No, don't mess with the surface mounts.
You don't even know their value!

My CQ61-411WM doesn't boot anymore. Symptoms:


Hi

If the graphics card was intact, the external monitor test would have given you an image.

Unfortunately, this seems like a graphics card problem common to this manufacturer (google HP Compaq Notebook Graphics Problems).

This fault can be repaired only by specialist laptop repairers with specialist tools.

The repair is called Reballing the Ball Grid Array.

Reballing has a marginal success rate and even if successful, the fault can reoccur. A typical professional repair warranty would give you 3-6 months post-repair warranty.

Sometimes the surface of the graphics chip is too damaged to repair.

This repair can be expensive as it may involve several time and labour intensive rounds of disassembly, repair, reassembly and testing.

If you do opt for repair, ensure that the repairer is a specialist, properly equipped with an Infra Red Workstation, experienced in this specific type of repair, is willing to do a No-Fix-No-Fee Repair and offers a Repair Warranty.

If the laptop's warranty has expired and the repair cost seems high to you, it may be time to consider a new laptop.

Sorry for the bad news.

Hope this helps.

Is there a fuse in the laptop. I have power to the laptop but nothing goes on


Laptops do have a fuse near the DC power jack but it is soldered on to the board so it can't be changed. More likely than that you have a bad power jack. If your symptoms were intermittent charging or powering which got worse with time or if you wiggled the power cord you might get a connection it is probably the DC jack. These are repairable but require dis-assembly and some light soldering. If you are uncomfortable attempting that a shop usually charges about $80 to do it. To try it yourself download a service manual for your model, purchase the part (about $10), and give it a try.

Hi My panasonic microwave nnv672s Inverter has stopped working. It powers on and goes for about 15 secs then stops. when in grill mode it is fine though. what should I do


I had the similar problem with my 667. My model had on the right hand wall a plastic plate covering the microwave emitter, secured by one screw. It is made of plastic so care is needed to remove it. I tried cleaning its surface with a number of methods, but the only one that worked was to take sharp knife edge to the surface ie. literally scrap the baked on material. Care in replacing this plastic shield is advised since it can crack if bent too much.
At first, there was no change in the prior symptoms and it even stopped working altogether. Since the "1" button gets used the most, I tried other numbered buttons and now it seems to be working correctly.
Hope this helps solve your problem.

My acer aspire 5315 wont turn on I press button and it lights up as if gonna come on but screen stays blank and then it powers out its only 1 year old help


Maybe the screen has some problems, or try clicking to the power button for some minutes, or Try charging the laptop, or try to change the laptop's battery.

This is all I know, wish it works :)

My dell laptop does not start


Generally, it is an indication that the system is not receiving power. Here are some possibilities:
  1. Bad AC adapter, not providing any/enough power to start system/charge battery. Try a different AC adapter, see if anything changes.
  2. Bad damaged AC connector on motherboard. If the power connection to system is wobbley and not firm, then the adapter plug may be broken. It is possible to got the plug repaired/replaced but generally this is a motherboard replacement.
  3. A component is preventing system from starting. Remove all customer removable items (HDD, CD Drive, RAM, Modem, Wireless Card & battery) see if system will power on and give any error codes (The lock lights on/flashing) If the symptoms change with the removable parts out, then add them back one at a time and see if the system will turn on. If no change, again, replace the motherboard.

If power supply is supplying correct voltage, then you do not need power supply PCB.

Try starting the laptop with AC adapter and no battery, if battery is shorting out you may get same problem.

Test the soldering joint on the AC socket and laptop motherboard, if there is a bad soldering on laprop ac adapter socket, you get same symptoms.

If it is none of the above, and the adapter is fine, then it is usually a faulty motherboard.

Hp power supply failiure


Hi,

Ive worked on a friends G7000 series laptop, since it had the same symptoms you have with yours.

I tested it on my own(identical) working charger/PSU and still no charging.
After taking the motherboard out, i traced the fault to a short circuit FET (field effect transistor) with the PCB reference of PQ1, located right next to the connector for the DC power jack loom.(short from gate to source) The FET is made by Fairchild Semiconductors and its part number is FDS6675BZ. Being in the UK, i ordered the part from www.farnell.co.uk at a cost of 56pence. After changing this FET(which is there to control power) the laptop is working.

If you are not good with very intricate surface mount soldering, then i suggest you buy the component, take the motherboard out of the laptop(not too hard) and take them both down your local TV repair shop for them to check and change it(tell them the board reference PQ1).. shouldnt cost more than £20 or so been as they dont have to fault find.
