Hi, so my problem is that my laptop was working fine a couple days ago then yesterday the fan started getting louder then it turned off I thought it was overheated over 24 hrs later and still nothing there are no lights when the charger is in except for a flash of the charger dedicated LED when at a certain angle and
My theories on the problem, board level failure, charger problem affiliated with this maybe, battery failure or a faulty DC Jack I think it's called (wher the charger is plugged in)

Any help would be most appreciated ~ Llok

Brief summary and next steps (builds on and ): the loud fan then sudden shutdown followed by no LEDs and only a brief flash from the charger when the cable is moved (per ) strongly points at the power-delivery path — the adapter, the DC jack/cable, or the input protection/fuse on the board — rather than a simple fan or thermal-cleaning fix. Since the machine was already cleaned and still fails to power on, follow a measured diagnostic order before deciding to replace the battery or the motherboard.

Recommended diagnostic checklist (safe, low-cost checks first):

  • Remove battery and unplug AC. Press and hold the power button ~30 seconds to discharge caps, then reconnect AC only. Note whether any activity or LED appears.
  • Verify the adapter with a multimeter across the barrel: it should read the voltage printed on the brick (commonly around 19V). If the adapter LED or measured voltage drops or changes when the cable is moved, the adapter or cable is faulty.
  • While plugged in, gently wiggle the DC plug/jack and watch for LED/voltage changes — intermittent flashes at a particular angle are classic DC-jack or cable break symptoms.
  • If comfortable opening the case, check for an easily accessible input fuse or fuse-like component near the jack for continuity and inspect for bulging caps or burn marks. An open input fuse often explains a dead laptop despite a good adapter.
  • If adapter voltage is present at the jack and the fuse is good but nothing powers on, the fault has moved onto the motherboard power rails (standby/VRM). That is the point where board-level repair or replacement is required; rework/reballing, as mentioned by , is a specialist option and usually a last resort.

Repair priority: adapter or DC jack/cable first, then the battery, and motherboard only after the input power path and fuses check out. Exercise basic electrical safety; if unsure about probing voltages or replacing fuses, professional board-level diagnosis is recommended.

Have you cleaned the laptop recently. I think it has to do with dust.
Open the laptop and clean the fan also clean the heat sink.
After that oil the the fan and let see if it works

When the dust builds up, excessive heat can kill it. That might be why the fan got so loud.
The motherboard may need to be "reworked/reballed" and that may fix it. Check ebay for places that will do it. http://www.ebay.com/bhp/motherboard-repair-service

Really hard to give a definite answer, unless you're in Pittsburgh.
Sorry about the weak answer.
