|
|
Dear all,
My laptop would not power nor charge from AC (boots with charged battery though), after a suspected damage by a non-HP power supply unit.
I got the original HP PSU, but it won't boot either. Something's got toasted inside the MB.
Here is the picture of power socket, and an apparently blown fuse:
Question: can I shorten the fuse's pins to retry the powering on? Where should I start from and continue? I am a noob with an eager want to go ahead and learn.
Thanks in advance;

Thank you for your instantenous reply, however the manual (available from HP site also for free..) is not conclusive wrt. my problem.
Standing by for experts' comments, thanks

This message is for Sledge.
I am trying to fix this exact problem as you. Have you found a solution? Have you shorted the L1 fuse/choke ? |

Hi, chong,
Yes, my laptop was never broken! Here's how:
1. One day my orig.HP laptop charger broke with a big BANG sound
2. I am a void-warranty enthusiast, so I spliced some wires and connected an ACER charger (19V) to my laptop, and my HP booted, but worked 2-times(!) slower (clock feeding?);
3. I left the ACER charger to charge HP's battery, and went to the shop to buy a new charger
4. In the shop they (of course) did not have an HP orig.charger, so I bought a universal one
5. When I came back, the ACER charger did not charge the battery at all
6. When I plugged in the "universal" charger to my HP, it did not charge anymore, nor booted the PC itself.
7. When I tested back the ACER charger, it was not charging/not booting either anymore
8. I made a conclusion that playing with ACER charger/plugging in the original one, burned something in the laptop (since the universal charger booted the ACER laptop without problems)
9. I started disassembling my HP laptop, and posting problem on various forums (see above )
10. Months later I came across an original HP charger, plugged it in and my laptop worked as before!!
11. I ordered an HP laptop charger from Hong-Kong, it shipped and now I have a fill working laptop like nothing happened!...
Confusing factors: HP laptop chargers have 3 wires. 1 shield, one internal(active) wire and one needle-pin in the middle (a control/feedback signal?). You can see on the charger's label printed something like –©–
Now, the universal/original chargers I've tried they shorten the active wire to the control/feedback pin. Sadly I did not check for this on my burned orig HP charger.
The universal charger was perfectly charging/booting other new generation HP laptops (my one is "old", from 2007, HP 6170b), so I had problems returning this item (after I found out my laptop being completely sane)
That's my story. Don't play with 3rd party chargers, kids! Otherwise you will become very experienced )
Good luck!
