Hi.

I hibernated my laptop last night, and it won't startup in the morning.

When I try to startup, some LEDs light up (WiFi flickers for a moment, then the Caps Lock, Num Lock, followed by Hard Disk LED which flickers for a moment, then the DVD check). The screen is blank all the time, and nothing happens after this.

What could be the problem?

Thanks,
Ashish

This thread describes a Dell Inspiron 6400 that would not resume after hibernation and then started again after a physical jolt. Two plausible causes are intermittent power/hibernation corruption and a loose or damaged internal component after the fall. noted the machine sprang back to life after a bump; suggested a power-related issue. Both possibilities are worth checking in a safe, methodical way.

Before opening the case try these low-risk steps:

  • Remove AC and the battery, hold the power button for 20–30 seconds to discharge residual power, reconnect AC (leave battery out) and try to power on.
  • Try an external monitor to rule out a broken screen or backlight.
  • If it powers on, run the built-in hardware diagnostics and check Windows event logs, then run disk checks (chkdsk) and a SMART scan to assess drive health.

If the machine behaves intermittently and the impact was near the drive bay, reseating components is reasonable but proceed carefully:

  • With AC removed and battery out, open only the service panels for the hard drive and memory. Ground yourself and keep screws organized.
  • Reseat the hard drive and memory modules, check that the drive bracket and connector are secure, and look for loose screws or broken plastic standoffs.
  • If unsure, remove the drive and test it in a USB enclosure or another computer to verify it spins and passes SMART tests (CrystalDiskInfo or Dell diagnostics).

Do not ignore data safety: back up important files as soon as the laptop is stable. Opening the case can void warranty, and a drive that suffered shock may be failing — if uncomfortable with these steps, use professional service. For model-specific teardown and diagnostics see Dell Support (https://www.dell.com/support/home) and general repair guides at iFixit (https://www.ifixit.com). For background on drive sensitivity to shock see the hard drive overview on Wikipedia (https://en.wikipedia.org/wiki/Hard_disk_drive).

Well... it started up. It seems there is something loose inside, and all it needed was a good jerk, which happened by accident.

This laptop fell on my other Dell, and got a hit on and the area where the hard disk is located. Could it mean that some thing is loose with the hard disk, and it was not getting read? I have never opened up a laptop before, so if I opened up the back side, would it be worth it to try and find whats loose?

It might have just ran out of power while hibernating or there just might be an error.i suggest just clicking on sleep it's easier to use for me anyway.
