pavillion dv5000 notebook and I tested them outside the machine. They were both OK. Inspecting the motherboard pads I could see some corrosion that (I think) prevented current flow to the...
Hi
My laptop begin to enter BOS as the CMOS battery was descharged after being two weeks inactive. I reset the BIOS time and the laptop worked fine for some days. Now when I power on and enter the sistem (Windows XP Professional) it power off suddenly after more or less 2 minutes.
Is it...
I would like to add that these inductors are CPU_Core supply line filters connected to MAX1544RTL 27 and 34 pins and FDS6294 sources and 2xFDS6676AS drains conected in parallel or back-to-back. These two lines are connected together at the output to form VCore output. One of these coils has a...
Hi,
I am trying to repair an HP Pavillion dv5000 laptop which will not turn on. All front leds are off. The AC adapter is OK. I took it apart and checked the motherboard and found out 2 large SMD inductors near ther processor (L8 and L9) which are open circuit. As I have never dessoldered...
