I am having a big trouble with my acer laptop. I have a acer aspire t180 laptop and the problem when i try to boot the laptop, all the initial Acer logo comes for 2 to 3 seconds and then it goes off. The laptop still is on but no display and i think it's freezing case. I tried to reset the cmos battery but no results.
Please provide some help regarding this
Your help will be appreciated
Hard disk firmware is the software code that controls, and is embedded in, the physical hard drive hardware. If the firmware of a hard disk becomes corrupted or unreadable the computer is often unable to correctly interact with the hard disk. Frequently the data on the disk is fully recoverable once the drive has been repaired and reprogrammed.
The hard disk will spin up when powered on, but be incorrectly recognised / not recognised at all by the computer.
The hard disk will spin up & be recognised correctly by the computer but the system will then hang during the boot process.
Recovering data from hard drives with firmware failure requires low level reprogramming / manipulation of the hard drive. It is not possible for a PC repair shop to do this. Data Clinic have our own specialist equipment that allows us to successfully recover data from hard drives with firmware faults.
Electronic failure usually relates to problems on the controller board of the actual hard disk. The computer may suffer a power spike or electrical surge that knocks out the controller board on the hard disk making it undetectable to the BIOS.
Data Clinic can recover data from all types of electrical hard drive failure.
Although electronic failures can happen to any type of hard disk, we find that Quantum Fireball drives are particularly susceptible to power spikes and quite often it's possible to see visible electrical burn damage around one of the chips on the controller board. Usually, the data on the hard disk has not suffered any damage and a 100% data recovery is possible.
Mechanical hard disk failures are those which develop on components internal to the hard disk itself. Often as soon as an internal component goes faulty the data on the hard disk will become inaccessible.
When powered on, the hard drive will immediately begin to make a regular ticking or clicking sound
Recovering data from hard drives with mechanical failure requires the drive to be worked on in a clean room as the drive has to be taken apart and investigated in lab conditions. Data Clinic have a fully equiped Class 100 clean room which we use to recover drives with mechanical problems.
Do not be tempted to open a hard disk if you suspect a mechanical fault: there is nothing you will be able to do and you will contaminate the internal clean air environment. There is also a good chance that during this process you will destroy any chance that we have of successfully recovering the data.
Often the easiest and the most difficult problems to deal with, logical errors can range from simple things such as an invalid entry in a file allocation table to truly horrific problems such as the corruption and loss of the file system on a severely fragmented drive.
Logical errors are different to the electrical and mechanical problems above as there is usually nothing 'physically' wrong with the disk, just the information on it.
Logical errors can also be tackled with various software tools you can buy off the net, but be warned - if you are intending to run a fix utility on your disk you can very easily make recoverable data unrecoverable. This is especially true when running ScanDisk and Chkdsk on a damaged hard drive.
