Try booting without the battery installed. You probably will have no change but this eliminates the battery as a source of the problem. If it doesn't boot and you are sure that the external power supply is ok, you probably have a bad motherboard. At that point, the unit needs to be checked out by a pro or a really competent amateur.

here is a manuals and drivers for your laptop -http://www.dell.com/support/troubleshooting/us/en/19/Product/studio-1569

If your BIOS is now corrupt you will be unable to reboot and try the BIOS flash again, not easily anyway

A lot of newer systems have special BIOS recovery procedures that can be done. You will need to consult your motherboard manual or motherboards manufacturers’ site to get these steps

you need to push CRTL + F11 buttons together when you power it up

Remove the card and reinstall it to reseat it. This will make sure the card has a good, secure connection. Then, check the cabling from the card to your monitor.

Usually your recovery drive is a second partition that you don't really have to worry about unless you are using it to store your files. Just make sure not to delete any files that deal with the recovery of your system. Could be called system recovery or recovery.

make window update 2) update BIOS version 3) update the Chipset and RUN the software for antivirus 5) run the software calibration 6) RUN the chkdsk 7) Run the defragmen.8) go to device manager and see if there are conflict hardware.and try it. God bless you

Sound very much like your LCD inverter might be going luckily there pretty cheap and you should be able to find one on Ebay.

An LCD (liquid-crystal display) inverter is a component in laptop computers that supplies the power to provide a backlight to the monitor, enabling the user to view what's on the screen. This component is commonly the culprit when the monitor goes out and can be moderately simple to replace.

I've never heard of that before. Best not leave your computer on the floor anyway. Itll collect alot of dust which can cause a lot more problems.

When starting your computer you will see the message press del or f2 or something to enter bios. Press this and the look for "load default values" you can also try "optimised values" if you see it though your computer may be unstable.

Dell Laptop with bios or hard drive password set ? Unlock your dell laptop using the link below if it display a message that says "this computer system is protected by a password authentication system, you cannot access the data on this computer without the primary or administrator password, when you turn on the computer. This message is what you get if the BIOS is protected by a password. or you get system disabledGo to: http://dell-inspiron-6400-bios-password.biospwd.com to get your dell bios password authentication and get full access to your dell computer, they can unlock almost all dell laptop such as dell inspiron, xps, latitude, precision, studio, vostro

To unlock your laptop using the easiest method available go to: http://dell-inspiron-1300-bios-password.biospwd.comDell password authentication system explained :The BIOS of most modern computers also allow a password to be set for each of the connected hard drives. This password is stored in the service area of the hard disk. Because of this, moving the password protected hard drive to a new computer does not allow access to the hard drive unless the password that was assigned to the hard drive is provided.The ATA Security Mode Feature Set that is implemented in all modern hard drives actually provides for two passwords, a "Master Password" and a "User Password"The User Password locks the hard drive and the Master Password is only used to allow an administrator to reset the user password.The BIOS of many computers will not allow the master password for the hard drive to be changed from the default, so they rarely are. A quick search of Google.com for the specific model of hard drive with the phrase "ATA Master Password" will generally result in multiple web pages that contain the default master password . Hardware tools can recover, reset, or brute-force both the User and Master Passwords.Full Disk Encryption Methods:There are two major categories of full disk encryption (FDE)-software-based and hardware-based. Software-based encryption modifies the hard drive drivers and uses the CPU to encrypt all data as it is written to the drive and decrypt all data read from the hard drive. Hardware-based full disk encryption is built into the hard drive and is totally transparent to the user and does not impose a performance impact on the computer.Software-Based Full Disk EncryptionWikipedia maintains a lengthy list of disk encryption software The two most popular FDE software implementations are TrueCrypt and BitLocker. BitLocker is included as a feature in the Ultimate and Enterprise editions of Microsoft Windows Vista and Windows 7, but has to be enabled and configured to provide protection. TrueCrypt [18] is free open source software that is ideal for individual users, but lacks management features that make it attractive to enterprise-wide deployment.Deployment of software-based full disk encryption in any organization with more than just a few computers requires careful consideration of how the encryption keys will be managed. Great encryption without proper key management is like locking the doors to your house and leaving the key under your doormat. One study on the usage of encryption states that 54 percent of respondents had experienced either stolen or unaccounted for encryption keys and that 78 percent experienced system downtime due to encryption failures in the past twelve months [20]. Full Disk Encryption solutions that are targeted at the enterprise typically offer integration with Microsoft's Active Directory or other LDAP directories for secure key management.In 2008, security researchers created shockwaves by publishing a paper called Lest We Remember: Cold Boot Attacks on Encryption Keys [21]. This paper, and the accompanying YouTube video demonstrate how Software-Based FDE can be circumvented by rebooting a computer that has been left in a locked-screen or sleep state. The attack exploits the fact that Dynamic Random Access Memory

You could have a heat problem. Check the fan and heatsink and remove all dust from the fan and heatsink.

It seems as if this is 1 of 2 things. Either a sick of RAM, after heating up, fails, or the actual socket itself is bad. If it's the RAM, it's cheap, buy a new stick, if it's the socket itself, you would have to have Dell fix it, for a steep price, or use the remaining sockets with larger sticks of RAM if possible.

hello since u have already removed the battery one and reinstalled it try this take a different battery install it on ur computer see if it works i have seen this before try another battery just to see if it works

If you want to reformat to factory condition, then press Ctrl + F11 at start-up when the blue bar comes up with "Dell.com" on it. If you miss it then just let it start up, then restart and try again. If it still does not work, press F12 at startup and select recovery option. Please note, if you have deleted the Dell Recovery Partition this will not work for you. You will need to reformat by inserting your Operating System CD at Startup and booting from that (F12).

you mean bios factory settings?
hit del on start up
and klick f7 it is for optmized seting , or f5 it is for default, sacve to you cmos and that is it
